Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket replacement tensioner guide that cross-references OEM part number 420236501. It is built to fit the listed 1503 engine applications.

Q: Should this be replaced on its own? A: Tensioner guides are often serviced alongside the chain, tensioner, and related hardware during a rebuild. Inspect all timing components before reassembly so nothing worn goes back in.
