801 are totally assembled by Edson using
stainless steel grommets that can never
loosen from engine vibration. They are fully
adjustable and can be securely locked in
pedestal either forward or aft of the rudderpost. It is also
used for Radial Drive Steering System when the pedestal is
located aft of the rudderpost. The sheaves can be adjusted
anywhere between 6" forward to 174" aft and locked securely
in place to maintain the desired setting.

is fastened in place using the four pedestal
mounting bolts. This sandwiches the cockpit
floor between the pedestal and the idler
making avery rigid installation.For0ffshore

FIG. 776 ADJUSTABLE CROSSED WIRE IDLER is used for
those boats having the quadrant aft of the rudderpost. It is
also used for Radial Drive Steering System when the pedestal
is located forward of the rudderpost. This idler allows
crossing the steering cables inside the pedestal column to
give the proper steering direction. The sheaves are fully adiustable
between 10" forward to 170" aft and lock in place
to maintain the desired setting.

FIG. 607A or B ADJUSTABLE PARALLEL IDLER is ideal for
Mid-Ship Cockpit boats where the wire ropes can be led off
to one side of the boat and then aft. This is particularly use-
ful for running the wire rope around aft cabin passageways
or engine spaces. These two idlers are fully adjustable
through 70" arcs and will aim the wire rope in the following
direction. Assume 0" is the bow of the boat, 90" is star-

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
wheel is a "perfect circle" and dished in shape for greater
strength. Drive wheels are split in half along the athwartship

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
2 Fig. 620 sheaves for crossing the wires. Drive wheels are
available for 1 " to 4% " diameter rudder posts - Fig 777 (for
smaller bores), Fig. 800 (for larger bores).'
Note: If pedestal is forward of the rudderpost cross the cables inside
the pedestal for proper steering direction.
