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????


It's generally zinc for sal****er and magnesium sp for fresh water.

I run an aluminum boat in both fresh and salt water. I just replace my
zincs when they look bad.
