OPERATION If steering effort is not equal in both directions, adjust the trim tab to compensate for "torque steer," which is the reaction of the outboard motor to propeller rotation
SHALLOW WATER OPERATION
When operating in shallow water, tilt the outboard motor, using the tilt lever, so the propeller and gear case won't hit the bottom
To tilt the outboard motor, move the tilt lever to the TILT position, then raise the outboard motor to the 30" or 45" position by pulling on the engine cover grip
