## 🔌 Function

Sacrifices itself to galvanic corrosion so the folding propeller and the drive metal around it are protected.

## ⚠️ Common Signs of Failure

-   Ring wasted to a fraction of its original thickness
-   No wastage at all, which points to a poor electrical bond
-   White powdery corrosion or pitting on the propeller and drive
-   Mounting face corroded, so a clean metal contact cannot be made
-   Fixings seized or corroded away
