Yamaha PWC Jet Pump Wear Ring WC-03012
Restore optimal performance to your Yamaha personal watercraft with this precision-moulded jet pump wear ring. This component, also known as an impeller liner, is crucial for maintaining the correct impeller-to-liner clearance. Proper clearance minimizes cavitation, which is the formation of vapor bubbles that can damage the impeller and reduce pump efficiency. This wear ring ensures your jet pump operates at peak performance.
Constructed from durable POM (Delrin) material, this wear ring offers excellent wear resistance and maintains dimensional stability even under demanding conditions. It is designed as a direct-fit replacement, integrating seamlessly with standard OEM-type impellers and specific Yamaha 155 mm jet pump housings in the 63M family. This ensures a straightforward installation process and reliable operation.
