ADJUSTMENTS
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:
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.
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.

Reinstall the upper cover.
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.
