MerCruiser® 8M0239245 Idle Air Control Valve
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.
Aftermarket cross-reference: Sierra 18-7632-1 — aftermarket replacement cross-reference. Verify fitment by engine model and serial number before ordering. Sierra part numbers are aftermarket references only and are not Mercury OEM numbers.
