MG Duff Volvo Penta 250 270 275 280 285 Dogbone Anode

MG Duff CM832598Z / CM832598A Volvo Penta 250 270 275 280 285 Dogbone Anode – Zinc / Aluminium

The MG Duff CM832598Z and CM832598A are sacrificial dogbone anodes designed for compatible Volvo Penta 250, 270, 275, 280 and 285 sterndrives. These replacement anodes provide corrosion protection for electrically connected underwater metallic components of the propulsion system.

The series is available in two materials: zinc (CM832598Z) and aluminium (CM832598A). Both versions are intended for the specified Volvo Penta sterndrive applications and are sold individually.

The characteristic dogbone anode configuration is an important identification feature when selecting a replacement. The anode must match the original component's shape and mounting arrangement.

Technical Specifications

Available Variants

Volvo Penta Sterndrive Compatibility

The MG Duff CM832598 dogbone anode series is specified for compatible installations of the following Volvo Penta sterndrive models:

• Volvo Penta 250
• Volvo Penta 270
• Volvo Penta 275
• Volvo Penta 280
• Volvo Penta 285

Before ordering, verify the original anode shape, mounting position and compatibility with the particular sterndrive configuration.

Production years and confirmed Volvo Penta original equipment part numbers have not been specified in the supplied product information.

Dogbone Anode Construction

The CM832598 series is identified by its dogbone-style sacrificial anode body, intended for the corresponding mounting position on compatible Volvo Penta sterndrives.

The supplied specifications confirm the anode configuration, material options and compatible drive models. Overall dimensions, weight, fixing-hole spacing and fastening specifications have not been provided.

Compare the original anode's shape and mounting arrangement with the replacement component before installation.

Zinc and Aluminium Sacrificial Corrosion Protection

The MG Duff CM832598 series offers two sacrificial anode materials:

• Zinc – CM832598Z: Commonly used for galvanic corrosion protection in saltwater marine environments.
• Aluminium – CM832598A: Used in suitable marine corrosion protection systems, including saltwater and certain brackish-water conditions.

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

Select the appropriate material according to the operating water conditions and Volvo Penta's recommendations for the specific propulsion system.

Inspection and Replacement

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

Before fitting the replacement, inspect the electrical contact surfaces and confirm that the dogbone body and mounting arrangement match the original component.
