This had happened in a matter of  weeks and at first the cause was a mystery. We tested the boat, the electrical systems, the mooring, the water, the piles, the river bed and then the anodes – the machinery had been just serviced and freshwater magnesium anodes fitted instead of salt water zinc anodes. The result accelerated degradation from corrosion and two new stern drives.

Always check your anodes are suitable for the home mooring water conditions – Salt = Zinc. Brackish = Alluminium. Fresh = Magnesium.  If in doubt, contact Boatcare Yacht Surveys.
