just need a little help understanding this (i know enough to be dangerous). i visited a
boat last weekend that seems to have some
electrolysis issues i.e. it states that it has had a new prop and prop shaft, and the new-ish zinks were the correct shape but crumbled when touched. so guessing they were fitted with the new shaft and prop and slowly in the
dock disintegrated the softer
parts and leaving a matrix. i also noted that none of the seacocks worked or the handles were turning loosely. The
boat had
water up to just under the floor boards (boards were rotten). none of the seacocks were bonded, i didn't see much evidence of bonding at all. so my understanding of the
electrolysis in boats is that the stray
current needs to conduct through something to ground. would the standing
water in the boat do this, i.e. loose wire in the
bilge, through the standing water through the through
hull and to ground causing damage? the boat was plugged in and the
charger active.
bilge pumps were switched off.
needless to say a walked away from the boat but it was a very expensive exercise.
