Abstract
Systems are for cooling a marine engine that is operated in a body of water. The systems can include an open loop cooling circuit for cooling the marine engine, wherein the open loop cooling circuit is configured to convey cooling water from the body of water to the marine engine so that heat is exchanged between the cooling water and the marine engine, and a pump that is configured to pump the cooling water from upstream to downstream through the open loop cooling circuit. A heat exchanger is configured to cause an exchange of heat between the cooling water located upstream of the marine engine and the cooling water located downstream of the marine engine to thereby warm the cooling water located upstream of the marine engine, prior to cooling the marine engine.
