LETTER TO OUR CUSTOMERS 

Dear Friends: 

Edson5 newest Catalog represents all the latest developments from 

our 122 years of designing and manufacturing bilge pumps and marine 

steering systems . We owe a deep gratitude to not only our staff here 

at Edson. but to you. who have contributed many excellent suggestions 

and comments . 

The corporation was founded in 1859 by Jacob Edson. who lived 

in the Boston area and invented the diaphragm pump . Other early 

products. produced by Edson. include deck hardware such as anchor 

and cargo winches. portholes. galvanized sheet metal pumps. and 

worm steering systems . Later on. Edson produced the Geared Quadrant 

Steerer that was used on virtually all early catboats . A product now 

out of this catalog. but even though first produced in 1895. we can 

still furnish spare parts . 

The large worm steerers were favored for the large schooners of 

the early 19005 . Among them were King George V's "Britannia", Kaiser 

Willhem 5 "Meteor III" and many. many others . 

Edson takes great pride in the development of new products and 

new ideas and the catalog illustrates over 15 new steering and pump 

products all designed to broaden the Edson specialty of steerers and 

pumps . 

The Edson Corporation is committed to bringing you the finest in 

quality products and to continually add to our line and to give you 

the very best in "Sudden" and "Reliab1e"service .

CRAFTED WHEELS 

These beautifully crafted wheels will give years of service and 

pleasure to the owner who wants the best workmanship on his 

yacht, work boat, or fishing boat. These are not mass production 

wheels, but are all hand made from throroughly seasoned stock, 

carefully selected for matching grain and color. Rims and felloes 

are rigidly secured by brass fastening capped with holly plugs. 

Each spoke is hand fitted so the wheel cannot loosen at the hub, 

an important feature not found on production wheels.

DESTROY E P WHEELS 

The most popular of all Edson Steering Wheels was originated -. 

by Edson and is a registered Trade Mark of this Corporation. 

Edson offers four models including the stainless steel wheel the 

vinyl coated wheel, the leather covered stainless steel wheel and 

the teak rim wheel. Being smooth, they do not catch clothing and 

with their lightness are very sensitive and eliminate the flywheel 

effect of the heavier wheels. With the Fig. 698 wheel adapter and 

our ability to manufacture virtually all specials, these wheels are 

adaptable to most all makes of steerers. Wheel sizes 18" to 40" 

are six spoke wheels; 44" to 72" and larger are 8 spoke. Larger 

sizes are available upon request.

A GUIDE TO SELECT NG YOUR STEERING SYSTEM 

Not too long ago wheel steering was only associated with large 

ocean racing and traditional sailboats. The rapidly growing trend 

towards wheel steering has changed to include cruising and rac- 

ing sailboats as small as 18 feet. Many people once believed the 

only way toget theUfeel'-of a sailboat was with a tiller.The popu- 

larity of wheel steering as well as its practicality has shown even 

the most adamant tiller man that "better feel" and "better boat 

control" can be obtained with wheel steering. Without the tiller 

sweeping theentire cockpit, the crew can perform more function- 

ally, guests can relax more comfortably, and short-handed 

family sailing suddenly becomes simple. 

Planning a steering system for a tiller conversion, or an option 

on a new boat is not a casual matter and should be done with the 

utmost thought and consideration. More time should go into the 

planning of acockpit than any other part of the boat, this is where 

the crew spends the vast majority of their time whether the boat 

is for cruising or racing. Moreover, the cockpit is the base for 

handling sails as well as steering. Thus, in this one area of the 

boat, comfort, convenience, performance and safety are all 

equally vital factors, neglect even one and the pleasure of sailing 

is in ieooardv. 

A major part of planning agood steering installation islocating 

thesteerer. This must take intoconsideration location of the rud- 

derpost, winches, main sheet, and engine controls. All must be 

located properly or moved to the appropriate location for a func- 

tional and comfortable cockpit. 

The aft cockpit steering location is normally associated with 

, ,the older traditional design where a worm gear type steerer at- 

iachesdirectly to a rudderpost located in the aft end of the cock- 

'Opit. It is also the location used for the New Edson Rack and 

:@ Pinion Steerer installed abovedeck directly toarudderpost locat- 

ed in thevery aft end of the cockpit, or with atransom hung rud- 

der. The pedestal typesteerer is often located well aft in thecock- 

pit in cruising and racing boats (minimum distance 21 inches 

from the pedestal centerline to the aft cockpit bulkhead). 

Theadvantageof any of theseaft steering installations is that 

the helmsman is well aft out of theway of crew members working 

winches. From this position the helmsman sees all the action, 

can cast off sheets or tail winches, participate in cockpit conver- 

sation, and has a complete view of the sails and rig. 

In the mid-cockpit installation the helm is farther forward 

where the boat is wider so the helmsman can get more outboard; 

instruments mounted in the cabin bulkhead can be'easily read; 

the winches and cleats are more accessible to the helmsman 

whether they are forward or aft of the helm. On a cruising boat 

this location clears the aft end of thecockpit forcrew members or 

guests not needed for handling sheets. Neither the backstay nor 

main sheet need interfere with the helmsman standing behind 

the wheel, and the helmsman has sufficient room to brace his 

feet without restriction. With the helm in mid-cockpit, winch 

location does become critical, especially when installing wheel 

steer in^ in an exist in^ cock~it where winch locations are fixed. 

concentrating both winches and helm in the middle of the cockpit 

can be most inconvenient for both helmsman and crew. 

The forward cockpit installation places the helmsman close to 

the companionway .under the protection of a dodger, out of the 

way of winches and main sheet, and in a wide part of the boat 

where head sails can be easily viewed. 

,f~i)~ho~~ing the type of steerer is specifically covered on its 

,_I , ppropriate page of this catalog, however, each has certain characteristics 

which are best suited for a particular type boat. 

Rack and Pinion Steering is most useful on boats from 16 to 40 

feet where space under the cockpit floor is limited, or for those 

small sailboats with transom hung rudders, such as the trailerable 

models. The inboard rudder models that are particularly well 

suited are those with the rudderpost coming through the aft 

bridge deck, or the very aft part of the cockpit floor. The Rack and 

Pinion can virtually be plugged into these set-ups with a mini- 

mumamount of installation effort with the exception of building 

a cover over the steerer to serve as a helm seat. 

Worm Gear Steering is often referred to as "Non-Reversing". 

meaning the feedback from the rudder will not normally turn 

the wheel when the helmsman lets go of the wheel. These 

steerers are most often used on traditional boats with aft raked 

inboard rudders. Because of the rake, it is often impossible to 

install a quadrant underthe cockpit floor. This type of steerer is 

attached directly to the rudderpost above the cockpit floor at - 

right angles to the rudderpost. The steerer shaft may be fitted 

with a universal and an extra bearing to build in the exact wheel 

angleforacomfortaljle helm. A wheel box must be built overthe 

steerer to serve as a helm seat .This box can be kept as narrow as 

possibleso the helmsman can sit behind oralong side the wheel. 

The box can have a flip up top to serve as a seat back for long 

watches at the wheel. Engine controls can be located right on the 

sideof the helm seat within easy reach of the helmsman. Despite 

the worm gear steerer being non-reversing, there are always 

those boats with an exce~tional weather helm. or oarticularlv 

hard steering. For these boats, we now offera fridtion 'shaft brak; 

for all sizes of worm steerers. 

Bulkhead Steerers are most advantageous for power boats, 

motorsailers, two station steering Mid-Ship Cockpit boats, and 

bridge deck console type steering stations, generally found on 

custom racing boats. Bulkhead steerers can be purchased for 

very small boats using direct sprocket and chain drive as well as 

2:l and 3:l geared reduction sprocket and chain steerers for very 

large commercial vessels, such as fishing boats and tug boats. 

Pedestal Steering is well suited for both mid-ship cockpit and 

aft cockpit boats with inboard rudders as well as transom hung 

rudders. This system requires space under the cockpit floor for 

mounting sheaves, sheave bracket, or Radial drive^^ Steering 

System. It offers maximum flexibility in that any number of 

sheaves may be mounted to route wire rope around engine 

spaces, through aft cabins or around fuel tanks, etc.The pedestal 

type system comprised of sprocket, chain and wire rope can be 

used very efficiently for both cruising and racing boats up to 80 

feet by varying the size of the steering wheel and the size of the 

quadrant toeffectively changethe poweroutput necessaryto sail 

your boat. This steerer is very popular and most versatile when 

planning your cockpit for "convenience" accessories, such as 

brake, guard, tables, instrument housings, engine controls, 

helm seat and auto-pilot drives. 

Pull-Pull Steering is a new system offered by Edson as an 

alternative to a sheave and wire rope system. This System 

can be used with either Bulkhead or Pedestal Steerers with 

inboard or outboard rudder boats. It is most advantageous 

for Mid-Ship Cockpit and Aft Cabin boats when routing the 

steering cables from the Center Cockpit to the rudderpost 

can become complicated. 

The Pull-Pull System uses standard Edson components in 

conjunction with flexible conduit housing 7x 19 stainless 

steel wire rope. Unlike push-pull cables such as those used 

on engine controls, pull-pull is always in tension. The result 

is very positive steering control without the play and lost 

motion generally associated with a Push-Pull Cable. 

Each steering section of the catalog shows a chart for select- 

ing the recommended size steering system for your boat. Each 

chart is composed of information gathered from our many 

years of leadership in marine steering. Due to the many varia- 

tions in yacht design in areas of hull shape, engine horse- 

power, and sail configuration, final recommendations must 

be approved by your Naval Architect andlor,builder.

board rudder, racing and cruising boats to about 40 feet, these steerers offer the 

answer for those requiring a compact, powerful and sensitive wheel system for their 

craft. Positive response provides the helmsman with complete feel of the rudder.The 

transom hung models offer 1.6 turns of the wheel lock to lock in 70" and the inboard 

models, 1.8 turns to lock in 80". Easeof installation is primary feature.Transom hung 

rudder models attach directly to the rudder through a slot approximately 2"x 6" in 

the transom. lnboard rudder models attach to the rudderpost or rudderpost extension 

and are available for mounting either fore or aft of the rudderpost.The steerer frames 

then bolt onto theaft deckorsuitable mounting surface. You need only build asimple 

strong combination seat and cover for over the steerer. Rack and pinion steerers are 

ruggedly constructed of bronzeand bronzealloys with 1" stainless steel wheel shaft 

andhardware. ~hese materials were tested and proven for their extra wear resistance, 

reliability, and will provide years of trouble free performance. 

RACK AND PINION PLANNING 

The Edson Rack and Pinion Steerers are made in four different configurations: 

transom hung rudder steerers, two different types of inboard rudder steerers and a

axis. ~or.boats with forward rakes, or extreme aft rakes on this axis, the steerers 

are available with a shaft universal and an additional bearing. Shaft universals can 

change wheel rakes to 30 degrees in either direction. 

To allow the helmsman to steercomfortabl~, the top of the wheel should be located 

about 32"180.2cm up from the cockpit sole. lnall cases keep the seat low enough so 

the helmsman's feet are firmly planted on the cockpit floor or other brace. If they are 

left dangling the circulation will be cut off and the position becomes uncomfortable. 

~oatswith rudderposts located too low in the cockpit can use the Fig 782 rudderpost 

extender and Fig 675 coupling to raise the steering assembly to the required 

height. 

