Hydraulic steering systems must periodically have all air

The propeller rotation of a single engine installation will    by the hydraulic steering manufacturer for proper specifi-

can cause the steering to be harder in one direction than
the other, and is call propeller torque.
Propeller torque can also cause the boat to wander (not
follow a straight line) when operated at low speeds. This
condition is normal and can be corrected only by increas-
ing engine rpm. Wind, water currents and play in steer-
ing components can cause equivalent effects.
G - 6     STEERINGSYSTEMMAINTENANCE
A periodic inspection of the  helm pump and reservoir,
hydraulic hoses, the hydraulic cylinder, tie bar  assem-
bly,bearing,seals,rudderanglesenderandruddershould
be made.   See Figures G4 -  G6.  Signs of  corrosion,
cracking, loosening of fastenings, excessive wear, or de-
terioration should be immediately corrected.  Failure to
do so could lead  to steering system failure and corre-
sponding loss of control.
The helm should be so adjusted that the steering wheel
is centered with the rudders in the straight ahead posi-
tion.  There should be an equal number of turns to port
and starboard from the straight ahead position. If adjust-
ment becomes necessary, see your Four Winns dealer.
All cables, helm assemblies, and steering connections
should be periodically lubricated with a light, waterproof
grease or as indicated in the manufacturers information
provided in the owner’s packet.

enough to prevent leakage, yet loose enough so exces-

placement of the seal is required.
