Impeller
Damage to the leading edges of the impeller blades causes flow separation and the formation of vapor bubbles (cavitation). This physical degradation results in a loss of propulsion and mechanical vibration as the impeller becomes unbalanced. Replacing the impeller restores the intended hydrodynamics of the jet pump system.

Jet Pump Housing (Wear Ring)
The clearance between the impeller and the wear ring must be extremely tight to maintain pressure. If debris has been ingested, the inner lining of the housing is often scored or gouged, allowing water to 'slip' around the blades rather than being forced through the nozzle. A new housing restores this critical seal, eliminating cavitation during acceleration.

Pump Shoe Seal Kit
Air leaks at the intake grate or pump shoe interface can introduce air into the water stream, simulating the symptoms of cavitation (spinning but no 'grip'). Using a sealant or plug kit ensures a vacuum-tight transition from the hull intake to the pump, preventing air ingestion that causes vibration and RPM surges.
