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 compensate for this steering torque in many cases and can be adjusted
within limits to reduce any unequal steering effort.
26816
NOTE: Trim tab adjustment will have little effect reducing steering torque if the
outboard is installed with the anti‑ventilation plate approximately 50 mm
(2 inches) or more above the boat bottom.
Operate your boat at normal cruising speed, trimmed to the desired position.
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. Tighten bolt and retest.
