Yamaha 144mm Jet Pump Housing (6R8) | WSM 003-506
The WSM 003-506 Yamaha 144mm Jet Pump Housing is a premium aftermarket replacement designed for Yamaha personal watercraft equipped with the 6R8 pump system. Manufactured from durable marine-grade aluminum, this housing is a direct replacement for the OEM Yamaha pump housing while offering the added benefit of a serviceable replaceable plastic wear ring.
Unlike the factory housing that utilizes a thin stainless-steel liner, the WSM design incorporates a replaceable plastic wear ring that can be easily replaced when worn or damaged. This allows you to restore proper impeller clearance and pump efficiency without the expense of replacing the entire housing assembly.
Over time, wear rings can become damaged from rocks, debris, cavitation, or failing bearings. Excessive clearance between the impeller and wear ring can result in cavitation, poor acceleration, reduced hook-up, and loss of top speed. The WSM replaceable liner system makes maintenance simple and affordable while helping maintain peak jet pump performance.
Designed to meet or exceed OEM specifications, this housing is ideal for stock replacements, pump rebuilds, and performance applications.

Benefits

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.
