The key to a PWC is a small pump with a rotating part called an impeller. When you crank the throttle, the pump sucks in water through a grate underneath the craft and the impeller blasts it out of a hole at the back, so the force of the jet pushing backward (action) drives the whole craft forward (reaction).
