805224A1 routes to current Mercury replacement 8M0239245

This IAC valve applies to the earlier EFI/TBI and 454 MAG MPI / 502 Magnum MPI engine families. It is NOT the correct IAC for the 7.4L L29, ECM-555, or 496/8.1L families — those use a different IAC architecture. Verify your exact engine model, serial number, and existing OEM part number before ordering.

The current 8M0239245 kit includes the IAC motor, mounting screws, and O-ring (25-808547). Verify kit contents with your supplier before ordering separately.

Verified Engine Applications

Application relationships are verified against Mercury Marine primary source documentation. Verify your exact engine model, serial number, and existing OEM part number before ordering.
