Trim Tab
WARNING
Improper trim tab adjustment can cause dif-
ficult steering.

The trim tab is also an anti-corrosion anode.
Disintegration of the anode can effect boat
handling and performance. Make sure the
trim tab is in good condition and adjust
properly.
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 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:
4)
Pour the recommended oil into the oil fill until
it reaches the upper mark on the dipstick. Re-
fer to Engine Specifications for crankcase
capacity.
Replace the oil fill cap and clean any spilled
oil off the engine and your skin.

7)
Reinstall the upper cover.
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.
Supply water to the cooling system and run
the engine at idle to check for leaks, especial-
ly around drain screw and oil fill cap. Correct
any problems.
8)
Stop the engine and recheck crankcase oil
level using the dipstick. Add oil as indicated.

Test the boat and, if needed, repeat the procedure
until steering effort is as equal as possible.
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.
Dispose of used oil in a reasonable manner follow-
ing all local regulations.
Dual standard rotation motors — Move both of
the trim tabs equally and in the same direction.
Dual motors (one counter and one standard ro-
tation) — Set both trim tabs to the center position.
