Mercury – Aluminum Anode Plate | Corrosion Protection | 35–300HP Outboards & MerCruiser Drives | 76214T5

Overview

If your boat runs a high-rake propeller or performance setup, you need corrosion protection that fits without getting in the way. The Mercury Marine 76214T5 Aluminum Anode is a flat plate anode designed to fit neatly into the anti-ventilation plate cavity on a wide range of Mercury and Mariner 35–300HP outboards, as well as Force 90–100HP (1995 and newer) and MerCruiser Alpha One Gen II and Bravo I–XZ sterndrives. It provides the same galvanic protection as a traditional trim tab anode while offering more prop clearance — ideal for performance boats and demanding marine conditions.

Key Features

• Purpose: Protects your outboard or sterndrive from galvanic corrosion.
• Material: Cast from marine-grade aluminum alloy for long-lasting corrosion resistance.
• Design: Flat anode plate provides clearance for high-rake or performance propellers.
• Performance: Maintains strong electrical continuity for even corrosion protection.
• Durability: Works in both freshwater and saltwater applications.
• Ease of Use: Installs in place of a trim tab anode using existing hardware.

Engine & Boat Compatibility

• Mercury and Mariner 35–300HP outboards
• Force 90HP and 100HP outboards (1995 and newer)
• MerCruiser Alpha One Gen II
• MerCruiser Bravo I, II, III, X, XR, and XZ drives
• Suitable for both freshwater and saltwater environments

Performance & Real-World Benefits

The 76214T5 anode acts as a sacrificial barrier, preventing galvanic corrosion from eating away at your gearcase and drive components. Its flat profile allows clearance for high-performance props while offering full protection against electrolysis.

Made from Mercury’s proprietary aluminum alloy, it resists pitting and corrosion longer than zinc in most water types. A quick inspection and replacement when worn can save you from costly lower unit repairs and keep your outboard or drive running strong.

Why Choose Mercury OEM

The Mercury 76214T5 is a genuine Mercury Marine anode, precision-cast for an exact fit and optimal protection. Many aftermarket anodes use low-quality aluminum or recycled materials that corrode unevenly or too slowly, leaving parts exposed.

Mercury OEM anodes meet strict performance standards and military-grade alloy specs. They’re designed to work in harmony with your engine’s electrical system to provide consistent, balanced protection year after year.

FAQ

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

Q2: Can I use it in saltwater?
Yes — it’s made from high-quality aluminum, which protects well in both fresh and saltwater.

Q3: Why is it flat instead of tab-shaped?
The flat design provides extra propeller clearance, especially for high-rake or racing props.

Q4: How often should I replace it?
Inspect every few months and replace once it’s about half consumed or heavily pitted.

Q5: Why OEM over aftermarket?
Mercury’s OEM anodes use certified alloys and precise casting to deliver balanced, long-lasting corrosion protection.
