271000290 Jet Pump Wear Ring for Sea-Doo GSI 720 1997

Jet Pump Wear Ring for Sea-Doo

The jet pump wear ring for Sea-Doo 720 models restores proper clearance between the impeller and pump housing, protecting thrust and minimizing cavitation so the pump delivers consistent thrust; it cross-references OEM part 271000290.

Overview

This jet pump wear ring for Sea-Doo is a replacement ring that maintains the critical clearance between impeller and housing, helping preserve pump efficiency and reduce cavitation. It suits riders and mechanics servicing 720-powered personal watercraft who want dependable, direct-fit replacement parts. The wear ring for Sea-Doo pump assemblies is built to withstand the constant water flow and abrasion of jet propulsion.

Specs At A Glance

Good To Know

Q: When should a jet pump wear ring be replaced? A: Replace it when impeller clearance exceeds spec, or when acceleration, thrust, or cavitation issues point to wear. Inspecting the ring during any pump teardown is a sensible habit.

Q: Does a worn wear ring affect top speed? A: Yes, extra clearance lets water slip past the impeller, which reduces thrust and can lower both acceleration and top speed. Restoring proper clearance helps bring pump performance back toward normal.

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