Performance & Real-World Benefits

This wire kit keeps your MerCruiser’s ignition system performing the way it should—strong, steady, and clean. You’ll notice quicker starts, smoother idle, and stronger pull through the midrange. The marine-grade insulation resists cracking and protects against corrosion from salt or humidity, so your spark stays sharp season after season. It’s an easy, factory-fit upgrade that helps your boat stay dependable every time you hit the water.

Why Choose OEM

Choosing Mercury Marine OEM parts means you’re using the same gear your engine was built with. Every Quicksilver wire set is tested for voltage balance, insulation strength, and resistance to marine wear. Aftermarket kits may fit loosely or use weaker materials that fail faster under heat or salt. With OEM, you get the perfect fit, the right performance, and the peace of mind that comes from genuine Mercury engineering.
