We have an old 32 Woody here. I have been disconnecting various thru hulls from the bonding system due to deterioration and salt formation around the fittings. I see I am getting the same now around the swim step brackets and their mounting bolts, and also the fitting where the exhaust hose passes thru the transom. I neutralize the deposits with vinegar, flush with water, but the deposits return. Should I disconnect the bonding to the swim step brackets? I have a set of ZINC-2 plates sanwitched on the bronze rudder, and a 1 1/2” close clearance zinc on the shaft space between the stern bearing housing and prop. Those are my only zincs so I do not think I’m over zinc’d. There is a shaft brush, and a pigtail on the rudder shaft, that tie everything together. The shaft is Stainless steel. I know there are a lot of different opinions on bonding a wooden boat.
