Are you talking about the sacrificial zinc anodes near the screw? They are there to prevent the brass from literally being eaten by the seawater.

Interesting tidbit of info...thanks. had no idea that was even an issue, let alone the fix.

Sacrificial zinc anodes are almost universal on all boats with metal in contact with the water. It focuses corrosion on the zincs.

I am fascinated by the zinc plates. How exactly does this work?

Does it change the chemistry of the water? How does this work while the sub is moving and water is constantly being swept away?
