2-Stroke PWC & Jet Ski Crankshaft Rebuilding

Your PWC crankshaft takes a beating: high RPM, hard launches, and water that's unforgiving of a worn bottom end. We rebuild 2-stroke personal watercraft and jet ski crankshafts back to spec so your ski runs strong and reliable.

Watercraft & PWC Crankshaft Rebuilding crankshaft rebuild

We rebuild watercraft cranks for Kawasaki, Yamaha, Sea-Doo and Polaris — from the small Kawasaki 440 and 550 up through the Yamaha 1200/1300R and Kawasaki 1200. Many models can also be built with welded webs for added strength, and we offer counterbalance service for the Sea-Doo 785 and 951.

Whether you spun a bearing, ingested water, or you're freshening a high-hour engine, a properly rebuilt, trued and balanced crank is the foundation of a strong-running 2-stroke.