Edson will be glad to assist in the selection of the correct rack and pinion for your 

boat. Just send in the top and side view construction drawings of your boat or, if 

these are not available, a simple sketch with dimensions and a photograph will 

help. 

SELECTION GUIDE '-L ( 

Rack and pinion steerers are in most cases straight forward. The variables a d 

"A" or shaft length, rudderstock for transom-hung rudders, rudderpost size for inboard 

rudders and wheet angle. Taking these one at a time. 

1. The "A" or shaft dimension is the distance from the axis on which the rudder 

. . . . . - - - turns to the aft face of the wheel hub. If you intend on buildina a helm seat over the 

steerer, be sure to add 6 to 8 inches for ieg clearance between the forward edge of 

the seat and the wheel. If there is any question, make the shaft a little long as it can 

Built in 

Helm Seat be made shorter on the job. 

2. The width of the rudder or rudderstock dictates the size for transom hung rudder 

steerers Fig 341 and Fig 342. If in doubt, get the next wider jaws as you can 

always shim the sides of the casting. The jaws on the gear rack are drilled at the 

time of installation. 

3. The rudder post diameter determines the size of rack and pinion steerers for inboard 

rudders. Refer to the size charts for Fig 343, 344, 346 and 347. 

4. All models of rack and pinion steerers are available with shaft universals if you 

want to raise or lower the wheel angle.

ORDERING INFORMATION 

When ordering a Rack and Pinion Steerer, please specify the Figure number, 

size, type of boat and description. For inboard steerers. the rudder~ost diameter 

and key size is necessary. Unless otherwise stated, the keyway hill be onquadrant 

side. If the steerer is to be used with a tubular rudderpost please sd=, ), 

vise and you will be supplied with a 318 inch pin, pilot drilled through the cap of thJ quadrant. Also advise the "A" or shaft length that best fits your installation. When 

determining a wheel shaft length be sure tb include the thickness of the face of the 

wheel box, space needed for an auto-pilot drive sprocket, or length required for a 

Fig 783 Brake, (about 2-114"). Wheel shafts are 1 " stainless steel and are machined 

to accept Edson Wheels with 1" bore by 2-318" bore length, with a 114" keyway. Inboard

RACK AND PINION STEERERS id RACK AND PINION STEERERS 

Designed specifically for double ended boats up to about 38' 

with transom hung rudders. Edson's new model Rack and Pinion 

Steerer operates in a similar fashion to the standard Rack and 

Pinion Steerer with the feel of a tiller and very responsive to the 

touch. It is available in two models: for straight in-line installations 

on vertical or nearly verticle rudders and for offset installations, re- 

quiring a shaft universal and an adjustable bearing for angled rud- 

ders. They require only a small slot in the stern for the operating 

rod. This slot can be easily sealed with a homemade boot similar to 

one for a mast step. 

Fig.814 Double Ender Rack and Pinion Steerer consists of a Rack 

and Pinion Steerer with lever, 2 clevis units, connecting rod and-a 

rudder lever unit. The geared quadrant is designed to mount on a 

1-112"13.8cm dummy rudderpost. The ''A" dimension is 21 ", theUC" 

dimension is 16" or either is available to suit. Weight 46 lbs.120.7k.

Fig. 613 Outboard Lever Quadrant Assembly consists of a 

12"/30.5cm quadrant (Fig. 668) 2 clevis units, connecting rod, and 

rudder lever unit. This assembly is designed for double ended 

boats which want to use a roller chain type steerer (ie Pedestal, 

Bulkhead Steerer, or Geared Reduction Steerer) in conjunctionwith 

an outboard rudder quadrant. The steering cables can be ledj #) 

aft from your choice of steerers using an appropriate combination -'. 

of sheaves or ~ull-~ull conduit. The quadrant is desianed to mount 

on a 1 112" 13.8cm dummy rudderpost. For ordering &d installation 

instructions, refer to the double ended rack & pinion steerer below. 

INSTALLATION INFORMATION 

First of all it is important to establish and install the reinforced plat- 

form that the dummy rudderpost is going to be bolted to. Bear in 

mind that this surface must be of sufficient strength as it must 

absorb all of the steering loads. This platform must be 90" to the 

rudder on a plane where you wish to install the rudder lever. Also 

note that the geared rack and pinion quadrant requires a minimum 

of 10" on each side of the dummy rudderpost to swing in. This 

dimension will help in establishing the "C" dimensions. 

Temporarily mount the dummy rudderpost and assemble the 

rack and pinion gear and housing. Assemble the clevis, the connec- 

ting rod, and the rudder lever unit. With 'C' clamps, attach the 

rudder lever unit to the rudder. Now operate the steerer noting the 

rudder travel from side to side. The location of the lever on the rud- 

der, either fore or aft or possibly even shimmed to starboard, deter- 

mines equal travel from side to side. Take time with the positioning 

of this lever and be precise. When you are satisfied, secure all parts 

and install stops, such as wooden blocks on each side of steerer to 

limit its travel to the desired arc. Provisions for an emergency tiller 

should now be made if you do not already have one. 


- 

When ordering a Rack and Pinion Steerer for a double ender, 

please specify the figure number, 'A' & 'C' dimensions, type o 

boat, and a description of the location of the dummy rudderposj3, 

with dimensions. Unless otherwise specified, the geared quadrant '" 

will be bored with a 1-112" dummy rudderpost. Refer to ordering information 

for Rack and Pinion Steerers for more detailed considerations 

when determining the 'A' dimension. Individual parts 

are available, see Fig 616, 808 and 836, Tiller Arms. If you require 

further assistance, please do not hesitate to contact the Edson factory 

for more information. 

The Rack Aft steerers are for those boats with at least 12 inches 

of space aft of the rudderpost and limited space forward. The basic 

dimension of the gear should be carefully noted as it is important to 

place the wheel about 32 inches up from the cockpit sole to allow 

the helmsman to steer comfortably. 

Fig 343 Aft Mount Rack and Pinion Steerer - size 1 is for use on aft 

racked rudderposts 1" to 2-118" diameter with a maximum key of 

318" in on the aft side of the rudderpost. If the bore is not specified 

the rack will be furnished with a718" pilot hole. The "A" Dimension 

on the wheel shaft is standard at 15 inches or is available to suit.

WORM STEERERS 

Edson offers three basic models of Worm Steerers: Simplex, Robinson, and Meteor. The Simplex is the most popular model 

c%nd is manufactured in three sizes for boats up to about 50 feeVl5m in length. There are two basic designs of the Simplex; one 

with the worm mechanism forward of the rudderpost, the other with the mechanism aft of the rudderpost. The actual choice 

depends on the space available for the gear, the operating features are identical.

The Self-Aligning Bearing supplied with the gear must be 

well bolted down to a timber or strong moldment on a fiberglass 

design. It is important to design in the basic features 

that make for a successful installation. It is recommended 

FIG 390 Edson Meteor Steerer 

With Worm Fore and Aft of Rudderpost. Wt. 128 lbs.158.5 k 

A = 15-3/4"139.4cm 

that the top of the wheel, the actual part you hold onto, be 

31 "/79cm to 33"182cm up from the cockpit floor. This will 

allow standing beside the wheel without reaching down to 

the wheel, also sitting in back of the wheel or alongside it 

and have the wheel at a convenient height. 

Essentially a Worm Steerer is a non-reversing system 

with little to no "feel" and is most commonly used on a longkeeled 

cruising design. The steerer design features more 

turns pf the wheel from hard over to hard over than is nor-

The Worm Steerers would then not be recommended for a 

short-keeled fast turning boat or one that does not track as 

well as the long-keeled boats. The non-reversing feature will 

hold the wheel in place on most boats most of the time. It 

will give or turn if the boat is hit by a large wave or the boat 

has an excessive helm due to basic design, force of the 

wind, or balance of the sails. The gears are strong and relatively 

heavy as they must stand all of the strain of the rudder 

when transmitted to the gear.

SIMPLEX WORM STEERERS 

For excessively raked rudderposts, Edson offers a Simplex 

with the Shaft Universal Assembly on the wheel shaft and an 

exfra Self-Aligning Bearing for the needed forward wheel shaft 

support. This combination can reduce the wheel angle by a maximum 

of 30" up or down. That is if the rudderpost is at 45" to the 

waterline the wheel can be angled at only 15". Edson feels the 

maximum angleof the wheel should be no more than 20" . Likewise 

on near vertical rudderposts the same universallbearing 

setup can be used to give the wheel some aft rake. This angle is 

important as it will give the helmsman room for his knees while 

the top of the wheel is closer to his arms 

If in doubt as to steerer size or if the boat is very heavy,go larger. 

Do Not compromise the final size. 

For those boats where the rudderpost ends at the cockpit 

floor level, Edson can furnish the Fig 675 Coupling and aFig 782

carefully and if in doubt add to the length of an extension, it can

dst~n BULKHEAD SPROCKET STEERERS 

Edson Bulkhead Steerers are available in many sizes, features, and 

capacities, for small power craft to large schooners and tugs. These 

steerers are perfect for consoles, cockpit dividers, or custom pedes- 

tals. Bulkhead steerers should be selected for the size and type boat, 

and the conditions of use. For selection, we compare all combinations 

shown in the selection chart to the length tiller required. Even the 

smallest bulkhead steerer has the equivalent mechanical advantage of 

a 6 ft.ll.8m long tiller. Lighter boats or racing boats generally prefer a 

fast acting system with fewer turns of the wheel, lock to lock. Power 

boats and heavier cruising boats prefer slower acting, more powerful 

systems. With increased turns lock to lock, more power is obtained 

and chances of over-steering at higher speeds are reduced. The faster, 

larger, or more powerful the boat the greater the number of turns is 

required. If more steering power is desired and the quadrant space is 

limited, the Fig 360 Geared Reduction Steerer is recommended. 

FIG 410 NEEDLE BEARING STEERER 

This steerer was developed for those wanting the finest in steering 

control. Stainless steel needle bearings, stainless steel liners, and a 

stainless steel shaft makes this unit as friction free as possible. Each 

Fig 410 has a Zn15cm shaft extension for connecting an auto-pilot, or 

second steering station. Every Fig 410 is jig drilled to accept a Fig 689L 

Brake which can be installed when ordered with the steerer or installed 

by the owner at a future date. The Fig 410 was designed with an in- 

verted aluminum "V" frame allowing the chain to diverge at a wide 

anale. This feature reduces the total number of sheaves required, thus 

increasing "feel", and reducing installation costs. This steerer can be 

used in a custom pedestal, bridge deck, power boat console or bulk- 

head. In adivided cockpit on racing sailboats the Fig 410 can be placed 

in a bridge deck with the traveler on top. This is ideal for boats with no 

room under the well. It also provides an excellent location for a life raft. 

Fig 410 complete with Fig 689L Brake weighs only 10 lbs.14.5k. This 

steerer accepts standard Edson wheels, with 1 "12.5cm x 2-318"16cm 

long bores. It comes complete with a black nylon wheel nut, key, and 

stainless steel faceplate, weight 8 lbs.13.6k. 

