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
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
pumps were switched off.
needless to say a walked away from the boat but it was a very expensive exercise.
