Mercury – Quicksilver Engine Starter | Yamaha Series | Marine-Grade Construction | 8M6007419

Overview

There’s a certain comfort that comes with turning the key and hearing your outboard fire instantly to life. It’s a small moment, but if you’ve spent enough hours on the water, you know how big it feels.

Whether you’re easing out at dawn with glassy water ahead or loading up the family for a late-day cruise, you’ll feel good knowing your Yamaha outboard is supported by a starter built to keep up.

Performance & Practical Benefits

A good starter doesn’t draw attention to itself—it simply works. That’s exactly what you get with the 8M6007419. The permanent magnet design delivers strong torque without hesitation, helping the engine spin smoothly and catch quickly. You’ll appreciate the secure feel during those early-morning launches when the temperature drops or after a long day when the motor’s been sitting still.

The unit’s internal components are built to handle marine reality: heat, vibration, long idles, sudden acceleration, and plenty of moisture in the air. Its epoxy-sealed armature helps guard against rust and electrical breakdown, while the durable bushings support tight, steady rotation over thousands of starts. Installation is straightforward, especially for anyone familiar with Yamaha rigging, and the fitment is clean and precise.

Why Buy OEM

Choosing an OEM-grade Quicksilver starter is about more than replacing a worn part—it’s about removing uncertainty. Aftermarket imports might work for a while, but they’re rarely engineered to match Yamaha’s electrical requirements as closely as they should. This starter is built to the correct specification, meaning proper alignment, voltage draw, and engagement every time.

You’ll get:

• Proven durability backed by marine-specific engineering
• A starter made to perform right out of the box
• Long-term value and fewer repeat replacements
• Confidence that your Yamaha behaves exactly as the factory intended

When you’re miles from shore, that level of trust matters.