FIG 338 CRUISER STEERER 

An excellent general purpose steerer for both power boats and sailing 

craft. This steerer has a rugged die cast bronze frame, and stainless 

steel shaft. The oil impregnated bronze bearings give years of trouble 

free performance with minimum maintenance. Each Fig 338 has a 2"1 

5cm shaft extension for connecting an auto-pilot or a second steering 

station. All steerers are pre-drilled at the factory to accept optional 

Fig 742 Wrap Around Friction Brake. It comes complete with black

WRAP AROUND FRICTION BRAKES FOR BULKHWD STEERERS 

The most popular accessory for all Bulkhead Steerers. Brakes are designed to dampen 

the action of the wheel, a feature especially handy on long runs orwhen operating under 

power. Can also be used to hold the boat on course under most conditions, while the 

helmsman trims that sheet or goes below. As a safety feature, the brake can always be 

overridden by the helmsman. All mounting holes on the steerers are pre-drilled at the factory, 

allowing simple installation in about 15 minutes. Brakes are constructed of bronze 

--with long lasting brake linings, and supplied with stainless steel brake shaft and 

hiny black nylon brake handle. Brake shafts are available in 8"/20.3cm and 14"135.5 

&) cm lengths. When ordering specify Fig. Number and brake shaft length. Unless otherwise 

specified brake shafts will be supplied 8" long. Brake shafts can be easily shortened 

by cutting with a hacksaw and drilling one hole.-Longer Brake Shaft lengths 

available on special order. Wt. 2 Ibs.l.9k

dsd~n GEARED REDUCTION SPROCKET STEERER 

The Edson Geared Reduction Steerer is a powerful and sen- 

sitive steerer designed for pleasure and commercial boats thirty- 

five feet and over. The reduction steerer will deliver approxi- 

mately fifty percent more power than the bulkhead steerer with 

quadrants of the same size, and is an excellent steerer for power- 

craft, motorsailers, and heavy auxiliaries with limited space 

around the rudderpost. 

Geared reduction steerers are constructed of extra heavy non- 

magnetic stainless steel, bronze, and brass. Additional features 

include oil impregnated bronze bearings, an oversized frame for 

even load distribution, and two inch shaft extension for easy 

auto-pilot installations. All steerers are pre-drilled to easily 

install Fig 742 Brakes (size 2 and 3). Steerers are supplied with 

black nylon wheel nuts, and stainless steel wheel key.

The Fig 410 Bulkhead Steerer combined with a Fig. 628 chain idler 

makes a very functional bridgedeck arrangement, using no floor 

space. You can stand right up to it, and it eliminates the need for extra 

scuppers for a separate compartment. The Edson Fig. 752 Wide

Edson's Offshore RacinglCruising Idlers are available in both bronze 

and aluminum. The bronze is a heavy duty steering package for the 

serious offshore cruiser andlor racer and is available in a size 6 and 8 

inch. The aluminum idler is ultra-light - the latest thing forthe ultra- 

light offshore sled. The idler is light, very strong, and super sensitive 

for the ultimate "feel" of the helm and is available with 6" or 8" 

sheaves and stainless steel pins. In the 8" size needle bearings are 

standard. 

The Fig. 807 Offshore Swivel ldler assembly consists of extra strong 

sheave housings assembled to a large idler plate using stainless 

steel grommets. After aligning the sheaves additional bolts are in- 

stalled, making the assembly very strong. These housings will accept 

6" or 8" sheaves. 

The idler plate is fastened using the 1/2" pedestal bolts, with extra 

holes available for through bolting. The larger idler plate sandwiches 

the cockpit floor, helps reinforcing, and distributes the load. 

The Fig 863 Offshore RacinglCruising Crossed Wire ldler is used for 

those boats having the quadrant aft of the rudderpost. This idler 

allows crossing the wires inside the pedestal to give the proper steering 

direction. The sheaves are fully adjustable between 20" forward 

to 160" aft, and after aligning the sheaves additional bolts are installed. 

The Fig 863 ldler is otherwise the same design as the standard 

Fig 807.

The Fig 806 and 848 Dual Ratio Quadrants are ideal for conditions that 

sometimes call for different steering ratios. Racers may want quicker 

response in light air, more leverage in heavy going, or an easier helm 

for leisurely cruising. These quadrants allow you to shift your steer- 

ing cables from a 10" to an 8" or a 12" to a 14" radius in 15 to 30 

minutes time, giving you a difference of about 10% in leverage. A 

natural for new untried racing machines with big rudders - or adap- 

ting other larger designs to the skipper's or natures requirements for 

the day. The second groove is also ideal for a permanent auto-pilot ar- 

rangement. Available in aluminum or bronze, please specify material 

when ordering.

dsc~n SELECTING A PEDESTAL STEERING SYSTEM 

Edson now offers many types of pedestal steering systems specifically designed for maximum performance and Edson . 

reliability, as well as ease of installation. Each system is pre-drilled to accept any of the convenient add-on accessories at any time. 

Carefully review each type shown in the following pages, as well as the Edson "data-Sheet" for your particular boat. Edson has 

over 1,200 installation drawings which we call S-Data-Sheets. If you own a stock boat, feel free to request a Data-Sheet on that 

boat, or if you are building or purchasing acustom boat send us in aconstruction drawing or good sketch and we will gladly send a 

complete proposal and Data-Sheet representing a similar installation.

BASIC QUADRANT 

-SYSTEM SHEAVUBRACKET SYSTEM 

Basic ~uadrant System is best used where the rudder post has considerable rake forward or aft, or where tanks, cockpit 

drains, exhaust lines or other obstuctions require routing of the wire rope through two or more sheaves. This uses wood 

supports to tie the cockpit to the hull keeping steering loads from wracking the cockpit. This system has been used for many 

years and is excellent for conversion of tiller boats as well as new installations. 

Sheave Bracket System is ideal for installation on stock boats as well as by owners or yards. It is excellent for those boats 

having the cockpit seat risers along side the radius of the quadrant where wooden blocks can be glassed in on the sail locker 

side of the seat risers flush with the bottom of the cockpit floor. This unit has a built in quadrant stop and fully adjustable 

sheaves. 

Radial Drive Steering System is ideal for sail or power boats up to 40 feet with vertical or nearly vertical aluminum or stainless r< ', 

steel rudderposts, whe7e cables can be led directly onto the drive wheel. The Radial Drive can also be used on boats larger than 

40' when using an independent rudderpost stop. On boats over 40' feet Edson would like complete blueprints and requires the 0; 

final approval of your naval architect. This system is designed to be simple and economical with fewer moving parts. Feel and 

performance is equal to other Edson steerers. It can be used equally as well with pedestal or bylkhead steerers on any boat with 

adequate clearance around the rudderpost. It can also be used in conjunction with the Pull-Pull conduit on mid-ship cockpit 

designs or on boats with a variety of obstructions between the steerer and rudderpost.

HYDRAULIC STEERING ADAPTER KITS 

Pull-Pull I with Radial Drive - For sailboats with an aft cabin this is a natural. The Pedestal installation uses a Fig 841 dropped 

conduit mounting plate for attaching the conduit at the pedestal. The conduit is routed along the starboard side under a bunk to 

the Radial Drive. 

Pull-Pulllwith Bracket - is often found where a bunk or lazarette might interfere with a Radial Drive or Sheaves. When a 

bunk is located under the cockpit use the Edson Fig 825 mounting platform shown in the Pull-Pull section of this catalog. This 

installation keeps the conduit neatly up against the underside of the cockpit floor. This can only be used with 6.5" or 8" Radial 

Drive or 8" quadrant dueto chain travel limitations. 

Hydraulic Steering Adapter Kits Edson Steering Adapter Kits permit any of the Edson Pedestal Steerers to be easily;,. 

installed in conjunction with Hydraulic Steering Systems. The below cockpit illustrations show the Edson Pedestal Steerer 

with endless roller chain and adapter plate connected to a bulkhead mount type of hydraulic helmp pump.

SIZING THE PEDSTAL STEERING SYSTEM 

dssan 

" - )The typical installation may vary in wheel size, sheave size, chain 

:dlength, and quadrant size depending on the size and displacement of 

sizes, see the table below. Edson will also supply upon request, Data 

Sheets and specific recommendations covering the best system for 

the boat, and the type of sailing being done. For cruising and offshore your boat. For boats being able to use more than one system, recomwork, 

a larger quadrant with more power output, and more turns of the mendations will be given in order of preference. For specific informawheel 

hard over to hard over is preferable. For racing, a smaller quad- tion for converting or planning your boat, send us your construction 

rant with fewer number of turns and a larger wheel will provide faster drawings andlor sales literature along with the type of steering 

action especially useful for downwind sailing. For recommended system you wish to install. 

The chart below is composed of information gathered from our many years of leadership in marine steering. Due to the many variations of yacht 

design in areas of hull shape, engine horsepower and sail configuration, final recommendations must be approved by your Naval Architect.

Values in chart are for 518" - 11 tooth sprocket. Divide by 1.1 for 314" - 10 

tooth sprocket values. 

The value of this chart is two-fold. One, to get steerer output secondly 

to get a working relationship between steerer output and equivalent 

tiller length. To obtain the equivalent tiller length divide the output 

figure by 40. For example a boat with a 24" wheel and a 12" quadrant 

has an output of 432 ft. Ibs. Divided by 40 this equals the leverage of an 

11 foot tiller. 

Second, it is interesting to note that a 30" wheel with an 8" quadrant 

has the identical output of a 20" wheel with a 12" quadrant the difference 

being the number of turns. The first with 1.8 turns has fast action 

and a large wheel (the preference of most racing skippers). The second 

with 2.7 turns has a sloweraction and a smaller wheel (for the boat used 

primarily for cruising). Which do you prefer? We can fit the steering 

action to your boat.

PEDESTAL STEERERS 

All Edson pedestals are designed for versatile installation in 

virtually all types and sizes of boats. A well designed and well installed 

pedestal with its greater mechanical advantage gives 

better boat handling with more feel than a tiller, and far more 

usable cockpit space. A pedestal enables the entire family to 

handle the boat under virtually all conditions. 

Edson offers 4 basic pedestals. The Fig. 334 is usually used 

on smaller boats and includes a molded compass adapter for 

smaller 3", 4" or 5" flush mount compasses. The Fig. 335 is the 

same basic pedestal as the Fig. 334, only it comes without the 

molded compass adapter and it will accept most all standard 5" 

compasses. The Fig. 400s and 420s Deluxe Pedestals, for larger 

boats, will accept most all 6" compasses, and come equipped 

with extra needle bearings, and liners, and the pedestal brake 

is standard. 

When choosing a pedestal, remember all pedestals look 

somewhat alike on the outside, yet the inner workings are 

most important. For instance, the 334 pedestal comes with the 

same $/8" roller chain used in our larger pedestals. Edson does 

not believe in compromising by going lighter for a smaller 

boat, as the loads can become high under storm conditions. 

All ~edestals are pre-drilled to accept all accessories shown 

in the catalog with a minimum amount of installation time. 

Please note: compasses are not included with the pedestal, for 

compass selection see Fig. 658 in this catalog.

Edson offers a brand new steering installation for many sail 

and power boats up to 48 feet. The system is ideal for boats 

with vertical or nearly vertical stainless steelbr aluminum rudr-- 

) derposts, where the cables can be led directly from the steerer 

~323 onto the Drive Wheel. It is ideal for those boats having limited 

working space under the cockpit floor for mounting sheaves. 

Installation is simple - no extra structure to glass in, no extra 

sheaves to increase friction, and no extra timbers for reinforcement. 

The Edson Radial Drive Steering System* is simple, economical, 

with performance equal to any other Edson Steerer. 

