ABSTRACT:
A valve apparatus for a marine vessel has a housing with first, second, and third ports and a valve member within the housing. The housing is mounted to the hull of the vessel with the first port communicating with the body of water outside of the vessel. The third port is connected to the cooling system of an engine in the vessel and the second port is closed by a quick-release plug. The valve member is movable to open and close communication with the outside. During normal operation, water is drawn through the structure into the engine cooling system and is discharged overboard. In an emergency, the plug can be removed and the valve member moved to a 90.degree. position in which communication with the outside is closed, allowing the engine to draw water from within the hull and discharge it overboard. The structure can also be used with a service adapter for engine flushing and other maintenance.
