36SUGGESTION AND WARNINGS WHEN SELECTING A HYDRAULIC STEERING SYSTEMHOW THE SYSTEM WORKSA hydraulic steering system consists of a steering pump, a cylinder tied to the rudder or to the outboard or sterndrive engine and theconnecting nylon or copper tubing. Under normal operating conditions, a turn of the steering wheel will pump the oil through one ofthe two connecting hydraulic lines into the cylinder’s chamber either extending or retracting the cylinder rod.The fluid going out from the other chamber of the cylinder is returned to the helm via the other hydraulic line.There are two basic components in all the hydraulic steering systems: the helm unit and the cylinder, connected bynylon or copper tubing. The helm unit consists of both a hydraulic pump and a valve assembly.The valve assembly prevents outgoing fluid from returning along the same line, isolates each steering station, locks therudder and eliminates rudder “feedback” to the helm.The cylinders are double acting and may be balanced or unbalanced (in which case the rod extends through only oneend of the cylinder).SELECTION OF A HYDRAULIC STEERING SYSTEMThe strength required to drive a boat equipped with a hydraulic steering system is inversely proportional to the number of turns ofthe wheel lock-to-lock. The wheel turns are determined by the ratio between the cylinder volume and pump displacement.With the same type of cylinder installed on the engine, the less are the turns, the faster is the response but higher is the effort; morewheel turns, slower is the response and lower is the effort.Other factors that can influence steering effort are:■ Vessel speed■ Rudder dimension, or engine power■ Hull type (displacement, planing, etc.)HYDRAULIC STEERING SYSTEMS - CROSS REFERENCECylinder modelUC94-OBFUC68-OBSUC128-OBFUC128-SVSUC132-OBSUC94-OBFUC128-OBFUC128-SVSUC68-OBSUC132-OBSUC133-IOBUC69-IUC116-IUC168-IUC215-IUC293-IUC378-IUC128-OBFUC128-SVSUC132-OBSUC133-IOBUC116-IUC168-IUC215-ISingle enginesingle cylinderUP2020cc4,7--3,4/5,0--3,5-----UP2828cc----8,2--OUTBOARD CYLINDERS Maximum power rating applicableDouble engine single cylinder Double engine double cylinderPower max hp150150300350300UP2525cc-4,8--5,3/6,55,6-4,66,78,6--UP3333cc7,3-8,0/9,88,07,0--NON counterrotating propellersPower max hpnot applicablenot applicable300350300STEERING WHEEL TURNS single cylinderUP2828cc-4,3--4,7/5,84,7-4,16,07,7--UP3939cc6,2-6,8/8,46,86,08,6-UP3333cc-3,6--4,0/4,94,0-3,55,16,58,9-UP4545cc5,3-5,8/7,25,85,27,49,5counterrotating propellersUP 3939cc-3,1--3,4/4,23,4-3,04,35,57,59,7STEERING WHEEL TURNS double cylinderPower max hp Power max hp Power max hpnot applicablenot applicable500600450not applicablenot applicable500600500not applicablenot applicable600700600UP33-SVS33cc-7,3-----NON counterrotating propellersUP4545 cc----2,9/3,62,9--3,7-6,58,4UP39-SVS39cc-6,2-----UP28-SVS28cc--4,3---------counterrotating propellersUP33-SVS33cc--3,6---------UP39-SVS39cc--3,1---------SuggestedWARNING: These recommendationsshould be used as a general referenceonly.
