Hmmmmm. your query brings up a question that I need answered too.

If I remember correctly, the anode ( rust-preventive sacrificial anode) that
is on every engine MAY be a different alloy for Sal****er versus Freshwater.
I'm doing the opposite of you. I am moving a 16 ft. Carolina Skiff from the
Texas bay system to my place in Lake Geneva, Wisconsin. Perhaps I should be
changing the anode coincident with that move???

Anyone know the answer????
