MG Duff 76214-5 Mercury Bravo III / Verado Round Plate Anode Ø92 mm

MG Duff CM762145 Mercury 76214-5 Bravo III / Verado Round Plate Anode Ø92 mm – Zinc / Aluminium

The MG Duff CM762145Z and CM762145A are circular sacrificial plate anodes designed for compatible Mercury outboard and MerCruiser sterndrive installations. Listed applications include MerCruiser Bravo III from 2004 onwards, Mercury Verado 6-cylinder engines and Mercury Alpha configurations.

The anodes correspond to the supplied Mercury part reference 76214-5, identified with a threaded mounting hole.

Two sacrificial materials are available: zinc (CM762145Z) and aluminium (CM762145A). Both versions measure 92 mm in outside diameter and 24 mm in height, with a single 7/16-14 UNC threaded fixing hole.

The zinc version weighs 0.33 kg, while the aluminium version weighs 0.13 kg. Both provide replaceable sacrificial corrosion protection for electrically connected underwater metallic components.

Technical Specifications

Available Material Variants

Both variants share the same specified outside diameter, height and mounting thread. Their weights differ according to the anode material.

Mercury and MerCruiser Compatibility

The MG Duff CM762145 series is listed for the following marine propulsion applications:

• MerCruiser Bravo III (Bravo 3) – 2004 onwards
• Mercury Verado – 6-cylinder engines
• Mercury Alpha – compatible configurations using the specified circular plate anode

The supplied Mercury part reference is 76214-5, described as having a threaded mounting hole.

The available information does not specify individual Alpha generations, engine serial number ranges or additional OEM numbers. Confirm compatibility against the existing anode and the applicable Mercury or MerCruiser parts documentation.

Circular Plate Dimensions and Mounting

The CM762145 series features a round sacrificial anode body with one threaded fixing hole.

• Outside diameter: 92 mm
• Height: 24 mm
• Number of fixing holes: 1
• Mounting thread: 7/16-14 UNC
• Specified bolt length: 1 3/4 inch

The 7/16-14 UNC specification identifies the threaded mounting connection. The stated 1 3/4-inch bolt length is a mounting hardware specification and does not confirm that a bolt is supplied with the anode.

Before installation, compare the replacement with the original plate anode and verify thread compatibility and available mounting clearance.

Zinc and Aluminium Sacrificial Corrosion Protection

The MG Duff CM762145 series is available in two sacrificial materials:

• Zinc – CM762145Z: Weighs 0.33 kg and is commonly used for galvanic corrosion protection in saltwater marine environments.
• Aluminium – CM762145A: Weighs 0.13 kg and is used in suitable marine corrosion protection systems, including saltwater and certain brackish-water conditions.

When correctly installed with suitable electrical continuity to metallic components requiring protection, the sacrificial material corrodes preferentially, helping reduce galvanic corrosion of electrically connected underwater parts.

Select the appropriate anode material according to operating water conditions and the recommendations of the propulsion equipment manufacturer.

Inspection and Replacement

Inspect the circular plate anode periodically during routine outboard or sterndrive maintenance. Replace it when the sacrificial material becomes significantly depleted, physically damaged or no longer securely attached.

Before fitting a replacement, confirm the original anode diameter, height, mounting thread and drive configuration. Inspect the electrical contact surfaces and follow the applicable Mercury or MerCruiser installation instructions.
