Specs At A Glance

Good To Know

Q: Do I need to replace all the injectors at once? A: Replacing a single failed injector is common, but if the others show similar age or contamination, servicing the full set keeps fuel delivery balanced. Always inspect the seals and O-rings when installing.

Q: Is this an original Sea-Doo part? A: This is an aftermarket fuel injector built for Sea-Doo applications and cross-referenced to OEM number 420874846. It is not an original factory part.

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