Abstract

A closed coolant circulating system for a watercraft, for traveling along a surface of a body of water, containing a supply of coolant that is caused to flow through the coolant circulating system. The watercraft comprises a hull and an engine. The watercraft also comprises a heat exchanger formed from heat conductive material and having a fluid path defined therein with an inlet port and an outlet port. The heat exchanger has a heat exchanging exterior surface and is mounted to the hull such that the heat exchanging exterior surface constitutes a portion of the exterior surface of the hull that is normally disposed below the surface of the body of water. The heat conductive material of the heat exchanger allows the heat absorbed by the coolant to dissipate from the coolant to the body of water via the heat exchanging exterior surface as the coolant flows through the fluid path.
