271001236 Jet Pump Wear Ring 155.5mm for Sea-Doo GTI SE 170 1630 2020-2026

Jet Pump Wear Ring for Sea-Doo

This jet pump wear ring for Sea-Doo is a replacement wear ring with a 155.5 mm inner diameter, built to restore the correct impeller clearance inside the pump housing so your jet drive pushes water with full efficiency; it cross-references OEM part number 271001236.

Overview

The jet pump wear ring for Sea-Doo is a wear component that lines the pump housing and controls the gap between the impeller and housing wall. A worn ring lets water slip past the impeller, costing acceleration and top speed, so fitting this wear ring brings pump performance back to spec. It suits riders and technicians servicing Sea-Doo GTI SE 170 1630 models who want reliable jet pump operation.

Good To Know

Q: What tells me the wear ring is due for replacement? A: Symptoms include slower top speed, weaker acceleration, and a cavitation or slipping sensation under throttle. Checking impeller-to-ring clearance against the service spec confirms when replacement is needed.

Q: Will this ring fit other Sea-Doo models? A: Fitment depends on the pump housing and impeller in use, so verify the 155.5 mm bore and OEM part number 271001236 match your machine. Comparing your model and serial number against the listing helps avoid a wrong fit.

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