Specs At A Glance

Good To Know

Q: How can I be sure this injector fits my boat? A: Cross-check your engine's OEM part number against 420874430 before purchase. Matching the number and the 1503 engine confirms compatibility.

Q: Can I replace just one injector? A: A single injector can be replaced when the others test within specification. Many prefer replacing the full set so fuel delivery stays balanced.

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