Mercury – Alternator | Heavy-Duty Industrial & Marine Series | Corrosion-Resistant Finish | 8M6007512

Overview

When you depend on your equipment day after day—whether you are running a commercial boat, working an industrial site, or hauling with a heavy truck—you need electrical power you never have to second-guess. The Quicksilver 8M6007512 Alternator brings that kind of certainty. It is the steady heartbeat behind ignition, electronics, pumps, lights, and every system that counts on clean, reliable output. There is a comfort in knowing your alternator will hold strong when the workload spikes or the weather turns rough, and that confidence is exactly what this unit delivers.

With its 160-amp output and rugged build, this alternator is designed for long service life in environments that punish lesser components.

Key Features

• High-output 12-volt, 160-amp alternator
• Internal regulator with external fan design for consistent cooling
• Plated hardware, fans, and pulleys for corrosion resistance
• Marine-grade flame arrestor screens meeting SAE J1171 certification
• Heavy-duty construction suitable for marine, industrial, and truck applications
• Wiring harnesses included where required for easier installation

Engine & Boat Compatibility

The Quicksilver 8M6007512 is built for demanding systems, including:

• Heavy truck engines requiring stable high-amperage charging
• Industrial engines used in generators, pumps, and machinery
• Marine engines operating in corrosive, high-humidity environments
• Compatible replacement for multiple Cummins, Delco, Motorola, and International alternator models

Works well on boats such as:

• Workboats and commercial vessels
• Utility barges
• Engine-intensive fishing boats
• Marine industrial platforms

Performance & Practical Benefits

This alternator is built for situations where electrical load is never light. The 160-amp output keeps batteries charged during heavy accessory use—GPS systems, lighting banks, pumps, hydraulic controls, or winches. The cooling fan and internal regulator work together to keep output smooth and heat in check, even on long, high-demand days.

The plated hardware resists the salt creep and moisture that often take out lesser alternators long before their time. You will notice the steadiness right away: no dimming lights when a pump kicks on, no fluctuating voltage when you throttle up, and no hesitation when starting after long hours of operation. It is engineered to handle vibration, heat, and moisture—three things that quickly expose weak charging systems.

This is the kind of part you install once and trust for years.
