Sea-Doo 4-Tec Jet Pump Repair Kit (2002-2003) | WSM 003-644

The WSM 003-644 Sea-Doo Jet Pump Repair Kit is a complete rebuild solution for 2002-2003 Sea-Doo 4-Tec personal watercraft. This aftermarket kit includes all the bearings, oil seals, and O-rings needed to rebuild your jet pump and restore smooth, reliable performance.

Over time, jet pump bearings and seals wear from water intrusion, corrosion, sand, heat, and normal operation. Worn components can cause cavitation, vibration, water leaks, excessive bearing noise, poor acceleration, and reduced pump efficiency. Replacing these components during routine maintenance helps restore performance and extend the life of your Sea-Doo.

This complete rebuild kit eliminates the hassle of sourcing individual parts and provides everything needed for a professional-quality jet pump rebuild.

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.
