Sierra Ignition Coil 18-5494-2 for MerCruiser 350 MAG MPI 350/V-8 Engines

The Sierra 18-5494-2 is an ignition coil built for MerCruiser 350 MAG MPI 350/V-8 sterndrive and inboard engines. It supplies the high-voltage spark needed by the electronic ignition system to fire the spark plugs, and it is engineered to the fit and electrical output required by these specific MerCruiser engine calibrations.

This coil is application-specific to three MerCruiser 350 MAG MPI variants: the 1998 350 MAG MPI (GEN +) covering serial numbers L010019 through L325962, the 1998 350 MAG MPI MIE (GEN +) covering serial numbers L002008 through L302199, and the 350 MAG MPI SKI covering model years 1995-1998 with serial numbers F350583 through L304599. All three applications use the 350 cubic inch V-8 engine block. Because coverage is tied to a serial number range within each model year, confirm your engine's serial number against the ranges above before ordering.

The coil weighs 3.17 pounds and measures 13.8 x 4.4 x 4.4 inches. It is sold as a standalone ignition coil and is intended for boat owners and marine technicians performing ignition system maintenance or replacing a failed coil on a covered MerCruiser 350 MAG MPI engine.
