Mercury – Alternator | 55 Amp Charging System | Marine-Grade Aluminum Build | 8M6007472

Overview

On the water, reliability is everything. When you turn the key on your Honda outboard, you want the engine to leap to life with the same steady confidence you feel as you ease out of the marina. The Quicksilver 8M6007472 Alternator delivers that peace of mind every time, keeping your electrical system strong and your boat ready for whatever the day brings—long trolling runs, electronics-heavy setups, or hours cruising between coves.

There’s comfort in knowing your charging system never struggles, never hesitates, and never leaves you guessing. That kind of trust is what separates an enjoyable day on the water from one filled with worrying glances at the voltmeter.

Key Features

• 12-volt, 55-amp alternator designed for Honda 115–130 horsepower outboards
• Internal regulator and internal fan for clean, efficient charging
• Built with plated hardware, pulleys, and fans to resist corrosion in harsh marine conditions
• Includes marine-rated flame arrestor screens that meet SAEJ1171 standards
• Engineered to meet or exceed original performance output
• Designed for straightforward installation with standard tools

Engine & Boat Compatibility

Ideal for boaters running Honda outboards in the 1999–2014 range, including:

• Honda 115 horsepower outboards
• Honda 130 horsepower outboards
• Boats relying on consistent electrical loads such as center consoles, pontoons, cuddy cabins, and trolling setups

If your rig runs a Honda 115 or 130 from this era, this alternator is built to fit, perform, and last.

Performance & Practical Benefits

This alternator delivers a smooth, steady charge that keeps your battery systems healthy and your accessories running without strain. You’ll notice stable voltage even when you’re running multiple electronics—GPS, fish finders, pumps, lights, stereos, or trolling motors.

The internal fan keeps the alternator running cool, extending its life while handling the constant demands of marine use. The corrosion-resistant design means it stands up to spray, humidity, and long saltwater seasons without losing integrity.

Most boaters describe the difference as subtle but unmistakable: steadier idle behavior, stronger starts after long drifts, and the quiet confidence that your battery isn’t slowly sagging.

Why Buy OEM

When experienced boaters talk about avoiding headaches, this is exactly the kind of part they mean. Choosing an OEM-grade Mercury Marine part gives you:

• A perfect fit for Honda outboards—no guesswork, no rewiring
• Long-term reliability engineered specifically for marine demands
• Better durability than bargain aftermarket units
• Protection from electrical faults caused by inconsistent charging
• A part that performs exactly as your engine expects, right from the first start

It’s the type of decision seasoned boaters make because it saves money, time, and frustration in the long run.
