How is a jet ski propelled through the water?

Jet ski engines pull in water, and push it out the back end. The water being pulled in moves the jet ski forward just slightly, but it’s the power built into the engine as it pushes it out that moves you forward. As the water caught in the engine collides with the water of your surroundings, you begin to move.

Why do jet skis shoot water out the back?

The motor works hard to suck water into the vent at the bottom of the machine, and propel it from the back. Some of that water is used to cool down the motor so the watercraft does not overheat. Once the water has completed its cooling duties, it is expelled out the back of the vehicle in a neat water plume.

Do jet skis have jet engines?

Your jet ski has a jet propulsion engine, which has an impeller that uses rotating fan blades to suck water into the engine and then forcefully eject it. These two motions—sucking in water and then ejecting it back out—are what propel the jet ski forward. Jet skis have throttles, similar to those on motorcycles.
