496 MAG / 496 MAG HO — FUEL INJECTORS

Which Fuel Injector Fits My MerCruiser® 496 Mag?

MerCruiser® 496 and 8.1L engine variants share related architecture but may differ by model, production range, and control system. Verify engine model, serial number, and existing OEM injector reference before ordering.

Find Your Engine Application

Match your engine model, year, and serial range below, then select the row to view the correct injector.

Not sure which part you need?

Confirm all four of the following before selecting a replacement injector.

1

Exact engine model

Confirm the full engine model designation from your data plate — for example, 496 Mag, 496 Mag DTS, 496 Mag HO, or 496 Mag HO DTS.

2

Engine serial number

Locate the serial number on your engine data plate. Serial range data for 496 Mag variants is verification in progress — confirmed serial ranges will be listed here once independently verified.

3

Existing OEM or injector number

If you have the OEM part number from the original injector or a service manual, compare it to 881693002 or its current supersession 8M0221353.

4

Physical injector characteristics

Connector type, body length, O-ring configuration and any visible markings can help confirm the injector family. Use physical characteristics together with OEM/serial verification, not as the sole method.

Have Your OEM Part Number?

Search your existing MerCruiser® OEM injector part number to find available aftermarket replacement options.
