8.1L MPI / 496 — FUEL INJECTORS

Which Fuel Injector Fits My MerCruiser® 8.1L / 496?

The MerCruiser® 8.1L MIE and 496 Mag / 496 Mag HO engine families use OEM fuel injector 881693002, superseded to 8M0221353. Serial range data is sourced from the Mercury/Quicksilver application guide. Verify your engine model and serial number before ordering.

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.
Fitment Notice: MerCruiser engines of similar displacement may use different fuel injectors depending on engine model, production year and serial range. Verify your OEM part number, engine application, serial number and relevant injector characteristics before ordering. Contact us before purchase if you are uncertain about compatibility.

Always Verify Before Ordering

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, 8.1L MIE, 8.1L HO MIE, 496 Mag, 496 Mag HO, 496 Mag DTS, or 496 Mag HO DTS.

2

Engine serial number

Locate the serial number on your engine data plate. Serial ranges from the Mercury/Quicksilver application guide are listed in the table below.

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.
