How does a jet ski stay cool?

Engine Cooling

Modern high-powered engines generate a lot of heat, and jet skis are no different. To handle engine cooling, most jet skis use an open loop cooling system, which takes advantage of cooler external ocean or lake water. … These craft use a heat exchanger.

What is the stream of water behind a jet ski?

What is closed loop cooling?

What is a closed loop cooling system? Closed loop cooling systems are designed to isolate the air within the enclosure from the ambient air. They remove the heat inside the enclosure without letting ambient air inside it. It is the ideal solution to protect sensitive electrical equipment against dust and precipitation.
