Stainless Jet Pump Wear Ring for Sea-Doo GT 580 1990-1991

Stainless Jet Pump Wear Ring for Sea-Doo

This stainless jet pump wear ring is a direct replacement component for the jet pump assembly on 1990-1991 Sea-Doo GT 580 watercraft, maintaining the critical clearance between the impeller and pump housing.

Overview

This stainless jet pump wear ring is built to restore proper clearance inside the jet pump housing on your Sea-Doo GT 580. A worn wear ring lets water slip past the impeller, robbing you of thrust and top speed, so replacing it with a fresh stainless jet pump wear ring keeps your pump working efficiently. It is designed for riders and mechanics servicing 1990-1991 Sea-Doo GT 580 models.

Built For Performance

• Stainless steel construction for corrosion resistance in fresh and salt water
• Maintains the critical impeller-to-housing clearance for strong jet thrust
• Direct fit replacement for the original wear ring on the Sea-Doo GT 580 jet pump
• Machined dimensions for consistent sealing surface around the impeller
• Resists wear from abrasive debris commonly pulled through jet pumps

Good To Know

Q: How do I know my wear ring needs replacing? A: Common signs include loss of top speed, cavitation, and a rise in engine RPM without matching acceleration. Inspect the ring for deep grooves or scoring that would break the impeller clearance.

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket stainless wear ring made to fit Sea-Doo GT 580 jet pumps. Always confirm your pump model and year 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.
