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 limits to reduce any unequal steering effort.
NOTE: Trim tab adjustment will have little effect reducing steering torque if the outboard is
installed with the anti-ventilation plate approximately 2 inches (50mm) or more above the
boat bottom.
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.
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. Retighten bolt and retest.
