420874430 Fuel Injector for Sea-Doo Utopia SE 205 1503 2006

Fuel Injector for Sea-Doo

This fuel injector for Sea-Doo is a direct replacement for OEM part 420874430, built to feed the 1503 engine the accurate fuel charge it needs for steady power.

Overview

This fuel injector for Sea-Doo fits the 1503 engine found in Utopia and SE 205 models, delivering fuel in the spray pattern and volume the ECU is calibrated for. When an injector clogs or fails, the engine runs rough, loses power, or throws a fault, so a fresh unit gets the boat running right again. It is aimed at owners and shops servicing 2006 Utopia and SE 205 watercraft who want reliable fueling without OEM pricing.

Good To Know

Q: Can I replace just one injector? A: Yes, a single faulty injector can be swapped on its own, though servicing the whole set is common for balanced fueling. Match the removed injector to the part number shown here before ordering.

Q: Should I replace the seals too? A: New seals are advised whenever an injector is pulled and reinstalled to avoid leaks. Check the fuel rail and connector for wear while the system is open.

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