Jet Pump Wear Ring 155.3mm ID for Sea-Doo GTI RFI 800 2004-2005

Jet Pump Wear Ring for Sea-Doo GTI RFI 800

This jet pump wear ring for Sea-Doo GTI RFI 800 watercraft restores the close clearance between the impeller and pump housing, protecting thrust and reducing cavitation.

Overview

This jet pump wear ring for Sea-Doo is a direct-fit replacement for the worn ring in the 155.3mm ID pump used on GTI RFI 800 models. It keeps the impeller-to-housing gap within spec so acceleration stays crisp and the pump stops losing grip. It suits riders maintaining a 2004 to 2005 Sea-Doo GTI RFI 800 or anyone rebuilding a pump on the bench.

Built For Performance

• Precision 155.3mm inner diameter matches the factory pump bore for consistent impeller clearance
• Wear-resistant construction stands up to abrasive water, sand, and debris pulled through the pump
• Direct replacement for the original ring, no machining or modification required
• Restores lost thrust and reduces cavitation caused by an eroded ring surface
• Simple press-fit installation during routine pump service

Fits These Machines

• for Sea-Doo GTI RFI 800, 2004-2005

On-The-Job Use

• Routine jet pump rebuilds on 2004 to 2005 GTI RFI 800 watercraft
• Restoring acceleration after cavitation or slipping is noticed on holeshot
• Freshwater and light saltwater riding where pump wear is a normal service item
• Shop and DIY pump service where a correct-diameter ring is needed fast

Specs At A Glance

Good To Know

Q: How do I know the wear ring needs replacing? A: Cavitation, a rough holeshot, or a visible groove or erosion in the ring surface are the usual signs on a jet pump. Measuring the inner diameter against 155.3mm confirms it.

Q: Does the impeller need to come out to install this ring? A: Yes, the pump is disassembled and the impeller removed so the new wear ring can be seated in the housing. It is a standard part of a pump rebuild.

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