Jet Pump Wear Ring for Sea-Doo

This jet pump wear ring is a replacement component sized at 155.3mm inside diameter that restores proper clearance between the impeller and pump housing for Sea-Doo personal watercraft.

Overview

This jet pump wear ring serves as a direct replacement for worn or damaged rings in Sea-Doo GSX LTD 951 models from 1998 through 1999. The jet pump wear ring maintains the critical clearance between the impeller and the pump housing wall, preserving thrust and reducing cavitation. It is intended for riders and mechanics performing routine pump maintenance on 951-powered Sea-Doo watercraft.

Specs At A Glance

Good To Know

Q: How do I know my wear ring needs replacing? A: Common signs include cavitation, sluggish acceleration, and visible scoring or deep grooves on the ring surface when the pump is removed. Inspecting the ring during impeller service is the best time to catch wear.

Q: Does this ring fit other Sea-Doo models? A: This ring is sized for the 951 GSX LTD platform listed above. Since pump housings vary across models and years, confirm your pump part number and measured diameter 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.
