Performance & Practical Benefits

The 816608Q82 wire kit brings your ignition system back to life. Each wire’s low-resistance core provides efficient voltage transfer, ensuring each cylinder fires strong and on time. That means smoother idle, improved acceleration, and more dependable starts — even after long layups or cold mornings on the water.

The heavy-duty red insulation resists cracking and fading under high heat, while the snug-fitting boots keep moisture and corrosion at bay. With the wires cut to exact OEM lengths, installation is easy — just replace one at a time, and you’re back in business.

Why Buy OEM

Mercury’s OEM wire kits are designed specifically for marine applications — not rebranded automotive parts. Every wire is tested for correct length, flexibility, resistance, and insulation integrity to handle salt spray, heat, and constant vibration.

Aftermarket sets can look similar but often miss on quality. The insulation breaks down faster, lengths don’t match perfectly, and electrical resistance can vary. A genuine Quicksilver wire kit ensures the exact fit, clean routing, and performance your engine was built for.
