805225A1 Mercury Marine Fuel Injector – Remanufactured OEM Replacement

Restore factory performance and smooth operation on your Mercury EFI marine engine with this remanufactured 805225A1 fuel injector, engineered for 5.7L, 6.2L, 454, 502, and 8.2L platforms.

Each injector undergoes a complete multi‑stage restoration process including ultrasonic cleaning, internal component replacement, and dynamic flow testing.
