I am a diver in san diego
and I have a customer who has a bizarre calcification issue under his boat. When I first picked up the account, I figured that it was residue of some previous electrical
issue. I cleaned the vessel and polished the shafts. The following service
, the shafts and props were coated with the same white chalky substance. In the 8 years that I have been diving
, I have never see such rapid calcification before. I figured that maybe the zincs were possibly dead. I polished the contacts and slapped new anodes on the zincs during the last service
. I came back to the vessel two days ago for the next service and the calcification problem persisted (Im sorry I keep calling it "calcification," it might not even be calcium). I checked out the zincs, and they were not even burning. In fact, the zincs had growth! Thats right, the zincs looked as though if I had just put them on and there was some stuff growing on them.
I was wondering if anyone might have an idea as to what might be going on under this boat. It is a 32' luhrs with two 1 1/4" shafts
