Boat Hardware Engine Cooling System Diagram The jet boat cooling system. the jet boat cooling system is a vital part of keeping the engine of a jet boat running efficiently. it consists of three main components: an intake, a pump, and a heat exchanger. the intake takes in water from the lake or river and passes it through the pump. the pump helps to move the water throughout the system. The cooling system diagram of a yamaha jet boat typically consists of several key components, including the raw water intake, the impeller, the exhaust system, and the heat exchanger. the raw water intake is responsible for drawing water from the surrounding environment, while the impeller helps circulate the water through the engine and other.
2 3 Jet Boat Project Page 2 The Ranger Station The average jet drive can build pressures in excess of 150psi and the engine cooling system is designed for no more than a maximum of 22 25psi. excessive water jacket pressures can cause head gasket and intake manifold gasket problems and water in the oil. once again, oldsmobiles are especially vulnerable to this problem. In this video jetboatpilot demonstrates the difference in cooling water stream intensity when at idle, at higher rpm and when flushing the cooling system on. In your diagram, cooling water comes in from 1 if the boat is in the water. out of the water, you need to connect a water hose to an adapter which connects to 3 (note: be sure to turn on the engine first before flowing hose water into 3 or you can risk damage to engine by flooding it) see video by yamaha of panama for proper flushing procedure. Location: miami, fl. year: 2010. make: yamaha. model: 212ss. i guess this is me with nothing better to do. but it bothered me i couldn't really figure out how the cooling system works in my boat from looking at the service manual (did i mention that yamaha's service documentation sucks). so here is a drawing i made based on info from the manual.
