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.

Unless your boat is moored for some time in the water it really doesn't mater
much. If you just launch in the AM and recover in the PM and dry store the
boat in between outings you arn't likely to have galvanic corrosion issues.
Your original annodes could last for years! But keep an eye on things to be on
the safe side.

Lots of bass boats run in brackish water. Most of the lower Sacramento
Delta is brackish.
