ARCO Marine Premium Replacement Ignition Coil f/Mercury Outboard Engines 1998-2006

The ARCO Marine Premium Replacement Ignition Coil for Mercury Outboard Engines (1998–2006) is the reliable spark generator your boat depends on when you're miles from the dock. Whether you're running a multi-engine rig or a single-outboard setup, ignition coil failure is one of the most frustrating mid-water failures a boater can face—and this OEM-quality replacement ensures you get back to fishing or cruising without extended downtime. Built to exact Mercury specifications, this coil restores predictable, consistent ignition timing across your engine's RPM range.

An ignition coil transforms your engine's low-voltage electrical signal into the high-voltage spark needed to fire your spark plugs—and performance directly affects fuel economy, throttle response, and cold-start reliability. ARCO Marine's premium construction uses durable insulation and high-quality windings that withstand salt spray, vibration, and thermal cycling inherent to outboard operation. The compact 4 x 3 x 4 inch form factor integrates seamlessly with Mercury's ignition architecture, requiring no modification or adapter hassles during installation.

Mercury outboard owners running 1998–2006 models—especially those in saltwater environments or high-hour commercial operations—benefit most from proactive ignition coil replacement when performance dips or starting becomes sluggish. If your engine hesitates at mid-range throttle, struggles in cold conditions, or shows signs of misfiring, this drop-in replacement eliminates guesswork and restores manufacturer-spec ignition performance. Installation takes minimal technical skill and standard tools; consult your Mercury service manual for exact mounting location on your specific model year.
