A cooling system for an outboard motor pumps water from a body of water through certain selected portions of the outboard motor and through a heat exchanger which, in turn, comprises a coolant conduit that is directed to conduct the coolant in thermal communication with various portions of the outboard motor. The engine block is cooled by a flow of the coolant and an engine head is cooled by a flow of water from the body of water. Other heat emitting devices are connected in thermal and fluid communication with the water and coolant conduits.
