I am a novice at boating and I am having trouble with water spray traveling up my motor shaft and back into the transom. Is it possible to move the motor up on the transom so that the L-shape motor bracket no longer attaches to the transom. All that will be holding the motor to the transom is the 4 mounting bolts.<br /><br />The motor is a 40 hp Mariner 4cyl and is mounted on a 1648 Alweld aluminum tunnel hull boat with all-metal transom. Right now the cavitation plate is located half way between the bottom of the hull and the top of the tunnel.<br /><br />I have considered a manual jackplate, but if I can safely run the motor mounted higher on the transom without one, I would like to go that route.
