MG Duff Volvo Penta DHP Cavitation Plate Anode

MG Duff CM3883728Z / CM3883728A Volvo Penta DHP Cavitation Plate Anode – Zinc / Aluminium

The MG Duff CM3883728Z and CM3883728A are sacrificial cavitation plate anodes designed for compatible Volvo Penta DHP marine propulsion installations. These replacement anodes help protect electrically connected underwater metallic components against galvanic corrosion.

The series is available in two sacrificial anode materials: zinc (CM3883728Z) and aluminium (CM3883728A). Both variants are identified as cavitation plate anodes for the specified Volvo Penta application and are sold individually.

When correctly installed with suitable electrical continuity, the sacrificial anode material corrodes preferentially, helping reduce galvanic corrosion of the metallic components requiring protection.

Available Variants

Volvo Penta DHP Compatibility

The MG Duff CM3883728 series is listed for compatible Volvo Penta DHP marine propulsion equipment requiring a cavitation plate sacrificial anode.

The supplied product information does not identify individual DHP configurations, production years or confirmed Volvo Penta original equipment part numbers.

Before ordering, verify the original anode shape, mounting position and compatibility with the specific Volvo Penta DHP installation.

Cavitation Plate Anode Construction

The CM3883728 series is identified as a cavitation plate anode intended for the corresponding mounting location on compatible Volvo Penta equipment.

The available specifications confirm the manufacturer part numbers, material options and application. Overall dimensions, weight, fixing-hole spacing and fastening specifications have not been provided.

These details should be checked against the existing anode or the MG Duff technical drawing before ordering.

Zinc and Aluminium Sacrificial Corrosion Protection

The MG Duff CM3883728 series is available in two sacrificial materials:

• Zinc – CM3883728Z: Commonly used for galvanic corrosion protection in saltwater marine environments.
• Aluminium – CM3883728A: Used in suitable marine corrosion protection systems, including saltwater and certain brackish-water applications.

When correctly mounted with suitable electrical continuity, the sacrificial material corrodes preferentially, helping reduce galvanic corrosion of electrically connected underwater metallic parts.

The appropriate material should be selected according to the vessel's operating water conditions and the Volvo Penta manufacturer's recommendations.

Inspection and Replacement

Inspect the cavitation plate anode periodically during routine marine propulsion system maintenance. Replace it when the sacrificial material becomes significantly depleted, physically damaged or no longer securely attached.

Before fitting a replacement, inspect the mounting surfaces, verify the original anode configuration and follow the applicable Volvo Penta maintenance instructions.
