ARCO Marine Premium Replacement Ignition Coil f/OMC Inboard Engines

The ARCO Marine Premium Replacement Ignition Coil for OMC Inboard Engines is purpose-built for boaters who demand reliable starting and consistent engine performance on the water. Whether you're running a Volvo Penta inboard or a legacy OMC setup, a failing ignition coil can leave you stranded miles from the dock. This premium replacement addresses that critical vulnerability, restoring spark delivery and eliminating the frustration of hard starts, misfires, and unreliable idle that signal coil degradation.

Built to OEM specifications, the ARCO Marine coil generates the high-voltage secondary current needed to fire spark plugs with precision across the entire RPM range. The sealed housing protects internal windings from moisture and salt-spray corrosion—a critical advantage in marine environments where humidity and airborne salt accelerate electrical component failure. Its compact, durable construction ensures a direct fit without modification, and the unit weighs just 1.85 lbs, making installation straightforward for both professional technicians and experienced DIY boaters familiar with engine bay access.

This replacement coil serves boaters operating 1996-and-later Volvo Penta inboards and OMC-equipped vessels seeking OEM-equivalent reliability without premium pricing. It directly replaces OMC Ignition Coil 3854161 and 987680, as well as SIERRA Ignition Coil 18-7492 and CDI Electronics units, giving you multiple sourcing options in one proven product. Whether you're preparing for extended cruising season or performing preventive maintenance during off-season haulout, having a quality replacement coil on hand ensures you won't face unexpected electrical failures that compromise safety or enjoyment on the water.
