32' Big M on the Loop

[Roger2]

There is a Gas 32' "Big M" Currently on the Loop. I contacted him on the "AGLCA" site and got the following response.
He's on the hard @ Demopolis yacht Basin for winter, will resume trip in January.
He's asking what to do about salt water in his fresh water cooled engines.
I said to maintain anodes and flush with fresh water when possible.

I would like to pass on your suggestions also.
