ABSTRACT:
An integrated splash and anti-cavitation plate is provided for an outboard motor. The integrated plate decreases the overall weight of the outboard motor in order to improve the motor's performance. The decreased weight also lessens the load on the mounting structure which supports the outboard motor on the watercraft transom. In addition, the distance between the plate and the rotational axis of the propulsion shaft is such that the plate can effectively prevent water splash-up into the mounting structure, even when the outboard motor is run with its propellers partially exposed.
