Jet Pump Wear Ring 155.3mm for Sea-Doo GTX LTD 951 1999

Jet Pump Wear Ring for Sea-Doo GTX LTD 951

This jet pump wear ring is a 155.3mm inner diameter replacement component that restores proper clearance between the impeller and pump housing on 1999 Sea-Doo GTX LTD 951 watercraft.

Overview

This jet pump wear ring serves as the sacrificial surface inside the pump housing, maintaining the tight clearance the impeller needs to move water efficiently. A worn wear ring on a 1999 Sea-Doo GTX LTD 951 allows pressure to slip past the impeller, causing cavitation and sluggish acceleration. Replacing the wear ring with a correctly sized unit brings pump performance back to spec.

• Helps eliminate cavitation and slippage under load

Fits These Machines

• for Sea-Doo GTX LTD 951, 1999

On-The-Job Use

• Pump rebuilds and impeller replacement jobs
• Restoring acceleration after cavitation symptoms appear
• Off-season driveline maintenance on personal watercraft

Good To Know

Q: What causes a wear ring to wear out? A: Sand, gravel, and other debris drawn through the pump grind against the ring surface over time. Once the clearance opens past spec, the impeller no longer moves water efficiently.

Q: Can I replace just the wear ring? A: Yes, this wear ring is designed as a standalone replacement and reuses your existing pump housing. Confirm your pump takes a 155.3mm ring before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
