Crankshaft Assembly for Sea-Doo HX 720 1995-1997

Crankshaft Assembly for Sea-Doo

This crankshaft assembly is a complete rotating crank unit for Sea-Doo HX 720 two-stroke personal watercraft engines.

Overview

This crankshaft assembly is a complete crankshaft replacement for the Sea-Doo HX 720 two-stroke engine. It converts the up-and-down motion of the connecting rods into rotation that drives the PWC driveline, and it is intended for riders replacing a damaged, seized, or out-of-spec crank. Confirm your engine code and crank dimensions before ordering, since crank specifications differ across Rotax engine families.

Good To Know

Q: Does the crankshaft include the connecting rods? A: This listing is for a complete crankshaft assembly, which includes the connecting rods as part of the unit. Match the engine code on your machine to the 720 family before ordering.
