Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket timing chain tensioner guide that cross-references OEM part 420236501. Confirm your engine code and model year before ordering.

Q: Should the guide be replaced on its own? A: Tensioner guides wear against the chain, so many technicians replace related chain components at the same time. Inspect the chain and tensioner while the engine is open.

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