Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket fuel injector that cross-references OEM number 420874846, not an original factory part. It is built to match the fit and function of the original.

Q: How many injectors does my engine need? A: The 1503 engine uses multiple injectors, so check your model's setup before ordering. Replacing all of them at once is often recommended when one fails.

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