Power Trim & Tilt
ATTENTION
Ensure continuous visibility of other boats,
swimmers and obstacles during bow-up
transition to planing. Adjust engine to an
intermediate trim as soon as boat is on plane.
The power trim & tilt system located on the shift
control lever (Fig. 2.10.1).allows you to raise and
lower the engine to achieve optimum performance.
It is also used for launching and beaching.

Operation

The engine trim is controlled by a momentary rocker
switch, where constant pressure must be applied to
the switch during the raising and lowering cycles.
Use the power trim switch to obtain ideal boat angle
(in relation to the water surface) for a given load and
water condition. In most cases the best all-round
performance is obtained when the boat runs at an
angle between a 3 to 5 degrees.

Hydraulic Steering

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.

Steering Torque

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 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.
If adjustment is necessary,
• Loosen the bolt on the underside center of
the tab.
NOTE: Make small adjustments at a time.
• If boat turns more easily to the right, move
the trailing edge of the trim tab to the right.
• If boat turns more easily to the left, move
the trailing edge of the trim tab to the left.
• Tighten bolt and retest.
