Good To Know

Q: Should I replace the tensioner at the same time? A: Yes, the guide and tensioner are commonly replaced together since both wear over the same service interval. Inspect the chain as well while the engine is open.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement that cross-references OEM part number 420236501 for Sea-Doo applications. Match the number on your existing guide 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.
