Yamaha 155mm Jet Pump Housing (63M) | WSM 003-505
The WSM 003-505 Yamaha 155mm Jet Pump Housing is a premium aftermarket replacement designed for Yamaha personal watercraft equipped with the 63M pump system. Manufactured from durable marine-grade aluminum, this housing is a direct replacement for the OEM Yamaha pump housing while offering the added advantage of 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 features a serviceable plastic wear ring that can be easily replaced when worn or damaged. This allows you to restore proper impeller clearance and pump performance without replacing the entire housing assembly.
Over time, wear rings can become damaged from rocks, sand, debris, cavitation, or failing pump bearings. Excessive clearance between the impeller and wear ring reduces pump efficiency and can lead to cavitation, poor acceleration, reduced hook-up, and loss of top speed. Simply replace the liner and restore your pump to peak performance.
Designed to meet or exceed OEM specifications, the WSM 155mm housing is ideal for stock replacements, pump rebuilds, and performance applications.
Features
Direct replacement Yamaha 155mm jet pump housing manufactured from high-strength marine-grade aluminum. Includes a replaceable plastic wear ring for easy servicing and lower maintenance costs. Designed to restore proper impeller clearance, improve pump efficiency, and maximize overall watercraft performance.
Benefits
Helps eliminate cavitation, restore acceleration, improve hook-up, and maintain top speed. Replaceable wear ring design allows future repairs without replacing the complete housing. Durable aluminum construction provides excellent strength, corrosion resistance, and long service life.

Why Choose a Replaceable Wear Ring Housing?
When a wear ring becomes damaged from rocks, debris, cavitation, or worn bearings, the WSM replaceable liner system allows you to install a new wear ring instead of replacing the entire housing. This significantly reduces maintenance costs while helping maintain maximum pump efficiency and performance.

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.
