271001236 Jet Pump Wear Ring 155.5 mm ID for Sea-Doo Base 19-170 1630 2022-2025

Jet Pump Wear Ring for Sea-Doo

This jet pump wear ring (155.5 mm ID) is a replacement component that maintains proper clearance between the impeller and pump housing to preserve thrust and reduce cavitation, and it cross-references part number 271001236.

Overview

This jet pump wear ring is a direct-fit replacement for Sea-Doo personal watercraft, designed to restore the tight impeller-to-housing clearance that drifting wear erodes over time. A fresh jet pump wear ring helps maintain acceleration, top speed, and pump efficiency so your craft performs the way it should on the water. It is intended for riders and technicians servicing Sea-Doo 1630 ACE-equipped models.

Good To Know

Q: How do I know if my wear ring needs replacing? A: Symptoms include cavitation, lost top speed, and slipping during acceleration, and a visual check of the impeller clearance will confirm wear. Replacing the ring restores pump efficiency.

Q: Does this ring fit other Sea-Doo models? A: It is sized at 155.5 mm ID and cross-references part 271001236, so confirm your model and serial number 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.
