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.
