Tecnoseal Mercury Alpha 1 Gen 1 Magnesium Anode Kit

Tecnoseal offers this magnesium anode kit for the first-generation Mercury Alpha 1 sterndrive. Its contents are one 00806BISMG anode, one 00800MG anode and two 00807MG anodes. That four-piece combination is specific to the Gen 1 arrangement and should not be confused with the different Alpha 1 Gen 2 kit. It provides the individual pieces needed to service several protected areas of the compatible drive.

All four anodes are supplied together, and installation hardware is included. Magnesium is often the alloy of choice for freshwater use when specified by the drive manufacturer. The individual shapes and part numbers matter because a kit with the wrong generation or mounting pattern will not be a proper substitute. Check the drive identification before ordering.

During replacement, inspect each mounting surface and remove corrosion that could interfere with metal-to-metal contact. The anodes are intended to wear away while helping protect the connected underwater hardware. Their condition should be monitored as part of regular lower-unit maintenance, especially after extended time in the water. Explore more marine anodes for other sterndrive generations.
