SEA-DOO GTI 130 Wear Ring Cavitation

OEM Pump Wear Ring

The wear ring is a sacrificial composite liner that maintains the hydraulic seal around the impeller blades. Cavitation occurs when the gap between the impeller and this ring exceeds the thickness of a dime, allowing water to bypass the blades and create vacuum pockets. Replacing the worn ring restores the tight tolerances required for efficient thrust and eliminates the 'slipping' sensation under load.

Drive Shaft Carbon Seal Kit

If the wear ring clearance is within specification, the cavitation is likely caused by 'aeration' from a compromised carbon seal. A weakened bellows or a scored carbon ring allows the pump to suck air from the engine compartment into the intake grate. This air breaks the water's surface tension on the impeller blades, causing an immediate loss of hook-up and high-pitched cavitation noise.

Solas Concord Impeller

Nicks, dings, or rolled edges on the stainless steel impeller blades create focal points for cavitation. Even with a new wear ring, a damaged impeller will trigger turbulent flow and cavitation burns at high RPM. A precision-pitched impeller ensures laminar flow and maximizes the pressure differential required for acceleration.