Its versatility allows it to be used with pedestal steerers as well 

as bulkhead steerers. Auto-pilots can be easily installed in the 

Radial Drive Steering System. (See the Auto-Pilot section of 

this catalog.) Each drive wheel constructed of heat treated aluminum 

and supplied with an integral rudder stop. The drive

axis with the keyway on the solid portion of the hub. The dished 

shape drive wheel gives a full 21/2" offset. This allows the drive 

wheel to be turned over giving a full 5" of range for aligning 

with the Idler. It also allows the stuffing box to be placed up in- 

side keeping the bearing capabilities of the stuffing box right at 

the wire load line. Each drive wheel will be bored at the factory 

to your specifications. Otherwise they will be supplied with 

pilot bore (see chart below). The steerer may be installed either 

forward or aft of the rudder post by choosing the proper idler 

shown on the previous page. Bulkhead Steerers with a rudder- 

post within 4% ft. can use these same idlers. When greater use

Edson bronze or brass sheaves are especially designed for use in 

wire rope steering systems. All sheave housings are rigidly constructed 

of solid bronze, stainless steel, or aluminum, and are designed to 

Drevent the wire from ium~ina out of the sheave. Scores are machined 

extra deep, and are concentrk with the bearings to maintain constant 

wire tension. The bearings for all bronze sheaves are oil impregnated 

bronze bearings, aluminum sheaves feature precise stainless steel 

needle bearings. Sheave hubs are wider than the rims to prevent side 

friction and noise. All sheaves have removeable pins to simplify installation 

or wire replacement. In addition, all sheave housings have pin 

arrestor systems designed to prevent premature sheave pin wear. The 

new Fig 620 and 743 "Thinking Man's Sheave Housings" are another 

Edson original. The Fig 620-4" has a stainless steel housing for even 

greater strength and reliability. This is excellent for use on boats of

aluminum construction to eliminate the possibility of electrolysis. ~ ih, bi) 

620 is supplied as standard equipment in all Edson steering systems -' 

for production boats. Edson's Fig 743 is the latest answer for bulkhead 

mounting. Both sheave housings have elongated bolt hole slots for 

aligning the wire lead, along with two additional bolt holes for securely 

locking that setting. The Fig 621 Flat Sheave is ideal for mounting on 

power boats, or under cockpit floors on sailboats. The Fig 623 Double 

Upright Sheave Assembly is commonly used on mid-ship cockpit 

designs on inside steering stations where both wires lead aft on the 

same side of the boat. 

In order to ensure a long life and proper operation of your Edson 

sheaves, proper maintainance is essential. Sheave bearings should be 

oiled monthly; failure to do so will result in premature wear and the 

possible seizinq of the sheave.

Edson Quadrants have all been designed for specific uses and proportioned 

to withstand severe steering strains and shocks. All are 

cast of either Manganese Bronze or 356lT6 Heat Treated Aluminum 

alloy. To simplify installation, all quadrants quickly adapt to the exclusive 

Fig 618 Edson Wire Takeup Eyes. All quadrants will accept 

wire rope up to 318"19.52 cm in diameter. The various quadrants listed 

below are shown by rudder post or bore size, and are available in different 

models including "Space Saving" Offset, standard straight, 

Double Offset and Dual Ratio Quadrants. When ordering please supply 

an accurate dimension of your rudder post or the desired bore 

along with the key size, and Edson will machine the quadrant to suit. 

Edson allows a 5 to 6 thousandth clamping action of the cap to the 

rudderpost. The quadrant must be carefully fitted for optimum 

strength; if it is fitted too tightly the cap could try to bend when 

tightened, and if fitted too loosely the quadrant could work or drop. 

Both the above could cause premature failure. Solid stock rudderposts 

are normally keyed and hollow pipe stock rudderposts are normally 

pinned. Edson will provide the pin with the predrilled cap. Edson 

sees a trend toward machined keyways in hollow rudderposts as 

they allow for easy adjustment up and down the rudderpost. Most 

keyways are 114" square so they do not penetrate the wall thickness 

See "How

QUADRANTS 

of the tube. Quadrants for square rudderposts require special 

machining, and we must be furnished with the exact measurement of 

the flats on the square and the location of the points of the square. 

"Space Saving" Offset Quadrants are ideal for boats needing extra 

room on the rudderpost for the addition of an auto pilot, a second 

steering station, or where an obstruction exists. The "Space Spacer" 

quadrant can also be used for boats with excessively raked rudder- 

posts whether mounted with the offset up or down. Edson's "Space 

Saving" quadrants are available in aluminum as the Fig 842 and in 

bronze as the Fig 677. With new and improved casting methods 

available today, Edson's new Fig 842 aluminum quadrant is designed 

and cast for strength and versatility. It will accept the Fig 857 "bolt 

on" Double Offset Quadrant Segment which provides a second 

radius for use with an auto pilot or with a second steering station. Ed- 

son's new aluminum quadrants are to be used with stainless steel or 

aluminum rudderposts and must be equipped with stainless steel 

keystock or pins when attaching to the rudderpost to prevent elec- 

troysis from dissimilar metals. For those with brass, bronze, or stain- 

less steel rudderposts the Fig 677 Offset Quadrant is available.

) TRANSOM HUNG RUDDER QUADRANT FIG 612 

The heavy duty manganese bronze transom hung rudder quad- 

rant for use on most all boats with outboard rudder, eliminating all 

levers and pins. The Fig 612 quadrants have a total arc from hard- 

over to hard over of 70". The quadrant can be mounted low enough on 

the transom to allow the wires to be led just under thecockpit floor 

to the idler, or it can be mounted higher to fit within the lazarette, 

for Pull-Pull Conduit installations. As in any opening in the transom, 

it must be booted or a drain pan or area must be furnished to pre- 

vent water from getting into the boat. Available in three sizes, the 

Transom Hung Rudder Quadrant can be used with all wire systems 

'Larger sizes available on special request.

One Edson specialty is a combination Rudderpost Bearing and 

above the waterline stuffing box. Edson offers two types of 

stuffing boxes starting with type B for the most common used 

rudder shafts measuring 1" through 3" in diameter. Type B Stuffing 

Boxes are designed to be either fiberglassed in place or fastened 

to the rudderpost tubing with hose and hose clamps. Type C for 

the less frequently used and larger size rudder shafts through 

! 3-112", must be glassed in place. Edson recommends fiberglassing 

STUFFING BOX/BEARING FIG 697 

the stuffing box bearing to the top of the tubing when the rudder- FIG 697 

post is in place. This makes the post a structural bearing and will 

carry the rudder loads with minimal friction. The hose coupling 

method can be used, however when under a load the stuffing box 

type B 

is apt to bend and add friction to the steerina svstem. When used 

with hoses the following sizes can be used: 2': 2-;IT, 3"; and 3112".)

Cockpits are at their best when they have a strong, conve- 

nient hand hold. Edson guards are available in wide and narrow 

models. The guard is designed to protect the compass from 

falling crew members and to keep lines clear of the compass. 

The Narrow Guard allows crew members to easily slide past, 

and the Wide Guard is excellent for wide cockpits or where the 

pedestal is located against a bridge deck. It affords extra pro- 

tection on those boats with a main sheet or traveller just for- 

ward of the pedestal. Both Narrow and Wide Guards are also 

available for the bridge deck or seat risers. These offer an ex- 

cellent hand hold when coming up out of the companionway or 

stepping athwartships. Edson guards are also excellent for 

mounting binocular holders, teak cockpit tables, winch handle 

holders, and cockpit umbrellas. 


When ordering Pedestal Guards specify pedestal size. Size 

45 guards fit Fig 334141' and Fig 335-5" Steerers, and Fig 317-4" 

and 5" Compass Pedestals. These measure approximately 

6-7/8"119.5cm across the top of the bowl. Size 6 guards fit Fig 

400 and 420-6" Steerers and Fig 317-6" Compass Pedestals. 

These measure approximately 8"/20.4cm across the top of the 

bowl. -.

' hake Plate-, - WRAP AROUND FRICTION BRAKE FOR PEDESTAL STEERERS 

The most popular accessory for all steerers. 

Brakes are designed to dampen the action of the 

wheel, especially handy on long runs orwhen operating 

under power. Can also be used to hold the boat on 

course under most conditions while the helmsman 

trims that sheet or goes below. As a safety feature, 

the brake can always be overridden by the helmsman. 

All mounting holes in the steerers are predrilled 

at the factory, allowing simple installation in 

about 15 minutes. Brakes are constructed of bronze 

with long lasting brake lining, and supplied with 

stainless steel shaft and shiny black brake handle. 

The handle is designed to "pop" if a line gets tangled, 

an added safety feature. When the boat is unattended, 

secure the wheel with the brake. In rough 

weather, the rudder can swing violently from stop to 

stop causing damage. Note: If you do not own a 

,

Ordering Information 

When ordering a luncheon table, dining table, or "Hardware 

Only" kit, note that each table is designed to fit two different size 

pedestal guards. Measure the distance between the centers of the 

guard pipes to determine which size you need. The figure number 

designates the style table you choose, the size tells what size 

guard you wish to install it on. Please refer to the guard sizes 

listed below.

24%-.----+ With the ever increasina number of sophisticated instrcl Qx 

I 1 ments on the market today, the question of the location of' 

these instruments has become of prime importance to the 

boat owner. The latest trend of mounting the instruments 

on the steering pedestal has several distinct advantages: It 

provides for a neat and,efficient steering area, the helms- 

man has an unobstructed view of the instruments, the in- 

struments become more serviceable, and, of course, it no 

longer becomes necessary to drill and cut into the boats 

deck house. 

Edson has now designed housings and pods for one, two, 

three or four Pedestal lnstrument Displays. All are designed 

with the Edson Pedestal Guard which not only protects the 

crew and the instruments but in turn permits the owner to 

have a table and other pedestal accessories. These Guards 

are positioned 4" forward of the pedestals to allow the top 

housing or pod to be well forward of the compass lubber 

line: this aives the helmsman a clear view of the compass.

Edson's pedestal controls are available for most all popular 

marine engines. These controls can be neatly run inside the 

pedestal column or they can be externally mounted for those 

who appreciate an easy installation, and like to have the heart 

of the controls openly available for continuous visual checks. 

All models feature the safety of clutch and throttle handles 

protected between the pedestal and the steering wheel. This 

prevents accidental shifting of the engine by an unsteady 

crew member, and keeps handles clear of the main and genoa 

sheets. All control handles are conveniently located so the 

helmsman does not have to look away during important dock- 

ing and close maneuvering situations. Athwartship handles 

allow easy installation on most transmissions, including 

A THI!O,~T.LR~ 

Both push-pull cables are run neatly within the pedestal, well 

away from the steering chain and cables. The increased lever- 

age allows effortless shifting, and throttle control with one 

hand always leaving the other available for steering. Built in 

handle stops prevent cables from fouling in the steering chain 

and cables. Note how neatly the 10" long Clutch Handle is 

tucked between the wheel and the pedestal. That is why Edson 

calls it a "Safety Handle" - it is out of the way of snagging 

lines, and possible unsteady crew members. The mechanical 

shift provides an extra throw (Max. 3-318") for particularly diffi- 

cult to shift engines. Weight 4 Ibs.ll.8k.

INTRODUCTION 

The following four pages cover the latest addition to the Edson 

Family - the Pull-Pull steering systems. These systems are adapt- 

able to power boats, midship and aft cockpit sailing craft. Basically 

thesystem is used in conjunction with apedestal or bulkhead steerer 

and theconduit takes the placeof sheaves.Theverysimplicity of the 

installation makes this method of steering very appealing. 

