This is very helpful, thanks.And make sure you have the correct amount of them. Protect everything. On the 28 Coasatal I take care of there are 2 on each shaft, 4 inch on the rudders and 3 inch on the trim planes and a underwatwer bonding plate was also installed. If a twin, make sure both motors are bonded together. Dont rely on the neg batteryconnections that are also supposed to be bonded together
No issues with any corrosion anywhere
