Installation Guide MPE 750 Turbo Marine Closed Loop Flush System Especially for the use of the boat in salt water a fl ush system to rinse the open loop cooling circuit is recommended. Therefore a fl ush system has to be implemented by the boat builder.
Installation Guide MPE 750 Turbo Marine Closed Loop Boat tow In combination with a jet propulsion system there is a risk to fi ll the engine with water by towing the boat. The engine has a wet exhaust system. This means sea water is injected into the exhaust out of the open loop cooling circuit.
Installation Guide MPE 750 Turbo Marine Closed Loop Exhaust System The exhaust system of the spark ignition marine engine is water cooled. A part of the sea water is injected into the manifold to reduce the exhaust temperature and the noise in the system. This injected water will leave the boat through the exhaust system (1).
