So, I dropped into West Marine on Sunday to buy a new shaft zinc and found all they had were aluminum anodes. I guess the argument is that the aluminum lasts longer and is somewhat more environmentally sound.
Anyway - I have a zinc anode in my heat exchanger, so I think that would deteriorate quicker if I put aluminum on the shaft, so I went elsewhere and bought a zinc shaft anode.
I am wondering if there is any real benefit to switching to aluminum? And how hard is it to find an aluminum engine anode (I have a few years worth of zinc engine anodes in my toolbox)?
