Overview

A clean, steady spark starts with a strong connection. The Quicksilver 813715A1 Ignition Wire Kit restores reliable spark transfer between your coil and spark plug — helping your outboard fire up fast, run smoother, and stay dependable trip after trip.

This 9-inch OEM ignition wire is built for Mercury and Mariner outboards, designed to handle heat, vibration, and moisture without losing conductivity. If your old wire’s cracked, brittle, or showing signs of arcing, this direct-fit replacement brings back the solid ignition performance your engine was meant to have.

Performance & Practical Benefits

Over time, ignition wires take a beating from heat, salt, and vibration — all of which can weaken spark delivery. The 813715A1 wire kit restores full conductivity, ensuring your engine fires cleanly on every stroke. The high-dielectric insulation keeps energy focused on the plug tip instead of leaking or arcing to ground.

The wire’s fixed spark plug end provides a secure, moisture-tight connection, while the included coil-end adapters make installation quick and straightforward. Whether you’re fixing a misfire or refreshing your ignition system, this OEM wire brings back the steady spark your motor depends on.

Why Buy OEM

Mercury’s OEM ignition parts are engineered for the marine environment — constant vibration, heat, and exposure to water. Aftermarket wires often use lower-grade materials that can break down, stiffen, or fail prematurely.

With genuine Quicksilver parts, you’re getting the exact resistance, connector design, and wire flexibility your outboard was designed for. That means better performance, less electrical noise, and long-term reliability you can count on.
