Trim Tab Adjustment

Propeller steering torque will cause the boat to pull in one direction. This
steering torque is a normal result from the outboard not trimmed with the
propeller shaft 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.
• Operate the boat at normal cruising speed with the outboard set at the
desired operating angle position. Turn the boat left and right and note the
direction the boat turns more easily.
