I once had a teacher who said "The only stupid question is the one you don't ask". Since I've been bitten in the stern by questions I didn't ask, I'm going to look like a nautical idiot but I have to ask...

If I sail on an inland mud puddle, do I need zincs? I've read several postings on the deterioration and replacement of them. I've had "Itza Dew Sea" in the water for 4 seasons (hauled in the winter) but I've never seen or installed any zincs. Am I missing something important? (wouldn't be the first time) Or is this a salt water thing?

Thanks in advance for all your C-25 wisdom!

"Zincs" are a salt water thing.

For fresh or brackish water I believe aluminum or magnesium "zincs" are used.

The only zincs I have on my salt water boat are installed on the leg of my outboard, but since it doesn't make much sense to put aluminum on aluminum, I'd guess that magnesium "zincs" (which are less noble than aluminum) would be the way to protect your outboard in fresh water.

If I had a diesel or saildrive unit I'd look into this more carefully.
