Good To Know

Q: How do I confirm this injector fits my watercraft? A: Match the part number 420874430 and the 1503 engine listed for your year range before ordering. Serial number differences can affect fitment, so verify against your machine.

Q: Should I replace one injector or all of them? A: Replacing the set can keep fuel delivery even when the others are original and aged. A single replacement is fine when only one unit has failed.

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