Stainless Jet Pump Wear Ring for Sea-Doo GSI 720 1997

Stainless Jet Pump Wear Ring for Sea-Doo

This stainless steel jet pump wear ring is a replacement component designed for the Sea-Doo GSI 720, restoring the tight clearance between the impeller and pump housing that keeps water pressure strong and propulsion efficient.

Overview

This jet pump wear ring serves as the sacrificial surface inside the pump housing on the Sea-Doo GSI 720, protecting the housing while maintaining the close tolerance the impeller needs to move water effectively. Riders and mechanics replacing a worn or scored ring will find it a straightforward swap that helps bring pump performance back toward factory spec.

Built For Performance

• Stainless steel construction resists corrosion in fresh and salt water
• Machined to hold the impeller-to-housing clearance that supports strong thrust
• Withstands the abrasion of sand and debris pulled through the pump
• Direct replacement for the factory wear ring position
• Helps reduce cavitation and restore acceleration response

Fits These Machines

• for Sea-Doo GSI 720 (1997)

On-The-Job Use

• Routine pump rebuilds on the GSI 720
• Restoring performance after impeller damage or debris ingestion
• Freshwater and saltwater riding where corrosion protection matters
• Preventive maintenance before cavitation becomes noticeable

Specs At A Glance

Good To Know

Q: How do I know the wear ring needs replacing? A: A worn ring usually shows up as cavitation, slower hole shots, or a visible gap between the impeller and housing when the pump is opened. Measuring the clearance against spec confirms whether replacement is due.

Q: Does the pump have to come apart to install it? A: Yes, the pump assembly must be removed and the housing separated so the old ring can be taken out and the new one seated. Many riders pair the job with an impeller inspection while everything is accessible.

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