Crankshaft Assembly for Sea-Doo
This crankshaft assembly is a replacement engine component that transfers piston force into rotational power for Sea-Doo GTS 720 watercraft. It serves riders and mechanics rebuilding a 720 engine who need a fresh crank rather than reusing a worn core.
Overview
This crankshaft assembly is built to restore bottom-end function in Sea-Doo GTS 720 personal watercraft. The crankshaft assembly converts reciprocating piston motion into the rotating force that drives the impeller. It suits riders doing a top-to-bottom engine rebuild and shops servicing older two-stroke Sea-Doo models.
Built For Performance
- Balanced crank throws for smooth rotation at operating RPM
- Precision-machined journals sized for matching bearings
- Sturdy connecting rod construction for repeated load cycles
- Built to original 720 engine dimensions for direct replacement
- Designed to handle the demands of marine two-stroke operation

Good To Know
Q: Should I replace bearings when installing this crankshaft? A: Yes, new main and rod bearings are recommended with any crankshaft replacement since old bearings may already show wear. Confirm bearing part numbers for your specific engine before ordering.
Q: Does this fit every 720 engine? A: Fitment depends on the watercraft model and serial number range, so verify compatibility against your machine before purchase. This assembly is listed for Sea-Doo GTS 720 models from 1997 through 2001.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
