What's the difference between an impeller and a propeller?

PWCs use jet propulsion — water is pulled through a jet pump and forced out the back. The impeller is the spinning blade inside the pump. Boats use propellers — exposed blades that spin in open water. PWC propulsion is safer for swimmers and shallower water.

How do I know if my PWC impeller needs replacement?

Reduced top speed, slower acceleration, or 'cavitation' (engine revs without speed gain) all suggest impeller wear. Inspect for bent, chipped, or worn blades. Replace as a set with the wear ring for best results.

How often should I replace the wear ring?

Every 100–200 hours, or whenever you replace the impeller. Worn wear rings reduce power and impeller life. Inspect every 50 hours — looking for grooves, cracks, or oversized clearance.

Pitch up vs. pitch down on my impeller?

Pitch up = more top speed, slower acceleration. Pitch down = quicker acceleration, lower top speed. Match the pitch to your riding style. Tow-heavy users (tubing, wakeboarding) often go pitch down.

Are aftermarket impellers worth it?

Solas, Skat-Trak, and R&D make popular aftermarket impellers with various pitches. They're often less expensive than OEM and offer broader pitch selection. Match the impeller carefully to your engine and riding application.
