What is an impeller on a jet ski?
PWC impeller is a rotor and part of a jet pump system that increases the pressure and flow of water to produce the propulsion and thus move the vessel forward.
What is impeller cavitation
Jet ski impellers have small blades which make them able to spin at higher speed.
The faster the blades move, the lower the pressure can become around the blades. It causes formation of small vapor-filled cavities called “bubbles” which collapse and generate shock waves that destroy the edges of the impeller blades. This process is called Cavitation and it can negatively effect your vessel’s performance over time.
Cavitation may be the reason why your jet ski not going as fast as before.
How can you get more power out of your jet ski?
Simple impeller replacement can do the job.
