Yamaha 144mm Jet Pump Housing (6R7) | WSM 003-507
The WSM 003-507 Yamaha 144mm Jet Pump Housing is a high-quality aftermarket replacement designed to restore pump performance and reliability for Yamaha personal watercraft equipped with the 6R7 pump system. Manufactured from durable marine-grade aluminum, this housing is a direct replacement for the OEM Yamaha pump housing and includes a replaceable plastic wear ring for easier maintenance and lower long-term ownership costs.
Unlike the factory housing that utilizes a thin stainless-steel liner, the WSM design incorporates a replaceable plastic wear ring that can be quickly and inexpensively replaced when damaged by debris, cavitation, or bearing failure. This allows riders to restore proper impeller clearance without replacing the entire housing assembly.
Maintaining tight tolerances between the impeller and wear ring is critical for maximizing acceleration, reducing cavitation, improving hook-up, and maintaining top speed. The WSM 144mm housing is engineered to meet OEM specifications while providing a practical serviceable design for recreational and performance applications.

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.
