Boat Engine Basics ~ Cooling

Last, but certainly not least, the cooling system of a boat engine is necessary for proper operation. However, where most other parts or functions of a boat engine are similar to that of an automobile engine, the cooling system is actually quite different. For a boat engine, raw water is pumped directly from the ocean, river or lake in which the boat is currently resting.

This water is then channeled through the engine block’s water jacket and is then circulated by the water pump where the water then flows into the risers. These specialty devices mix the boat exhaust with the water and the exhaust then forces the hot water back into the lake. And there you have it, in five days we have covered the basic parts of any boat engine so that, hopefully, you know a little more about its inner workings.