The Pull-Pull conduit is made with an inner core of polyethylene 

which is covered by many strands of steel wire. These wires are 

then wrapped with aflat wireand thewholeassembly is then sealed 

by a plastic cover. The steel wrapping gives the conduit that extra 

strength and is exclusively an Edson feature.The conduit comes to 

Edson from the aircraft industry and has been successfully tested 

to 600,000 cycles without failure. The Edson Figure 827 Lubricant 

(which is used in maintaining the Pull-Pull system) is an inert base 

oil combined with Teflon and is an important addition as it reduces 

friction bv about 30 oercent. 

The conduit can snakearound obstaclesorpass neatly through a 

cabin area or over and around a tank heater;exhaust line. In effect, 

we recommend Pull-Pull where straight; line sheave to sheave 

wheel cable systems are difficult to fit. We find that on many pilot 

house boats with dual steering stations that the aft steerer will be 

all sheaves, but the forward station will use a combination of 

sheaves and Pull-Pull conduit. The conduit will be used fora length 

of 8 to 10 feet as it snakes down the interiorwhile going upand over 

and down an obstacle and then into a Radial Drive or other sheave. 

SAILBOAT INSTALLATIONS 

On the following pages we are showing the various methods of 

installing the conduits as well as the different specialized hardware 

designed by Edson to make the installation easierand also to allow 

for easier maintenance and inspection of the completed system. 

As in all steering systems, the basic setup should be made to use 

as many of the existing structural members as is reasonably possi- 

ble. If a bulkheadcan belocated to serve as an anchoring point for 

the conduit or one of the new conduit sheave assemblies, so much 

theeasier. Needless tosay, the bulkheads must bestrong and up to 

the steering loads that will be put upon them. 

The aft plywood gussetts must'be adequately reinforced to accept 

theend fittings of the conduit. An easy way to locate theend fitting 

is by placing a% inch dowel or rod in the groove of the quadrant and 

at 90 degrees to the centerline go to the gussett which is fore and 

aft and drill a 'la inch hole for the conduit end fitting (see illustration). 

With the dowel in the other groove of the quadrant, drill the opposite 

gussett for the opposing Pull-Pull conduit. 

If there are no gussetts opposite the quadrant radius, the Figure 

824-17 Bracket can be used as it can be bolted to a flat surface 

either parallel to the top of thequadrantwith thestop pointeddown 

or on a flat parallel surface directly under the quadrant. This bracket 

must be carefully located and well bolted down as the stop pin 

must hold the expected rudder loads in the hard-over position. 

For complete warranty information - see inside front cover.

The easiest of all methods is that shown here, that of takina a 

bulkhead steerer on either power or sailboat and run it out around 

TYPICAL OUTBOAR 

Pull-Pull easily adapts for use with outboard rudder boats as 

shown, cables run beneath the sail locker on one side and under a 

quarter-berth on the other. 

Pull-Pull is shown here in a particularly complicated aft-cockpit 

arrangement. This illustration shows the Pull-Pull conduit being 

run between quarter berths and around a tank where wire rope and 

sheaves would be very difficult to insta

PULL-PULL STEERING SYSTEMS

;w' MIDSHIP COCKPIT INSTALLATIONS 

Shown on this page are the two most popular methods of run- 

ning the Pull-Pull conduit in a mid-ship cockpit installation.The top 

drawing shows theconduit running down the starboard sideof a37 

footer, the end fittings of the conduit are attached to the gussetts 

or reinforcing that is normally located below the aft bunk. This type 

conduit can run through a sail locker, or in a hanging locker, as the 

wire is totally encased and there is no chance of the moving wire 

catching or jamming. Being conservative, we have limited the Pull- 

Pull to boats 42 foot or less as we feel that long lengths of conduit 

would reduce the sensitivity of the steering. However small sections 

of Pull-Pull conduit can be used on any size boat. In our continuing 

program of development these systems have been experimentally in- 

stalled on several 48 foot motor-sailors with excellent results. 

The next drawing shows a very popular method of running the 

conduit, that of straight down the center of the boat and then up to 

two of the new sheavelconduit idlersand then into thequadrant. As 

can be readily seen there are two lengths of conduit that carry the 

steering cables from the pedestal down and aft past the engine, 

and they are terminated at a strong bulkhead alongside the propellor 

shaft. There are then free lengths of wire that go aft to an area 

just forward of the rudderpost and the conduit is again used. This 

aft conduit need normally only be 3 or 4 feet.in length and would 

lead the steering wires up and out to two sheavelconduit idlers and 

then 90 degrees into the quadrant. 

With two seperate conduits per side the cost is reduced, the friction 

of excessive length is reduced, and maintenance is made 

much easier. 

Also shown is a very popular 36 foot Pilot House Sloop using a 

combination of sheaves and conduit to give a good versatile.system. 

The forward steering station uses an Edson Figure 338 Bulkhead 

Steerer going down to a Figure 625 Idler and then aft. Part way 

,-- back two 8 foot lengths of conduit allow the wire to go up one and 

down the other side of a tank; this run eliminates eight sheaves at 

' p' 

this point.

PULL-PULL INSTALLATION INSTRUCTIONS 

This section of the catalog has been designed to assist the in- 

staller with the proper layout, adjustment, and installation of this 

equipment. Please read this carefully, and go over all of the many 

drawings with the idea that each one will contribute to the end 

design and layout. 

1. Unpack everything and layout on the floor the basic arrangement 

of the system. ~akesure you fully understand the use-of 

all components and their position within the system. 

2. Locate and fasten the steerer in place, be it Pedestal or Bulkhead. 

Place the appropriate conduit holding method in place 

underthe steerer and attach the conduit to it. Make sure that the 

holding device is far enough from the steerer to allow the roller 

chain to travel its full length without the chain ends hitting the 

conduit, (usually 65 degrees to 85 degrees Rudder Travel). 

3. Place the Quadrant or Radial Drive on the rudder post in a location 

where the conduit can be aimed directly at the proper 

groove.This adjustment can be assisted by using a3!s inch wood 

dowel or equivalent. Place it in the groove and aim it from the 

centerline of the boat to theappropriateattachment point of the 

conduit. In the case of Radial Drive, the two conduits can be 

within afew inchesof each otheras long as they lead in astraight 

line to the groove. 

Make sure that the correct lead is going to the correct side of 

the QuadrantlRadial to get directional steering. Keep the conduit 

bends as generous as possible with no less than an 8 inch radius. 

4. With the system in place install thewireand chain in thesteerer 

and conduit. Place an adequate amount of the Figure 827 Lubricant 

on the wire as it is slid into place. Make sure the wire is precleaned 

of grit and that the end has no wire burrs that could 

damage the inside of the conduit. Fasten the wire to the Figure 

618 Takeup Eye and tighten so the chain is centered as the rudder 

points dead ahead. 

MAINTENANCE 

1. The roller Chain should be oiled (not greased), the steerer bear- 

ings oiled if bronze and greased if Needle Bearings. 

2. Although theTeflon grease is "trapped" within theconduit, the 

wire is out of sight and should be inspected at least oncea year 

and re-lubricated more often if the boat is contemplating an off- 

shore or lona distance cruise. After five years the wire should be 

replaced an; the old wire kept for spares if it is in useable form. 

The steering is the one piece of machinery used all of the time 

that the boat is away from thedock. Most of the "horrorstories" 

that are heard regarding steerers is one of unfamiliarity of the 

system combined with lack of maintenance. With a well designed, 

well maintained steerer the boat should be a lea sure to all.

AUTO-PILOT STEERING SYSTEMS ./ .. 

When planning your steering system it is best to think ahead. Auto-Pilots are more popular than ever and easier to install. Edson nas 

developed three basic methods of attaching auto-pilots. first - all Edson Bulkhead Steerers, Rack and Pinion and Worm Steerers can have 

auto-pilots attached directly to the wheel shaft extension or the wheel shaft itself -nothing extra to purchase. Second - the use of the 

Edson Figure 320 Auto-Pilot Drive with the addition of one or two sheaves and the appropriate roller chain can adapt virtually all Edson 

Pedestal Systems to Auto-Pilot attachment. With the 320 the boat can use an extra quadrant or radial drive for a completely separate system 

or can introduce the 320 in to the basic wire system. Third - the all new Edson "Rapid Drive" for a right angle gear box drive - the simplest 

system for owner, yard, and boat builder. 

As a general guide the simpler the system the better. On any installation 

involving electricity the area must be well prote~ted from moisture and the 

wires used must be of the correct size and used with good solid terminal 

ends. At no time can the unit be exposed to salt water such as would occur 

if the electrical panel was placed below a sail locker. As obvious as this may 

sound we still see many units so mounted. The compass unit must be kept 

away from the boat's navigation compass as well as from other interferences 

such as an alternator on an engine. 

Take the Fig. 320 Pedestal System first. There are two basic concepts that 

can be used in the installation of an automatic oilot with a oedestal. One is 

to place the Fig. 320~uto-pilot Drive Unit withinthe boat's existing steering 

system. This would be as in illustrations 1 and 2. A second method would

or radial drive can be placed above or below the regular steering system's 

quadrant or radial drive and in the case of the quadrant on either the forward 

or aft side or for that matter on a fore and aft plane. The ultimate choice is 

determined by where you have room for the actual pilot. 

TYPICAL AUTO PILOT ARRANGEMENTS 

NOTE: See Midship Planning Page 44 for more auto-pilot arrangements. 

WORM STEERERS 

Worm Steerers can have the Pilot Sprocket 

on the aft extension or between the rudder- 

ost and the aft side of the wheel. Before 

guilding the boxlcover you must first 

establish the size of the sprocket that is 

furnished by the pilot manufacturer.

ORDERING INSTRUCTIONS - 7 " L, y- 

When planning an Auto-Pilot System you must furnish the pilot manufacturer the number of turns hard over to hard over in 90" in your steer- 

ing system so they can recommend the proper size drive sprocket. The number of turns and length of roller chain for a given size quadrant or 

Radial Drive is shown in the selection chart for each type steerer. In the case of conversion to a pilot hith a pedestal, it is necessary to pur- 

chase the following items: 1) Fig. 320-Size 2 Auto Pilot Drive Unit, 2) an appropriate length of 5 /~" Roller Chain, Fig. 630s. The length is determined 

by the quadrant or Radial Drive size to which the pilot is to be attached. This should be accompanied by the necessary wire rope, roller chain, 

master links, end fittings, and the necessary extra sheave or sheaves to accomplish the installation. Be sure to use the same size sheaves as 

are in the regular steering system for the boat.

RAPID DRIVE 

A MEW CONCEPT IN AUTO-PILOT STEERING 

Rapid stands for Rack and Pinion Independent Drive and incorporates the 

latest in engineering from Edson. Rapid is adaptable to virtually all types of 

boats be they power or sail with wheel or tiller. The steering system must 

be of the easily reversing type or in the case of a Hydraulic Steerer be 

capable of being totally bypassed. The unit attaches directly to the rudder- 

post of the boat and the frame of the Rapid bolts to a flat platform 90" to 

the rudderpost. The auto-pilot attaches to the Rapid unit with conventional 

sprocket and chain reduction and with Rapid Drive there is no need for 

additional rudder stops except in the case of tiller steered conversions. 

Precision cast bronze aears orovide effortless ooeration. without notice- 

able friction or noise. hi unit'operates withl.8tu;nsof the shaft in 80°0f 

rudder travel; your Auto-Pilot manufacturer will specify the sprocket sizes 

when you order the pilot. 

