ABSTRACT:
A cooling system for a marine propulsion device incorporates both a closed portion and an open portion. The closed portion is operated to encourage nucleate boiling and is provided with a pump and a valve in order to regulate the rate of flow of coolant through certain heat emitting regions of the engine. The pump can be an electric variable speed pump and the valve can be used to direct coolant through a heat exchanger or to bypass the coolant around the heat exchanger.
