Abstract
A marine propulsion system with a closed coolant loop is described. The marine propulsion system has a starboard heat exchanger and a port side heat exchanger that provides improved cooling and increases engine life compared with traditional open loop cooling systems, particularly in harsh environments such as salt water, brackish water, swamp, shallow or sediment and debris rich water. The two discrete heat exchangers are mounted to the lower unit of the marine propulsion system and also serve to improve hydrodynamic performance of the marine propulsion system.
