Steering Friction
IMPORTANT: A single trim tab adjustment will re-
lieve steering effort under only one set of speed,
motor angle and load conditions. No single adjust-
ment can relieve steering effort under all speed,
motor angle and load conditions. If the boat pulls to
the left or right when its load is evenly distributed,
adjust the trim tab as follows:
With the motor shut OFF, loosen the trim tab
screw. If the boat pulled to the right, move the rear
of the trim tab slightly to the right. If the boat pulled
to the left, move the rear of the trim tab slightly to
the left.
The steering friction was set on your new motor be-
fore it left the factory. After the first 10 hours of ser-
vice, check to see that it is still correct. A slight drag
should be felt when turning the motor. If adjustment
is necessary, turn the adjustment screw:
•
•
Clockwise to increase friction; or
Counterclockwise to decrease friction.

WARNING
Tighten the trim tab screw to a torque of 18 to 20 ft.
lbs. (24 to 27 N·m).
DO NOT overtighten for “hands-off” steer-
ing. Reduced steering control could result.
Test the boat and, if needed, repeat the procedure
until steering effort is as equal as possible.
Trim Tab
High motor installations — The trim tab might
be above the water when the motor is trimmed out.
Steering effort might increase. Steering effort will
be reduced if you trim the motor in and submerge
the trim tab.
WARNING
Improper trim tab adjustment can cause dif-
ficult steering.
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.
