This is a throttle-body injection (TBI) component. TBI injectors are not interchangeable with multi-port injection (MPI) injectors. MerCruiser® engines of the same displacement may use TBI or MPI depending on production period and engine variant.
852956A1 is an earlier EFI/TBI throttle-body injector kit and is NOT an MPI injector. It applies to selected 4.3L EFI, 5.0L EFI, 5.7L EFI, 350 MAG EFI, and 7.4LX TBI variants. Do not order this part for MPI or ECM-555 engines. Verify your exact engine model, serial number, and existing OEM kit number before ordering.

Engine Applications

The following application relationships are based on Mercury/MerCruiser OEM where-used data. Serial ranges are exact as supplied — do not generalise across variants. Rows marked Verification in Progress lack complete year/serial data from OEM sources — do not infer missing boundaries.

Injector Identification / Cross-References

The following cross-reference information is based on Mercury/MerCruiser OEM kit data and specialist Motor Man research. The individual injector marking 17104288 is a specialist cross-reference associated with the 852956A1 kit — it is not a Mercury OEM supersession number. Do not treat this as a confirmed manufacturer part number.

Visual Identification

Visual identification details — body colour, connector type, and manufacturer markings — are under verification. Remove an existing injector and compare physical characteristics against confirmed OEM documentation before ordering.

What's Included

852956A1 is supplied as a matched pair of 2 TBI injectors. Package contents will be confirmed once a verified replacement product is sourced. Injector O-rings and seals are typically sold separately — inspect and replace as needed.

How to Verify Fitment

1

Confirm the full MerCruiser engine model designation from your data plate — not just displacement. EFI/TBI and MPI engines of the same displacement use different injector systems and are not interchangeable.

2

Confirm the model year and locate the engine serial number plate. Record the serial number and cross-reference it against the application table above.

3

Remove one existing injector and read the OEM kit number or individual injector marking stamped or printed on the body. The OEM kit number 852956A1 or individual injector marking 17104288 confirms this is the correct replacement.

4

Confirm the throttle-body configuration. 852956A1 is a TBI injector kit — do not order this part for multi-port injection (MPI) or ECM-555 engines.
