Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket timing/cam chain made to cross-reference OEM part 420297086. Always confirm your engine serial number and model before ordering.

Q: Do I need any other parts when replacing the chain? A: Timing chain jobs often call for new tensioners, guides, and gaskets at the same time. Inspect those components and replace any that show wear.

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