MG Duff CM43396Z Mercury MerCruiser Zinc Block / Waffle Anode 0.66 kg
The MG Duff CM43396Z is a zinc block / waffle sacrificial anode designed for compatible Mercury and MerCruiser marine propulsion installations. Weighing 0.66 kg (660 g), it serves as a replaceable corrosion protection component for electrically connected underwater metallic parts.
The anode features a block / waffle-style construction intended for marine installations requiring this type of sacrificial anode. Manufactured from zinc, it provides galvanic corrosion protection by corroding preferentially when correctly installed with suitable electrical continuity.
The MG Duff CM43396Z is sold individually and can be identified by manufacturer part number CM43396Z and EAN 0628309100513.

Mercury and MerCruiser Application
The MG Duff CM43396Z is identified for use in compatible Mercury and MerCruiser marine propulsion installations requiring a zinc block / waffle anode.
The supplied product information does not identify specific engine models, drive generations, production years or original equipment part numbers.
Before ordering, compare the existing sacrificial anode with the MG Duff CM43396Z configuration and confirm the required mounting arrangement.
Block / Waffle Anode Construction
The CM43396Z features a block / waffle-style zinc body intended for the corresponding marine anode mounting application.
The specified weight is 0.66 kg. Overall dimensions, fixing-hole positions and fastening hardware specifications have not been provided in the available product information.
These measurements should be verified against the original component or the manufacturer's technical drawing before selecting a replacement.
Zinc Sacrificial Corrosion Protection
Zinc is commonly used as a sacrificial anode material in saltwater marine corrosion protection systems.
When correctly installed with suitable electrical continuity to metallic components requiring protection, the zinc corrodes preferentially, helping reduce galvanic corrosion of the electrically connected underwater parts.
The suitability of zinc depends on the vessel's operating water conditions and the requirements of the existing corrosion protection arrangement.
Inspection and Replacement
Inspect the block anode periodically during routine marine propulsion 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 and verify that the new anode matches the original component and installation requirements.
