Jet Pump Wear Ring for Yamaha Wave Blaster 700

This 144mm ID jet pump wear ring for Yamaha Wave Blaster 700 sits inside the pump housing to keep the impeller running at a tight, efficient clearance so thrust stays consistent on the water.

Overview

This jet pump wear ring for Yamaha Wave Blaster 700 is a direct-fit replacement for the worn ring that surrounds the impeller in the pump housing. Measured at 144mm inner diameter, it restores the close tolerance between impeller and housing that water flow depends on.

Specs At A Glance

Good To Know

Q: Why does the wear ring need replacing? A: Sand and debris grind the gap between impeller and ring wider over time, and once that clearance opens up the pump loses thrust. A fresh 144mm ring brings the tolerance back to spec.

Q: Should I check the impeller while the pump is apart? A: Yes, inspect the impeller blades for nicks and wear at the same time since the pump has to come apart either way. Replacing both together avoids a second teardown later.

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