Jet Pump Wear Ring 155.3mm ID for Sea-Doo 3D RFI 800 2005

Jet Pump Wear Ring for Sea-Doo 3D RFI 800

This jet pump wear ring for Sea-Doo 3D RFI 800 is a 155.3mm ID replacement component that maintains proper clearance between the impeller and pump housing for consistent thrust and reduced cavitation.

Overview

This jet pump wear ring for Sea-Doo 3D RFI 800 restores the critical clearance between impeller and housing that degrades over time from sand, debris, and normal wear. A fresh jet pump wear ring for Sea-Doo helps recover lost acceleration and top speed caused by excessive impeller-to-ring clearance. It is built for riders performing routine pump maintenance on their 2005 Sea-Doo 3D RFI 800.

Built For Performance

• 155.3mm inner diameter sized for the 3D RFI 800 jet pump housing
• Maintains correct impeller clearance to reduce cavitation and slip
• Durable construction resists abrasion from sand and grit
• Direct replacement for the worn ring in the pump assembly
• Restores holeshot and top-end thrust lost to wear

Fits These Machines

• for Sea-Doo 3D RFI 800 (2005)

On-The-Job Use

• Routine jet pump rebuilds and impeller replacement jobs
• Restoring performance after riding in shallow or sandy water
• Seasonal maintenance before putting the craft back on the water
• Correcting cavitation, slipping, or sluggish acceleration

Specs At A Glance

Good To Know

Q: How do I know the wear ring needs replacing? A: Common signs include cavitation, slipping under acceleration, and a visible gap or grooves between the impeller and ring. Measuring the inner diameter against spec confirms whether replacement is needed.

Q: Does the wear ring come with the impeller? A: This listing is for the wear ring only; the impeller and other pump components are not included. Confirm your pump model and ring size 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.
