Seachoice Anode Kit – Mercruiser Alpha One Gen II (1991 & Newer), Aluminum | Saltwater
This complete aluminum anode kit is designed specifically for Mercruiser Alpha One Gen II stern drives from 1991 and newer, used in saltwater and brackish water environments. It provides full corrosion protection across all anode positions on the drive, replacing every sacrificial anode in one convenient kit.
All components are cadmium-free and conform to Mil-Spec A-24779(SH). Aluminum anodes are the correct choice for saltwater and brackish water use, where they outperform zinc in electrochemical activity and provide more effective galvanic protection for the drive.

- 1 skeg anode for the ventilation plate

Parts Desk Insights
This kit is the right choice for owners of 1991 and newer Mercruiser Alpha One Gen II drives who operate in saltwater or brackish water and want to replace all drive anodes in a single purchase. The Gen II drive has more anode positions than the Gen I — six in total — so using a complete kit ensures no position is missed during service. Aluminum anodes are the preferred material for saltwater use, providing better galvanic protection than zinc in marine environments. Replacing all anodes at once is best practice for maintaining consistent protection across the drive. If you operate in freshwater, use the magnesium version instead: Seachoice Anode Kit – Mercruiser Alpha One Gen II, Magnesium. For 1984–1990 Alpha One Gen I drives, see the Seachoice Anode Kit – Mercruiser Alpha One Gen I, Aluminum and Seachoice Anode Kit – Mercruiser Alpha One Gen I, Magnesium.
