Good To Know

Q: Do I need to replace the timing chain too? A: If the chain shows stretch or the guide is heavily grooved, replacing chain and guide together is the safer path. Inspect both once the cover is off.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement for Sea-Doo applications, cross-referenced to 420236501. Confirm your engine code and serial 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.
