Engineered Marine Products Ignition Coil for Evinrude Outboards, Cross Reference Sierra 18-5179 (300-01991)

The Engineered Marine Products 300-01991 is an ignition coil built for Evinrude outboard motors. It supplies the high-voltage spark needed to fire the spark plugs, and is a common wear item on outboard ignition systems where coils weaken or fail over time and cause misfires, hard starting, or a no-spark condition. The coil uses a male connector for a bolt-on installation, replacing the original unit without modification to the ignition harness. It measures 3 inches long, 3 inches wide, and 2 inches high, and weighs 0.356 pounds, making it a compact, direct-fit replacement sized to match the factory mounting location. This coil cross-references to Sierra part number 18-5179 and GLM part number 72010, so it is compatible with ignition systems calling for either of those numbers. Because ignition coils are wear parts, replacing a weak or failed coil with a properly matched unit like the 300-01991 restores reliable spark output and helps the outboard start and run consistently.
