Sea-Doo 4-Tec Jet Pump Repair Kit (2004-2015) – WSM 003-645
Restore the performance and reliability of your Sea-Doo 4-Tec jet pump with the WSM 003-645 Pump Repair Kit. Designed specifically for 2004-2015 Sea-Doo 4-Tec personal watercraft, this complete rebuild kit includes all the essential bearings, oil seals, and O-rings needed to rebuild your jet pump and return it to like-new operating condition.
Over time, jet pump bearings and seals can wear due to water intrusion, corrosion, heat, sand, and debris. Worn components often cause cavitation, vibration, water leaks, excessive pump noise, reduced acceleration, and overall performance loss. Replacing these critical wear items helps restore smooth pump operation, improve efficiency, and extend the life of your watercraft.
The WSM 003-645 kit provides all the necessary internal service components in one convenient package, eliminating the need to source individual bearings and seals separately. Ideal for preventative maintenance, pump rebuilds, repairs, and performance restorations.
Manufactured from premium marine-grade materials, this kit is designed to withstand the demanding conditions of both freshwater and saltwater environments.

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.
