PLACING TILT PIN IN LOWER HOLES CAN:
1. Lower the bow.
2. Result in quicker planing off, especially with a
heavy load or a stern heavy boat.
3. Generally improve the ride in choppy water.
4. Increase steering torque or pull to the right (with
the normal right hand rotation propeller).
5. In excess, lower the bow of some boats to a point
where they begin to plow with their bow in the wa-
ter while on plane. This can result in an unex-
pected turn in either direction called “bow steer-
ing” or “over steering” if any turn is attempted or
if a significant wave is encountered.
PLACING TILT PIN IN UPPER HOLES CAN:
1. Lift the bow out of the water.
2. Generally increase top speed.
3. Increase clearance over submerged objects or a
shallow bottom.
4. Increase steering torque or pull to the left at a nor-
mal installation height (with the normal right hand
rotation propeller).
5. In excess, cause boat “porpoising” (bouncing) or
propeller ventilation.
Trim Tab Adjustment
Propeller steering torque will cause your boat to pull
in one direction. This steering torque is a normal thing
that results from your outboard not being trimmed so
the propeller shaft is parallel to the water surface. The
trim tab can help to compensate for this steering
torque in many cases and can be adjusted within lim-
its to reduce any unequal steering effort.
NOTE: Trim tab adjustment will have little effect re-
ducing steering torque if the outboard is installed with
the anti-ventilation plate approximately 2 inches
(50mm) or more above the boat bottom.
MODELS WITHOUT POWER TRIM
Operate your boat at normal cruising speed trimmed
to desired position by installing the “tilt pin” in the de-
sired tilt pin hole. Turn your boat left and right and note
the direction the boat turns more easily.
If adjustment is necessary, loosen trim tab bolt and
make small adjustments at a time. If the boat turns
more easily to the left, move the trailing edge of trim
tab to the left. If the boat turns more easily to the right
move the trailing edge of trim tab to the right. Retigh-
ten bolt and retest.
MODELS WITH POWER TRIM
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.

more easily to the left, move the trailing edge of trim
tab to the left. If the boat turns more easily to the right
