back of the boat. The cable must be free and clear to
slide back and forth. Any item blocking free movement of
the cable will result in harder steering and possible dam-
age to the steering cable. If unable to locate or correct
the problem, have the steering cable inspected and lubri-
cated by your Four Winns dealer.
After the first two hours of running time, check
the entire steering system for loose bolts, nuts
and fasteners which could adversely affect steer-
ing control.
Check the fluid level in the reservoir periodically.
Low power steering fluid levels may increase
steering difficulty.
NOTICE
DO NOT interfere with or restrict steering cable
movement through the last 90
engine. DO NOT use cable retainers, clamps or
tie straps. Using one or all of these could re-
strict the cable movement near the engine. DO
NOT tie wiring harnesses or other control cables
to the steering cable. Make sure the deck
coaming pads and bulkheads allow for steering
cable movement in all positions of trim.
When storing equipment in the engine compart-
ment, be sure to avoid contact with the steering
cable. Cables may become kinked or damaged
and may increase steering effort.
Additional information on steering operation can be found
in Section Q-9 in this manual and in your Engine Owners
manual.

PROPELLER TORQUE
The propeller rotation of a single engine installation will
exert a directional force on the steering system. This
can cause the steering to be harder in one direction than
the other, and is called propeller torque. If this occurs,
adjust the drive or trim tab (when applicable). Refer to the
Engine Owners manual for information on adjusting the
trim tab.

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.

A periodic inspection of all steering cables, linkage and
helm assemblies should be made. Signs of corrosion,
cracking, loosening of fastenings, excessive wear, or de-
terioration should be immediately corrected. Failure to
m
of bend at the
do so could lead to steering system failure and corre-
sponding loss of control.
The helm and cable assembly should be so adjusted that
the steering wheel is centered with the drive or outboard
engine in the straight ahead position. There should be an
equal number of turns to port and starboard from the
straight ahead position. If adjustment becomes neces-
sary, 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 with this manual.
Steering effort can vary significantly with engine
acceleration, steering angle, trim angle, and sea
condition. Be prepared for additional steering
loads at all times.
