ABSTRACT:
Several embodiments of marine propulsion exhaust systems including water lock devices for precluding the entry of water into the engine through its exhaust ports. In each embodiment, the water lock device comprises a control valve that has flow openings for permitting the flow of exhaust gases through the control valve even when the control valve is in its closed position. The flow openings are, however, positioned so as to prevent the flow of water into the engine under these conditions. The openings also create different effective areas so that exhaust pressure tends to open the valve and water pressure tends to close the valve.
