Mercury – Quicksilver Aluminum Anode Plate | Corrosion Protection | Mercury, Mariner, Force & MerCruiser Drives | 76214Q5

Overview

Corrosion doesn’t take a day off — but with the Mercury Marine 76214Q5 Quicksilver Aluminum Anode Plate, your outboard or sterndrive gets constant protection. This flat anode fits the anti-ventilation plate cavity on Mercury and Mariner 35–300HP outboards, Force 90–100HP outboards (1995 and newer), and MerCruiser Alpha One Gen II and Bravo I, II, III, X, XR, and XZ drives. Its low-profile shape provides extra clearance for high-rake propellers, making it ideal for performance setups. Built from premium marine-grade aluminum, it sacrifices itself to corrosion so your engine and drive don’t have to.

Performance & Real-World Benefits

The 76214Q5 aluminum anode prevents electrolysis from eating away at your engine and drive components. Designed for high-performance applications, its flat profile gives propellers the clearance they need while still offering full corrosion protection.

Regularly replacing your anode keeps your gear housing, lower unit, and propeller hardware in top condition. Aluminum anodes provide better, longer-lasting protection than traditional zinc, especially in mixed or brackish water. It’s a simple maintenance step that can save you major repair costs down the line.

Why Choose Mercury OEM

The Quicksilver 76214Q5 is a genuine Mercury Marine part, designed and tested to meet the highest marine protection standards. Many aftermarket anodes use recycled aluminum or inconsistent alloys that corrode unevenly, leaving key areas exposed.

Mercury’s OEM anodes use a precise, military-grade aluminum blend that ensures balanced corrosion protection across your entire drive. When you choose Mercury, you’re choosing proven reliability backed by decades of marine engineering.

FAQ

Q1: What drives and engines does this anode fit?
It fits Mercury/Mariner 35–300HP outboards, Force 90–100HP (1995 and newer), and MerCruiser Alpha One Gen II & Bravo I–XZ drives.

Q2: Can it be used in both freshwater and saltwater?
Yes — it’s designed to perform equally well in fresh, salt, or brackish water.

Q3: What makes it different from a trim tab anode?
It’s flat for added prop clearance, ideal for high-rake props or performance setups.

Q4: How often should I replace it?
Inspect every few months and replace when more than 50% corroded or heavily pitted.

Q5: Why Mercury OEM instead of aftermarket?
Mercury anodes are built from certified aluminum alloys for consistent, even corrosion protection — something aftermarket versions can’t always match.
