INSTALLATION AND PREDELIVERY
FINAL ADJUSTMENTS
Trim Tab Adjustment
A propeller will generate steering torque when the
propeller shaft is not running parallel to the water’s
surface. The trim tab is adjustable to compensate
for this steering torque.
IMPORTANT:
A single trim tab adjustment will
relieve steering effort under only one set of speed,
outboard angle and load conditions. No single
adjustment can relieve steering effort under all
conditions.
If the boat pulls to the left or right when its load is
evenly distributed, adjust the trim tab as follows:
•
With the engine OFF, loosen the trim tab screw.
If the boat pulled to the right, move rear of the
trim tab slightly to the right. If the boat pulled to
the left, move rear of the trim tab slightly to the
left.
•
Tighten the trim tab screw to a torque of 35 to
40 ft. lbs. (47 to 54 N·m).
Test the boat and, if needed, repeat the procedure
until steering effort is as equal as possible.
Outboards with High Transom Heights
The trim tab may be above the surface of the
water when the outboard is trimmed out. Steering
effort might increase. Lower the trim setting to
submerge the trim tab and to reduce steering
effort.
Dual Standard Rotation Outboards
Move both trim tabs equally and in the same
direction.
Dual Outboards, One Counter and One
Standard Rotation
Set both trim tabs to the center position.
WARNING
Improper trim tab adjustment can cause
difficult steering and loss of control.