One of the Edson Rapid Drive features is its compactness. As noted on 

the dimensional drawing, the unit takes up only a total width of 191h inches, 

and a fore and aft dimension of 11" plus the 3" shaft extension. When 

ordering your Auto-Pilot, please note that the shaft for the sprocket is 1" 

with a lh" keyway. Maximum Input Rating of the "Rapid" Drive is 1,000 

inch pounds based on a%" #41 ten tooth power unit sprocket. 

One of the variations of the unit is the Fig. 319 Rapid Drive which in- 

corporates the universal and an extra self-aligning bearing. This unit allows 

either the basic Rapid Drive to be mounted other than fore or aft and to angle 

the shaft extension to facilitate locating the actual Auto-Pilot. The illustra- 

tions below show some of the many variations available when using 

Rapid Drive. 

ORDERING INSTRUCTIONS 

Rapid is available in 6 sizes for rudderposts of various sizes. When order- 

ing it is necessary to specify the rudderpost bore, keyway size and its 

position, that is on the geared segment side or the cap side. The geared 

segment can also be attached by pin or set screws. For these methods 

pplease see the quadrant page of this catalog. Be sure and specify your pre- 

e r r e x h o d .

For Fig. 318 and 319 the following sizes apply: 

Size 2 1/2" to 1-3/16 Rudderpost Size 

Size 4 1-1/4" to 1-13/16" Rudderpost Size 

Size 6 1-7/8" to 2-511 6 Rudderpost Size

Size 10 2-7/8 to 3-1./2 Rudderpost Size 

Size 14 3518" to 5" Rudderpost Size 

Weight: 19'hlbs. 

The Rapid Drive and the Auto-Pilot must be securely held to a platform. The electrical wirGg to the Auto-Pilot must be of the size recom- 

mended by the Auto-Pilot maker and fastened with good solid terminals. The installation must be protected from moisture. As in all exposed 

gearing the Rapid must be covered by a clear Lexan or equivalent cover to keep equipment and fingers out of the mechanism. The clear cover 

permits ready visual inspection. Maintenance of the Rapid is simple - use #30 or equal Motor oil on the shaft bearings and on the geared 

segments and wipe across the bottom of the segment. Water pump grease can also be smeared on at this point. The unit should be inspected 

like all steering equipment and it is wise to checkand oil it at least once a week.

chosen wheel size. At the same time the area below the cockpit 

floor should be checked for obstructions such as tanks, lines, etc. 

and also to check to see if the builder installed cockpit floor reinforcing 

and its exact location. The location of the winches and the 

helmsman's visibility should also be noted. 

\y&g' 1 lllustration 1 Forward Position 

lllustration 1 shows a steerer forward using Radial Drive. By plat- 

ing the steererat the forward end of the cockpit the helmsman has 

the protection of the companionway dodger and has quick and 

easy access to the cabin below. The forward location also keeps 

the cockpit activity aft of the helm and when in shorthanded situa- 

tions allows the helmsman to steer and handle the sheets with the 

minimum of difficulty. Edson suggests using a large size wheel 

within 2" or 3" of the cockpit seats if the boat has a bridge deck, 

as there will be no need for guests or crew to "slide" by the wheel. 

We also recommend the installation of a pedestal guard as a hand- 

hold for crew members going below. The larger wheel will allow 

the helmsman to comfortably lean against the coaming and to 

have excellent all-around visibility. In many conversions from tiller 

to wheel the forward locations makes for the least cockpit layout 

change as it places the helmsman in approximately the same loca- 

tion with the wheel as with the tiller. For a racing boat all the ac- 

tion is aft and when not tacking the crew can sit to weather and 

forward if it improves the balance of the boat. 

TYPICAL OUTBOARD 

RUDDER INSTALLATION 

Pull-Pull easily adapts for use with outboard rudder boats. As 

shown above, cables run beneath the sail locker on one side and 

under a quarter-berth on the other. 

lllustration 3 shows a pedestal steering installation on an average 

25 to 30 footer with transom hung rudder. The Edson Fig. 612 *I1 

Quadrant series can be used on most all boats of this design. \i- 

The quadrant should be mounted fairly high on the rudder to fit 

within the lazarette, or so a box or helmsman's seat can be built 

over it as illustrated. 

As a rough guide to the following Fig. 612 Quadrant sizes should 

be used. 

Boat Length: 20 to 36 feeff6-11 m. . . . . . . . . . . . .I0 inch size126 cm

45 to 60 feeU14-18 m. . . . . . . . . . . .20 inch size150 cm 

The above chart must be used with caution, obviously a very hard- 

to-steer boat must go to the next size larger quadrant than is in- 

dicated. With all Edson Pedestals the quadrant size in inches is 

roughly equal to tiller length in feet. As in any opening in the tran- 

som, it must be booted or a drain pan or area must be installed to 

prevent water from getting into the structure of the boat. As a fur- 

ther guide the 10" quadrant requires a transom hole of about 2"/5 

cm by 6"/15 cm. 

MID-COCKPIT POSITION 

Placing the steerer in the middle of the cockpit or within two feet 

of either end can give a good balance. The crew can be forward or 

aft whichever makes the boat go best. With the steerer in the rela- 

tive center of the cockpit the spinnaker winches can be aft and the 

genoa winches forward; when racing this keeps the spinnaker ac- 

tion behind the helmsman and yet allows the helmsman to assist 

with the jib winches if needed. When cruising the mid-cockpit 

arrangement enables the guests to relax aft and not get involved 

in sailing the boat while the skipper can steer and tack the boat 

with ease. 

i- ' 

When placing the pedestal at mid-cockpit keep at least 15"/38 cn IP', 

clearance from the bridge deck or companionway. This will p rew" 

vent a crew member from having to stand with one foot on the 

bridge deck, a dangerous'off-balance situation. The helmsman 

normally will sit to one side of the wheel or stand behind the 

wheel. Edson's Helmsman's Seat can fit neatly between the seat 

risers and its arched center section raises the helmsman for bet- 

ter visability.

AFT COCKPIT STEERING (Continued) 

lllus tra tion 4 

lllustration 4 shows pedestal in mid cockpit using Pull-Pull shown 

in a particularly complicated arrangement. 

This illustration shows the Pull-Pull conduit being run between 

quarter berths and around a tank where wire rope and sheaves 

would be very difficult to install. 

The aft location of the wheel in a long narrow cockpit is the traditional 

location of a pedestal. The helmsman can see all of the action 

and if a line jams or some other problem develo~s he can take 

the best corrective action. if the steerer is well aft it'is a good idea 

to put on the narrow pedestalguard and for the engine controls to 

be placed on the steerer. When planning this installation beware 

of such potential problems as a tall helmsman's head hitting the 

backstay or the possibility of the main sheet catching the pedestal; 

also be certain you have enough space, (at least 16"141 cm) 

clearance behind the wheel to allow foot room at the helm. At Edson 

we can always tell when a pedestal is too far aft; there are heel 

marks on the end of the cockpit where the helmsman has tried to 

move his feet aft and found no space. 

lllustration 5 shows a cockpit with the steerer aft and in this case 

a separated helm. Note that all of the steering mechanisms are 

within the cockpit bridge. The quadrant is mounted on the aft side 

of the rudder post which necessitates crossing the cables within 

the pedestal. 

(3 

Note the Fig. 727Safety Clutch can bring the control cables down 

just aft of the bridge deck so they lead directly to the engine and 

do not get involved with the bridge deck and the moving quadrant. 

lllus tra tion 6 

lllustration 6 shows the rudder post forward and the steerer aft. 

Note that the wires can run forward or aft to the quadrant. If the 

steerer is placed up against the rudder post the forward side of 

the base can be "Milled" off to gain space. 

With the helmsman aft all of the crew is forward and they must 

handle the sailing of the boat as the helmsman can not contribute 

any reasonable assistance. This is usually no problem on a 45 

footer that requires a larger crew but on a 35 footer or less it can 

present problems. However, when cruising this can be an advan- 

tage since the skipper can supervise sail handling and keep track 

of children and guests. 

lllustration 7 

In lllustration 7 the rudder post is vertical and there is a quarter 

berth on the port side aft. The solution was to mount the quadrant 

angled to one side and to lead one of the wires directly into the 

quadrant and the other aft to a sheave and back into the quadrant. 

As a matter of interest one of the earlier boats on which this was 

done was a 36 footer. The idler sheaves were 4"/10 cm as the wire 

only went around the idler sheaves 90 degrees. On the aft single 

sheave it was 6"/15cm as the wire goes around it about 180 degrees, 

the larger sheave will increase the feel of the rudder from 

reduced wire friction. 

GENERAL 

As in all installations, Edson tries to reduce the number of 

sheaves. They must be bought, installed, and each one adds its 

friction effect. A good "needle bearing" pedestal with as few 

sheaves as possible with well oiled bushings and a well hung rudder 

will give a very sensitive system and one that is free of problems.' 

The "T" Cockpit can have the steerer placed aft (pictured) so the 

helmsman is sitting on the aft seat and sliding around to the sides 

or another variation would place the pedestal well forward in the 

cockpit and bring the primary winches aft by the base of the "T" 

so the winch grinders can stand by the handles. Likewise, down- 

wind under a spinnaker it would give the sheet handlers more 

room and hopefully less chance of error. 

One distinct advantage of the aft steerer arrangement is that the 

helmsman can see all that is going on in the cockpit, an important 

factor when racing. When the steerer is placed at the extreme aft 

end of the boat be sure that the jib luff can be easily seen and it 

not being visually blocked by the main. 

Please remember that fiberglass by nature is flexible material and 

the steering system must be set up so it is strong yet can stand a 

certain amount of movement. The smoothest installations are 

those with the best reinforcing - "There's a message." 

If you have plans or ideas that you feel would be helpful to other 

boat owners please send them to Edson and we will pass them on 

to all our customers.

ship cockpit boat, the steering system should be thought 

out at the time the boat is designed or at least before the 

interior is in place. There are virtually no boats that can not 

be adapted to a wire system. 

Whichever system used, the advantages of a wire system 

are many and important. The system is simple; this makes 

it excellent for those boats going off-shore or to remote 

areas. A roller chain pulls the rudder to one side or the 

other. If the wire fails you can rig a new wire. Try that with 

other types of steerers. It is in effect a screw, nut and bolt 

philosophy of design. 

The steering will give the boat a personality. There is feel, 

response, flexibility and if you want to settle down, put on 

a dampening brake, add a simple mechanical Auto-Pilot. 

These will give you the best of all worlds. 

PLANNING FOR THE WIRE ROPE SYSTEM 

lllustrations 2 and 3 show the most commonly used 

method of runnina - the wire in a mid-ship Cockpit Boat. 

The wire is run to either the port or starboard side by using 

the Edson Fig. 607 Adjustable Idler. This directs the wire 

aft a small amount, down a small amount to double 

sheaves that are mounted on the aft engine room bulkhead. 

Care must be taken to make sure that the wire is clear of 

the - aoorooriate .. sail lockers.

The wire is then directed aft at a level just under the bunk 

top and on the outside of the backs of the drawers in an 

area aenerallv considered to be otherwise unusable. In 

manvcases the wire is run alona - the exhaust line trunk. 

Aft the two sheaves are mounted on a stiffening bulkhead, 

one sheave leads the wire directly to the quadrant, the 

other sheave across the boat to a sheave and then back to 

the auadrant. Care must be taken to make sure that the

connecting rods. 

lllustration 1 shows two basic methods - we will call them 

port and starboard for the sake of simplicity. 

