Jet Pump Wear Ring 155mm for Yamaha Wave Raider 1100 1995-1996

Jet Pump Wear Ring for Yamaha Wave Raider 1100

This 155mm jet pump wear ring is a replacement component that restores the tight clearance between the impeller and pump housing on Yamaha Wave Raider 1100 personal watercraft, helping maintain proper thrust and reduce cavitation.

Overview

This jet pump wear ring is a direct-fit replacement for the worn ring in the 155mm pump used on Yamaha Wave Raider 1100 models from 1995 to 1996. The ring sits inside the pump housing and keeps the gap between the impeller tips and the housing wall within spec so the pump can move water efficiently. It is intended for riders and mechanics rebuilding a pump or chasing lost top-end speed caused by a worn wear ring.

Specs At A Glance

Good To Know

Q: How do I know my wear ring needs replacing? A: Common signs include cavitation on holeshot, a drop in top speed, and visible scoring or an enlarged gap between the impeller tips and the ring. Measuring the clearance against spec confirms it.

Q: Can I install this ring without removing the pump? A: No, the pump typically has to come out so the old ring can be pressed or driven out and the new one seated properly. Follow your service manual for the correct procedure.

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