Good To Know

Q: Does this timing chain fit my 2008 Sea-Doo Speedster 310? A: It is cross-referenced to OEM 420898044 for the 1503 engine fitted to that model year. Confirm your engine serial number and existing part number before ordering.

Q: Should the timing chain be replaced alone? A: On marine 1503 engines, chain guides, tensioners, and related hardware are commonly refreshed at the same time as the chain. Inspect those components during the job.

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