Starboard - The wire is led to starboard just under the 

deck level, over the heads of those passing through the aft 

cabin passage. The wire is then led aft just inside of the

ENGIINEERIING AND 

lllustration 3 shows another form of placing the Pedestal in 

the Mid-Ship Cockpit Boat. The wire is basically led down 

and run beneath the aft cabin sole. 

The Pedestal can be placed aft in the cockpit with the pos- 

sibility of placing the helmsman on a raised seat for better 

visibility over the house. 

MlDSHlP COCKPIT STEERING (Continued) 

lllustration 3 

This installation assumes the engine is directly below the 

Pedestal and it is necessary to place Fig. 607 Adjustable 

Idler under the pedestal to direct the wire aft a small 

amount. The sheaves at the floor level can be placed on the 

very aft end of the engine compartment and they in turn 

will lead aft to two sheaves placed on a transverse bulk- 

head directly under the aft cabin floor. These in turn direct 

the wire aft, up and out to two sheaves mounted on the 

'Ounk front bulkheads and then directed into the quadrant. 

Emergency steering can be placed on top of the rudder 

post by simply removing the aft cushion and by placing a 

tiller at this point. Some owners prefer an extension that 

goes through the aft deck to allow placing the tiller over 

the aft deck house. This is a personal preference, but by all 

means have an emergency method of steering. 

The lllustration 4 installation is used on boats with 

passage ways, toilets or lockers on both sides of the cock- 

pit foot well. With this layout one way to steerthe boat is to 

run the wires under the floor of the aft stateroom. 

The Pedestal can be placed at the point up against the 

ridge deck or in the normal aft position in the cockpit. If 

laced forward it does allow the helmsman to be protected 

Qn poor weather by the dodger. In addition, the engine con- 

trols and instrumentation can all be mounted on the aft end 

of the house. This can then place all of the wiring in an 

easily accessible trunk within the main cabin. 

The wire from the pedestal goes down and is "Veed" slight- 

ly to allow the wires to go to sheaves fastened to the engine

the natural "V" of the hull. Aft to two sheaves which can be 

placed on a simple structure and then out and up to two 

sheaves and then into the quadrant. Note how the sheaves 

can be fastened to existing bunk fronts andlor bulkheads. 

Very important to keep costs in line as well as to keep the 

structures simple. . 

PLANNING FOR THE PULL-PULL SYSTEM 

Edson's new Pull-Pull Steering System is ideal for mid-ship 

cockpit boats up to about 42' in length. The Pull-Pull Sys- 

tem is an alternative to the standard wire rope and sheave 

installation. The following illustrations show just a few of 

the many uses of Pull-Pull Steering. 

lllustration 5 shows a Destroyer Wheel with a Fig. 338 or 

410 Steerer mounted in a cockpit moldment. The moldment 

houses engine instrumentation and controls while serving 

as a table for cockpit entertaining. Since the quadrant is 

mounted on the aft side of the rudderpost, the cables are 

crossed within this structure for proper steering direc- 

tion. 

In this case, one cable runs along the port side to the quad- 

rant while the other cable runs directly down the starboard 

side. With this type installation, the cables can be anchored 

to an existing moldment or plywood reinforcement. Here, it 

is attached to the plywood reinforcement normally placed 

under aft bunks. 

lllustration 6 shows the Pedestal installation using the 

841 Mounting Plate for attaching the cable. The cable is 

routed along the starboard side under a bunk to a Radial 

Drive. One wire can run across to a sheave mounted on the 

other side and back into a regular quadrant if space does 

COMBINATION PULL-PULL CABLE AND SHEAVES 

lllustration 7 shows the cable running down, over the 

engine, and aft under the cabin sole. With the sharp bends 

aft, the system converts to a standard wire rope and sheave 

arrangement connected to a quadrant or Radial Drive.

PEDESTAL STEERER INSTALLATION INSTRUCTIONS PEDESTAL STEERER INSTALLATION (CONT. ) 

INTRODUCTION 

This section has been prepared for both amateurs and professionals 

to assist in the installation of the Edson pedestal steering 

systems. We have tried to take the installation step by step in 

hopes the job will not only go faster but also much easier. You will 

find many suggestions along with simple illustrations to guide 

you - but in the marine trade there is always an experience factor 

which cannot be covered on paper. If you require assistance or 

additional information write or call The Edson Corporation. We 

offer complete engineering services at no charge or obligation. 

Edson has over 1,000 installation drawings which we call S-data 

sheets. If you own a stock boat, feel free to request a data sheet on 

that boat, or if you are building orpurchasing a custom boat, send 

us a print, or good sketch and we will be glad to send you a com- 

plete proposal and a data sheet on your boat or a similar installation. 

LOCATION OF PEDESTAL STEERER 

After carefully unpacking the Edson equipment, lay out all the 

components and familiarize yourself with the system by arranging 

the parts as closely as possible to the order of assembly. 

From the architect's drawing or the boat's data sheet find the ideal 

location for the installation of the pedestal steerer. 

Set your pedestal, with the wheel attached, at this position and 

check the cockpit layout. Will you be able to crank your winches? 

Sit and stand comfortably? Will the main sheet clear the wheel? 

Adjust your steerer until you are satisfied you have the best location 

possible. We suggest at least 21 "154cm from the pedestal base 

(dead center aft to the rear of the cockpit for standing room). 

Now check the area under the cockpit floor to make certain the 

pedestal location chosen will allow freedom of installation for all 

the components. 

With the pedestal carefully aligned fore and aft and centered, use 

Edson's Template EB237 furnished with each order to mark the 

location of the four bolt holes. At the center drill a thru hole 

%6"/7.5mm dia. This tiny hole will mark the pedestal location when 

working under the cockpit floor. Do not drill any other holes at this 

time. (The small hole can easily be filled should you decide to relo- 

cate the steerer.) 

PREPARATION OFTHE RUDDER POST 

If you are ordering a new boat with a tiller but plan to add a pedestal 

steerer at a future date, have your boat builder install a stuffing box 

and key the rudder post. This can be done by the builder at a 

nominal cost and will make the steerer installation far easier for 

you when the time comes. 

If your boat's rudder is equipped with a stuffing box the Edson 

PedestalSteerer may be installed with the boat in the water. 

If your rudder post enters through a fiberglass tube from the hull 

to the floor, a portion of this tube will have to be cut away to expose 

the rudder post for the installation of the Radial Drive Wheel or the 

quadrant. Although Edson recommends a stuffing box, some boats 

with high enough freeboard can do without one. A stuffing box 

must be installed if the cut is less than 12" to 15" above the waterline 

and the boat should be hauled for this operation. Where the 

cut will be made is determined by the location of the Radial Drive 

Wheel or auadrant and the size of the idler sheaves (see Figs. 1 

and 2). ~easurefrom under the cockpit floor either 5"112.7& or 

7"118cm down depending on your sheave size. This locates the 

wire groove in the Drive Wheel or quadrant. With a square mark its 

location on the tube. Start measuring from this mark. 

For a quadrant installation measuring up 2"138mm then down 7"l 

17.8cm. 

For Radial Drive with the hub up measure up 4"IlOcm and then 

down 8% "120.9cm. 

For Radial Drive with the hub down measure up lr/z"/38mm and 

then down 9"122.8cm. Mark the lines and cut the tube at 90".

There are three methods of preparing and attaching the Radial 

Drive wheel or the quadrant to the rudder post. The most secure 

method for solid stock is cutting or milling a keyway in the rudder 

post, and the drive wheel or quadrant. Be sure and cut the keyway 

longer than necessary for final adjustment, and the possible 

addition of an autopilot.

A suitable stuffing box should be used to seal the rudder post at 

the tubing. Edson's Fig. 697 Stuffing BoxlBearing is preferred, as it 

serves as additional bearing, however, hose type stuffing boxes 

may be used. Edson stuffing boxes are available for rudder posts 

from l"12.51cm diameter 31/~"/8.9~m diameter and are approximately 

4"170.2cm in length. The stuffing box must be installed 

' '' 

above the water line. It mounts on top of the lower cut in the fiberglass 

tube (see Figs. 1 and 2) and is heavily wrapped with fiberglass 

and epoxy resin. As on all rudders be sure and place the Fig. 697 

Stuffing Box within about 11/z"l3.8cm of the bottom of the quaddrant 

or Drive Wheel and supbort it well for the rudder loads. Figs. 

1, 2, 6, 7 and 8 show typical stuffing box arrangements. With the 

rudder post back in the boat, place the drive wheel or the quadrant 

onto the post at the determined position. NOTE: As a simple 

safety factor, install a stainless steel hose clamp directly under 

the quadrant or Drive Wheel. This will prevent slippage if the 

quadrant or Drive Wheel were to loosen in service.

separate instructions covering Fig. 10. All other installation pro- 

cedures are the same. 

RADIAL DRIVE INSTALLATION 

Alignment between the idler and the Drive Wheel is done by rais- 

ing or lowering the Drive Wheel on the rudderpost. Be sure and 

cut the keyway longer than necessary for final adjustment. When 

locating the keyway, decide whether you will be mounting the 

Drive Wheel hub up or hub down, because the wire line is not at 

the center of the hub. Cable tension is adjusted using 2 Fig. 618 

Wire Rope Takeup Eyes as in the standard quadrant system. 

On pedestal installations, with the rudderpost raked forward or 

aft you may require a block of wood between the cockpit floor and 

the idler to lower the idler for a good lead to the Drive Wheel. An 

alternative, sometimes used on racing yachts for ultimate feel, is 

using a6" idler to lower the wire lead. 

PEDESTAL SUPPORT The Drive Wheel is supplied with a welded steel rudder stop 

On many boats the cockpit floor will require "beefing up" at the 

pedestal, one method is to install a piece of 1/2"113mm to 3hr' 

19mm plywood about 2 feet square under the cockpit floor (see 

Fig. 9).

GLASS PLACE IN WOOD SUPPORT 

FIG. 9 

The wood should be securely fastened by glassing in with epoxy 

resin and several layers of mat (fiberglass kits are available from 

your local marine dealers). The strain of a pedestal steerer on the 

cockpit is severe and we recommend this type of suppart. The 

wood support also makes a smooth working surface for mounting 

the idler sheaves. On a wood boat a well seasoned blocking should 

be installed between the beams under where your pedestal will 

mount. If your cockpit floor is rigid (no flexing or oil canning effect) 

and is fairly smooth on the underside you can eliminate the 

extra support.

POSITIONING THE IDLER 

Whether installing a Fig. 776 Idler, 71 1 Idler, or a Fig. 842 Dropped 

Conduit Mounting Plate, at the previously marked location for the 

pedestal, drill four holes through the cockpit floor. At this time 

saw or drill one5" diameter opening. This eliminates the necessity 

of drilling four separate holes when using Edson Engine Controls 

andlor the optional instrument pods. Secure the idler in position 

with the pedestal bolts, and temporarily adjust the angle of the 

idler sheaves. 

which can be mounted above or below the Drive Wheel forward or 

aft. (See Figs. 27 thru 32 for installing proper stops.)

(.J~uLL-PULL INSTALLATION 

METHODS FOR INSTALLING SHEAVES INSTALLING BRACKET When installing the Pull-Pull System the two conduits can either 

1. The sheaves may be mounted on wood supports that tie the 

cockpit to the bottom of the boat and keep the steering loads from 

wracking the cockpit with resultant bending of the rudder post. 

