Good To Know

Q: Is this a genuine Sea-Doo injector? A: It is a replacement fuel injector cross-referenced to OEM part 420874430, not a factory-branded part. Match the number to your machine before ordering.

Q: Will one injector fix a misfire? A: A single fouled injector can cause a misfire, but the 1503 engine runs one injector per cylinder. Test each cylinder to confirm which injector needs replacing.

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