Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket fuel injector built to match OEM part 420874520. It is not manufactured or endorsed by Sea-Doo.

Q: How many injectors does my 1503 engine use? A: The 1503 is a multi-cylinder engine with one injector per cylinder, so confirm your build before ordering quantities. Replacing all of them at once is common practice during fuel system service.

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