Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket timing cam chain made to fit the listed Sea-Doo application and cross-references OEM 420898044. It is not manufactured or sold by Sea-Doo.

Q: Should I replace anything else at the same time? A: Timing chain jobs commonly call for a fresh tensioner and guides, so inspect those while the engine is open. Confirm your exact model and year before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
