SERVICING YOUR OUTBOARD MOTOR TRIM TAB ADJUSTMENT RIGHT
The trim tab compensates for “torque steer,” which is a reaction of the outboard motor to propeller rotation. If uncompensated, torque steer would make the outboard motor tend to turn to one side. When the trim tab is correctly adjusted, steering effort is equal in either direction. If steering effort is unequal, remove the gear case grommet and loosen the trim tab bolt then adjust the angle of the trim tab. Retighten the trim tab bolt and reinstall the gear case grommet securely.
