In a bonded system the rig is in electrical

block, the block is in electrical
contact with the transmission
, the transmission
with the prop shaft and the prop shaft with the prop. Therefore, a zinc hanging over the side but wired to the rig will protect the prop and shaft. Not very effectively perhaps, but it will work. This arrangement should be used as additional protection only. It should not be relied upon as the sole means of protection from corrosion
