Mercury – Engine Starter | Yamaha Outboard Series | 12-Volt Marine Grade | 8M6007417

Overview

There is a certain comfort that comes from turning the key and hearing your engine spring to life without hesitation. No grinding. No sluggish turnover. Just a clean, confident start that tells you your day on the water is off to the right beginning. The Quicksilver 8M6007417 Engine Starter delivers that feeling every time — the kind of reliability you appreciate whether you are heading out before sunrise or docking after a long run.

Boaters know that when a starter fails, it never happens at a convenient moment. That is why a dependable replacement matters so much. This starter is built for Yamaha outboards that have seen real time on the water, giving them the strong, steady crank they need to fire up quickly and run smoothly.

Key Features

• Designed for Yamaha outboards rated at forty to fifty horsepower
• Permanent magnet direct drive for high efficiency and consistent starting power
• Twelve-volt motor with counter clockwise rotation
• Nine-tooth gear engineered for precise engagement
• High temperature epoxy armature protects wiring from heat and corrosion
• Built with ninety percent copper bushings for long service life

Engine & Boat Compatibility

• Fits select Yamaha forty horsepower and fifty horsepower outboards
• Compatible with engines using Hitachi S108-99 and related starter assemblies
• Works well on center consoles, small fishing boats, skiffs, and lightweight runabouts
• Ideal for boats that require strong cranking power in tight, shallow-water conditions

Performance & Practical Benefits

A smooth start sets the tone for the whole outing. With this starter installed, you will feel that strong, steady crank right away. The permanent magnet design provides reliable torque without draining the battery, and the gear engagement feels crisp rather than harsh. Everything about the motion is clean and confident.

In everyday use, the difference is noticeable. Cold mornings, long idle periods, or back-to-back stops throughout the day — this starter handles them without complaint. The copper bushings help it run smoothly under load, while the epoxy-coated armature keeps the internal wiring protected from heat, humidity, and the constant vibration that comes with marine life.

Installation is straightforward, especially if you are replacing an older Yamaha or Hitachi unit. Bolt holes line up cleanly, electrical connections are simple, and once it is in place, you can trust it to hold up season after season.

Why Buy OEM

An OEM-grade starter is an investment in peace of mind. Aftermarket versions may save a little up front, but they often struggle with torque consistency, internal wear, and premature failure.

With this Mercury Marine part, you get:

• Reliability that matches or exceeds the original Yamaha starter
• Components tested for real marine conditions
• Longer service life thanks to stronger materials
• A clean, exact fit for faster installation
• Performance you do not have to second-guess

For boaters who want their engine to start the first time — every time — OEM is the simple, smart choice.
