Sea-Doo 140mm Jet Pump Repair Kit (1994-2002) | WSM 003-641
The WSM 003-641 Sea-Doo 140mm Jet Pump Repair Kit is a complete rebuild solution for Sea-Doo personal watercraft equipped with the 140mm pump system from 1994-2002. This high-quality aftermarket kit includes the essential bearings and seals needed to restore smooth, reliable jet pump operation and help maintain peak performance.

Worn pump components can lead to cavitation, vibration, water leaks, bearing noise, reduced acceleration, and loss of overall performance. Replacing these critical wear items helps restore pump efficiency, improve reliability, and extend the life of your watercraft.
