Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket tensioner guide made to fit the Rotax 1503 engine and matches OEM 420236501 dimensions.

Q: Should I replace the timing chain at the same time? A: If the guide failed or the chain shows wear or slack, replacing both together saves a second teardown.

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