Abstract

A watercraft includes a sterndrive comprising an inboard engine and an outdrive that extends through the transom. The aft end of the hull includes a stepped tunnel, which allows the sterndrive propellers (or other drives) to be operated at a relatively higher position in the water, without unduly decreasing the propeller performance. The stepped tunnel is vented to atmospheric pressure.
