MG Duff CMALPHAKITA MerCruiser Alpha One Gen II Aluminium Anode Kit 1991+

MG Duff CMALPHAKITA MerCruiser Alpha One Gen II Aluminium Anode Kit 1991+

The MG Duff CMALPHAKITA is an aluminium sacrificial anode kit designed for Mercury/MerCruiser Alpha One Generation II (Gen II) sterndrives manufactured from 1991 onwards. The supplied compatibility information specifies serial number applicability beginning at 0D469829.

The kit contains six sacrificial anode components and one fixing kit, providing replacement anodes for compatible Alpha One Gen II sterndrive installations. Aluminium serves as the sacrificial material, helping protect electrically connected underwater metallic components against galvanic corrosion.

The MG Duff CMALPHAKITA is cross-referenced with Tecnoseal KITALPHAONE/AL. Additional material versions are available under MG Duff part numbers CMALPHAKIT (Zinc) and CMALPHAKITM (Magnesium).

MerCruiser Alpha One Gen II Compatibility

The MG Duff CMALPHAKITA is intended for MerCruiser Alpha One Generation II sterndrive units manufactured from 1991 onwards.

• Drive Type: Alpha One Generation II (Gen II).
• Production Years: 1991 and newer.
• Serial Number Starting Point: 0D469829.
• Additional Serial Range Listed: 0D469859 – 1A999999.

The source lists both a starting serial number of 0D469829 and an additional range beginning at 0D469859. These values should be checked against the specific sterndrive serial number and applicable parts documentation before ordering.

Important: This kit is specified for Alpha One Generation II and should not be treated as interchangeable with Alpha One Generation I anode kits without confirmation.

Available Anode Materials

The MG Duff Alpha One anode kit range includes the following material options:

The appropriate sacrificial anode material should be selected according to the vessel's operating water conditions and the sterndrive manufacturer's recommendations.

Sacrificial Corrosion Protection

The aluminium anodes are intended to help protect electrically connected underwater metallic components of compatible Alpha One Gen II sterndrives against galvanic corrosion.

When correctly installed with suitable electrical continuity, the sacrificial aluminium material corrodes preferentially to help reduce corrosion of the protected components.

The kit provides multiple replacement anodes for the specified sterndrive system, allowing worn sacrificial components to be renewed during routine maintenance.

Installation and Maintenance

Before installing the MG Duff CMALPHAKITA, confirm the sterndrive generation, serial number and compatibility with the existing anode arrangement.

The kit includes one fixing kit. Installation should follow the applicable MerCruiser maintenance instructions, with mounting surfaces and electrical contact points checked as part of the replacement process.

Inspect the sacrificial anodes periodically and replace them when significantly depleted, damaged or no longer securely attached.