2. The use of an Edson Fig. 739 or 740 bracket that bolts to well 

glassed in wood blocks. This system is excellent for those boats 

that have an adequate transverse bulkhead to take the loads. 

INSTALLING SHEAVE SUPPORTS 

Fig. 12 shows the time honored "Edson Method" of glassing in 

wooden sheave supports. The port side shows the wood support 

running from the inside sail locker to the bottom of the boat. It 

should be glassed or bolted and made smooth so it does not catch 

your sails. 

The starboard side indicates a modification when a quarter berth 

or other structure limits the use of the cockpit bulkhead. Here the 

sheave support butts against the cockpit floor or pedestal support. 

Use straight grained mahogany approximately 1M"x 8 and long 

enough to reach between the outboard side of the cockpit seat 

risers and the hull. Bond in place with epoxy resin and glass cloth, 

for added support we recommend a wood (same stock) spreader 

between the two sheave supports (see Fig. 12). 

POSITIONING THE SHEAVES 

., , 8 ,, FIG. 12 FIG. 13 

The location of the sheaves is crucial for any misalignment will 

cause binding in the system. The edge of the sheave which re- 

ceives the wire from the quadrant must be on tlie same plane as 

the correct groove in the quadrant (see Fig. 15). 

Simply adjust the outboard sheaves (using the "c" clamp) up or 

down until the two sheaves and the quadrant appear to be on the 

same level (see Fig 15). This can be done visually but as a check 

you can use a level or take measurements from the overhead. .

FIG. 14 

FIG. 15 

The Figs. 739 and 740 are alternative methods that can be easier 

on those boats where the cockpit seat risers are alongside the 

radius of the quadrant and the pedestal is as shown on Fig. 17. This 

system can be used interchangeably with the "Edson Method" or 

mounting wood blocks for the necessary sheave support. The 

preferred sheave bracket installation (shown in Fig. 17) uses 

approximately 2"1 5crn by 12"130cm to 18"146crn wood blocks 

glassed into the sail locker sides of the cockpit floor. When 

necessary to bolt thru the cockpit floor, keep as wide as possible 

with the bolts as near the edge of the cockpit gutter as possible. 

This reduces the chances of oil canning the floor and resulting 

cracking of the gel coat. 

FIG. 16 

FIG. 17 

Locate the bracket with the.quadrant stop inside the 90" segment 

of the quadrant. In so doing, the sheaves will automatically be 

correctly aligned with the exception of vertical adjustment. 

Although Edson has the "A" dimension for most stock boats on 

record, it is advisable to supply the "A" dimension to suit your 

own installation plan when ordering.

be routed port and starboard (Fig. 19) or both down the same 

side (Fig. 20). If space is at a premium lead both conduits down 

the same side and then route one wire across to a sheave mounted 

on the opposite side and back to the quadrant (Fig. 21). The con- 

duits must be terminated by drilling a 3hr1 hole in either an existing 

moldment or a plywood bulkhead. Anchor the conduits in place 

by using the nuts and washers supplied (Fig. 22). When terminat- 

ing the conduits make sure they lead the wire rope properly either 

to the steerer or to the correct groove of the Quadrant or Radial 

Drive. The Pull-Pull conduit has a minimum bending radius of 8" 

and for the smoothest steering try to keep the number of sharp 

bends to a minimum. Once the system is hooked up tighten the 

wire rope to eliminate all play, but do not overtighten. 

PEDESTAL INSTALLATION 

Install the pedestal as shown in Fig. 23, using four Fig. 646 

Pedestal Mounting Bolts. 

ALIGNMENT OFTHE SHEAVES 

Alignment is not difficult but must be done with care. One of the 

easiest methods is to substitute shock cord for the wire cable. 

The shock cord should go over the pedestal sprocket and 

be "fished" through the deck, the idler sheaves around the outboard 

sheaves, into the grooves of the quadrant and tied with a 

small amount of tension to the Fig. 618 Take UP . Eyes (Figs. 24 

~ . - 

and 25). 

Now adjust the outboard sheaves by angling up or down or raise 

and lower the Drive Wheel on the rudderpost to insure a fair lead 

to the idler sheaves and the grooves in the quadrant or Drive 

Wheel. When you are certain they are properly positioned you 

can permanently bolt the sheaves to their supports. Use large 

backup washers between the nut and the wood sheave supports. 

th the shock cord removed, and all the components fastened 

wn you are now ready to install the steering cable. 

INSTALLING THE CABLE 

Measure the amount of wire needed and cut off two lengths of 

stainless steel wire (7 x 19 non-magnetic) about two feet longer 

than the required length. 

dson 

Use 3hs"14.76mrn for 4"llOcm sheaves or 1h "16.35mm dia. for 

6" sheaves. Secure the roller chain adapters to one end of each 

length of wire (use non-magnetic fittings). do not use wire clamps 

as they might lock within the pedestal. Be sure the chain is 

centered over the sprocket when the quadrant is centered mid- 

ship (rudder in fore and aft position). This is important to keep end 

fittings on the chain from over-riding and damaging the sprocket. 

Lead the two wires around the idler sheaves, the outboard sheaves 

and around the quadrant to the eye bolts. (The eye bolts should be 

in a slack-off position.((Fig. 24) 

CLEVIS HEAD 

TWO WIRE ROPE CLAMPS 

. FIG 618 TAKE-UP 

When installing the Radial Drive, lead the wire rope directly from 

the idler around the Drive Wheel to the eye bolts (Fig. 25). Secure 

the wire rope with the wire rope clamps (see Fig. 24 and 25). Tighten 

up the cables with the eye bolts but do not overtighten. To properly 

tighten cables, lock the wheel in position using the pedestal 

brake, or by tying off the wheel. Cable tension is best when you 

cannot move the quadrant or Drive Wheel by hand with the wheel 

locked in place. Overtightening will greatly reduce the sensitivity 

of the system. 

With one person at the wheel and one watching the machinery, 

turn the wheel from hard over to hard over checking for any binding 

or misalignment in the system. The man at the wheel can check 

to see that the ends at the chain never reach the sprocket. 

NOTE: For RADIAL DRIVE cross the cables inside the pedestal for 

proper steering direction.

INSTALLING THE RUDDER STOPS 

PEDESTAL STEERER 

The steering system must have stops to pick up the loads at the 

hard over position. Although Radial Drive Wheels and Sheave 

Brackets are supplied with rudder stops, the preferred method 

is to install the rudder stops into the hull independently of the 

steering system. Rudder stops must be installed to prevent the 

rudder from hitting the hull or the chain adapters from damaging 

the sprocket. 

Be sure the stops are strong for they will take a lot of strain at one 

time or another during the life of your boat. The following sketches 

show the best methods of installing the stops.

INSTALLATION (CONT.) f> \, % 

All Radial Drive Wheels are provided with a rudder stop. The stops ' 

can be mounted fore or aft and to either the top or the bottom 

of the drive wheel (Figs. 27 and 30). Blocks of wood should be 

fiberglassed in place for the stop to hit. Stops must hit squarely 

and as low on the stop as possible. The best rudder stop arrange- 

ment, Fig. 37, uses a tiller arm or its equivalent as a stop. This 

keeps the stops independent of the steering. 

An alternative method for the rudder stop is to place a straight 

grained mahogany beam athwartships and cut out two notches for 

the stop to hit squarely, keeping the total travel of the Drive Wheel 

between 60 and 70 degrees (Fig. 32).//

COMPASSES AND COMPASS ACCESSORIES 

Compass, selection should be based on the size Pedestal used and the type of sailing conditions under which the compass will be used. 

For offshore cruising with long runs, a larger compass will help in steering a straighter course because of its better readability and steadier 

performance. When used at night, larger cards are also easier to read. If all sailing is done during the daytime hours or in coastal or inland 

waters where a compass is only occassionally used, a smaller compass is sufficient. Base the decision upon your requirements. If at a later 

date, a larger compass is required, the Fig 758 Compass Riser Extendercan be used to adapt that compass to any Edson Pedestal. All 5"and 6" 

compasses come complete with cylinders and domes as illustrated be low and are available either from Edson or your local marine supply 

store. The new Fig 856 Compass Adaptor also accepts a stainless steel dome. All compasses are equipped with a 5" lighted cards (12 volt DC) 

and built in correctors. The compass light must be properly wired and should be checked for the correct polarity. If improperly wired an electrical 

charge can be created within the pedestal causing the exterior coating to blister and peel. 

Note: for new compass mndels and sizes see price page.

capacities as the 117 Side lnlet Models. The pump can be 

mounted below a cockpit seat, under a berth, or beneath the 

cockpit sole at the foot of the companionway steps. It should 

be located where the person pumping can stand or sit for many 

hours without getting completely exhausted. In planning your 

installation, considerthat adequate room is given for legs, feet, 

hands, etc., so that one can brace themselves easily against 

the boat's motion. It is very important to mount the pump out of 

the way yet instantly available. The suction hose should be as 

short and straight as possible with a direct lead to the bilge 

where the hose does not need a strainer and can be lifted out 

for periodic inspection.

ADDITIONAL EDSON PARTS - If you plan upon going to sea on an extended voyage, we suggest you carry a spare Edson 

Diaphragm and a set of inlet and outlet valve rubbers as described above. Be sure you match the correct inlet valve rubber to 

the proper pump. Most Edson pump owners finds that the durable neoprene valves and diaphragm last a good many years. 

Edson's Model 100 3" Hand Diaphragm Deck Pumps are the 

highest capacity hand pumps on the market. Designed to mount 

easily and quickly on deck to a new or existing piping system, 

they are available in a 3"/7.3cm suction pipe size, or can be easily 

reduced for 21/2"/6.2cm pipe. These bottom inlet pumps will move 

45 gals.ll70L per minute or2800 gals. per hour. Suction lift is up to 

valves are clog resistant and can be cleared without any tools. Most 

~dson's Model 100 Deck Pumps come with a 48"/1.2m removable 

galvanized steel handle for that famous Edson non-tiring Lever 

Action pumping stroke. Edson's Red Seal Diaphragms are standard -- 

for years of dependable service. 

Edson's Deck Pumps are widely used on fishing boats for 

pumping and cleaning out fish holds and bilges. They are also 

perfect for oil and bulk carrying barges as routine and emergency 

bilge pumps. 

COMMERCIAL AND lNBUSTRlAL PUMPS

Edson's pumps range in size from its two inch Bone Dry Power Pumps, to 

3"/7.7cm and 4"/10.2cmHeavy Duty Power Pumps. They can be found pump- 

ing industrial waste per EPA regulations at a large factory or being used by 

the Coast Guard for cleaning up oil spills.

well as contractors, cities, municipalities, and government contracts. 

Edson's "Bone Dry" Pumps are the perfect answer for everyday boatyard 

maintenance jobs and emergencies. For pumping leaking boats Edson's 

"Bone Dry" resists clogging better than any other pump. Holding tanks, 

bilges, and holds can be pumped efficiently and quickly. Edson Bone Dry 

Pumps, pump over 50% sand and mud and are often used for light dredging 

and pile driving near piers and floats. Dig a hole with either the suction end 

or use the discharge to jet a hole for the pile. All bone Dry Pumps are avail- 

able as bronze or aluminum pumps and are available with electric, gasoline, 

or air powered units. 

For big pumping jobs Edson's Heavy Duty Power Pumps are designed to 

pump up to 8000 U.S. gallons per hour. They are self priming and non
