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.

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. Retighten
bolt and retest.
