Designed specifically for four-stroke Kawasaki STX-12F and STX-15F runabouts, this WSM replacement impeller shaft is a smart upgrade when refreshing the pump on skis used for towing, touring, or rough-water play. The 1200 and 1500 four-stroke engines deliver strong, linear power that demands a straight, robust shaft to keep the pump running smoothly. A new shaft can help eliminate driveline shudder, improve impeller engagement, and extend the life of surrounding pump components.
- Direct replacement for STX-12F and STX-15F models, including select 1500 STX skis from 2007-2010
- Built to handle continuous high-load use common in tow sports and long-distance riding
- Machined for proper fit with OEM bearings, seals, and Kawasaki impellers
- Great choice during major service, wear ring replacement, or impeller upgrades
- Supports smoother acceleration and a more refined feel at cruising speeds
When installing, verify that the pump bearings spin freely, seals are fresh, and the wear ring clearance is within spec, as these details help protect the new shaft. Use recommended torque procedures on the coupler and impeller to maintain balance and reliability. With this WSM impeller shaft in place, your STX four-stroke can continue to deliver dependable thrust and enjoyable ride quality for seasons to come.
