Quicksilver OEM Fuel Injector

The Quicksilver/Mercury 879288A43 is a genuine OEM fuel injector engineered specifically for the MerCruiser 3.0L MPI (Multi-Port Injection) sterndrive engine. As an authentic Mercury Marine replacement component, it is manufactured to exact OEM specifications and carries a current part status, meaning it remains an active production part available through authorized dealers and distributors.

This fuel injector is a precision component within the fuel rail and drain system bracket assembly of the MCM 3.0L MPI engine. Proper fuel injector function is critical to maintaining accurate fuel metering, engine efficiency, and reliable performance on the water. Replacing a worn or faulty injector with a genuine OEM part ensures compatibility and maintains the integrity of the engine's fuel delivery system.

Because this is a special-order Mercury Marine part, buyers should be aware that additional warehouse handling time of 1–3 business days may apply depending on the retailer. It is important to verify fitment with your specific engine model and serial number prior to placing an order, as the item may be non-returnable once processed through some retailers. The part ships in new condition and is backed by Mercury's limited parts warranty when purchased through an authorized dealer.
