Re: [Amel Yacht Owners] Prop Shaft Electrolysis
That looks awful.
I use a galvanic isolator on my AC circuit and also have the pedestal turned on only one day a week. So far in 3 months in the marina in the Caribbean I have used one kilowatt of electric.
There is a small zinc on the line cutter, and of course the 2 big ones on the rudder.
I am very sorry for the condition of your prop shaft. I believe there should be a drawing of your c drive in the owners manual . I believe replacing the shaft is a big project. It is also possible that a neighbor is putting AC into the water.
Did you have the marina check your AC outlet on the pedestal and the water around your boat?

I have just hauled Kristy out to repaint the bottom after 2 1/2 years.
She's been sitting in the water in a marina at Brunswick GA for the last 2
years where I've hired a diver to clean the bottom and replace the zincs as
needed every 4-6 weeks. I was surprised to see no zinc on the prop when
we hauled out, and dismayed to see severe electrolytic corrosion of the prop
shaft when I started changing the seals. I posted a pic at the KristySM243
