R
If your boat is equipped with a hydraulic steering
system. The steering consists of:
• Steering wheel and helm pump unit
• Engine hydraulic cylinder
• Hydraulic hoses and fittings
Operation
When turning the steering wheel either clockwise or
counterclockwise, the helm pump forces hydraulic
fluid through hoses to and from the engine cylinder
which is connected to the tiller arm. The engine
cylinder moves the tiller arm to port and starboard,
depending upon the direction the steering wheel is
turned.

Propeller steering torque will cause your boat
to pull in one direction. This steering torque is a
normal result of your outboard not trimmed with the
propeller shaft parallel to the water surface. The trim
tab can utilized to compensate for this steering torque
in many cases and can be adjusted within limits to
reduce any unequal steering effort.
Trim Tab Adjustment
Operate your boat at normal cruising speed, trimmed
to desired position. Turn your boat left and right and
note the direction the boat turns more easily.
