The Yanmar 196450-02601 is a high-performance magnesium split ring anode specifically designed for Yanmar saildrive units, including models SD20, SD25, SD30, SD31, SD40, SD50, and SD60. This two-piece "split" design is a significant maintenance advantage, as it allows for the replacement of the sacrificial anode without having to remove the propeller, a task that can even be performed underwater by a diver. Because it is composed of magnesium, this specific part is intended strictly for use in freshwater environments, where it provides the necessary voltage to protect the saildrive's aluminum housing from galvanic corrosion. The anode typically comes as a pair of halves with mounting screws included, and it is a direct superseding replacement for the older part number 196450-02600.
