271001236 Jet Pump Wear Ring 155.5 mm for Sea-Doo Wake STD 155 1503 2017-2019

Jet Pump Wear Ring (155.5 mm ID) 271001236 for Sea-Doo

This jet pump wear ring with a 155.5 mm inner diameter, OEM cross-reference 271001236, restores the tight clearance between the impeller and pump housing for consistent thrust and reduced cavitation.

Overview

This jet pump wear ring is a direct-fit replacement for the worn ring in your Sea-Doo jet pump assembly, sized at 155.5 mm ID to match the factory specification. By re-establishing the critical clearance between impeller and housing bore, this wear ring helps recover lost acceleration and keeps the pump flowing cleanly at every throttle position. It is intended for riders and mechanics servicing Sea-Doo watercraft with the 1503 engine who want OEM-style fitment without the original brand price.

Specs At A Glance

Good To Know

Q: How do I know if my wear ring needs replacing? A: Cavitation, vibration, or a drop in top speed and acceleration often point to excessive clearance between the impeller and the wear ring. Inspecting the ring for scoring or grooves when the pump is apart confirms whether replacement is needed.

Q: Does the new ring need to be sealed or pressed in? A: Wear rings are typically pressed into the pump housing and may require sealant or a retaining method per the service procedure. Have the pump housing bore and impeller checked for wear at the same time.

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