Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket timing chain made to cross-reference OEM 420898044, and it is not produced by Sea-Doo.

Q: Should the chain be replaced alone? A: On a 1503 timing job it is common practice to inspect the tensioner and guides, and replace any worn components at the same time for reliable results.

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