My P-bracket (Bronze) has a bonding wire back to the engine. Now I found corrosion at the engine block attachment of the wire. That made me think about the whole setup: The shaft runs in a cutless bearing. Now if I bond in the p-bracket I am actually only then creating a battery with steel and bronze connected through a wire and the saltwater acting as electrolyte. I am tempted to snap of the wire ??? Any thoughts.
