When it comes to reliable ignition, spark plug wires are the unsung heroes of your outboard’s performance. The Mercury Marine Spark Plug Wires - 8M0088014 are purpose-built to handle the demanding conditions your engine faces every time it leaves the dock — heat, vibration, moisture, and constant exposure to salt air.

Each wire is cut to the perfect length for select Mercury outboards, making sure they route cleanly without unnecessary slack or interference. The heavy-duty insulation protects against electrical leakage, while corrosion-resistant terminal ends ensure solid, uninterrupted contact — even after long hours in saltwater or high-humidity environments. Whether you’re chasing down a misfire or just swapping out aging wires, these factory-matched replacements restore the strong, consistent spark that keeps your engine firing clean.

Why they belong in your rig:

• Precision cut for proper fit and clean routing on select Mercury outboards
• Marine-grade insulation resists heat, water intrusion, and constant vibration
• Corrosion-resistant terminals ensure strong, reliable electrical contact
• Designed to deliver consistent spark for smooth acceleration and fuel efficiency

Ideal for:

1. Replacing worn or cracked spark plug wires to prevent misfires
2. Restoring ignition performance in high-hour engines
3. Ensuring reliable spark delivery in saltwater, freshwater, and mixed conditions

A strong spark makes all the difference — and with these Mercury plug wires, your engine gets exactly what it needs to fire strong every time you turn the key.
