Yamaha 144mm Replacement Pump Liner (6R8) | WSM 003-521-1
The WSM 003-521-1 Yamaha 144mm Replacement Pump Liner is a direct replacement wear ring liner designed for WSM aluminum jet pump housings utilizing the Yamaha 6R8 pump system. This replaceable liner restores proper impeller clearance and pump efficiency without the expense of replacing the entire pump housing.
Over time, the pump liner can become worn or damaged from rocks, sand, debris, cavitation, or failing pump bearings. As the gap between the impeller and liner increases, pump performance suffers, resulting in cavitation, reduced acceleration, poor hook-up, and loss of top speed.
The serviceable WSM design allows you to simply remove the damaged liner and install a new replacement, restoring factory-like clearances and maximizing pump performance. This cost-effective solution helps extend the life of your aluminum pump housing while maintaining optimal jet pump efficiency.
Manufactured from durable, wear-resistant materials, the WSM replacement liner is engineered to withstand harsh marine environments and demanding riding conditions.
Features
Designed specifically for WSM Yamaha 144mm aluminum pump housings using the 6R8 pump system. Restores proper impeller-to-liner clearance, improves pump efficiency, and eliminates the need to replace the complete housing. Durable construction provides excellent wear resistance and long service life.
Benefits
Helps reduce cavitation, restore acceleration, improve hook-up, and maximize pump performance. Cost-effective maintenance solution that extends the life of your jet pump housing.

FAQs

How do I change the impeller in my craft?
Impros has complete impeller installation instructions for Yamaha, Sea-Doo, Kawasaki and Polaris PWC. See Impeller Installation instructions for the person that likes to get in there and do things themselves.
Does Impros balance each impeller they service?
Yes. Each and every impeller that we service is checked for accurate balance within 2/10ths of a gram. Slight rock damage and especially with impellers requiring weld, checking the balance is absolutely required with PWC impellers. Sometimes we’ll find new impellers out of balance right out of the box. We balance each impeller as the finish is applied, eliminating any chance of throwing it out of balance during the polishing process. These measures are proudly taken to insure our customers the highest quality impeller repair available. Ask our competition if and how they balance impellers, we’ve found that they typically rely on the original factory balance.
Does Impros use correct pitching techniques specific to each brand of impeller?
Yes, Impros is proud of our ability to pitch each brand impeller to the manufacture’s specific range of blade angle variation. Impros has a master gauge for every stainless-steel impeller made, assuring an accurate pitch and uncompromised performance, eliminating common guesswork. Each and every manufacturer builds the impeller geometrically different from one another and gauges the outer blade angle in a different way. Only a company with experience will accurately understand, manipulate and repair the blades of the impeller to its original state.
