My concern was extended time in salt water. All the books I have say that bronze is the best below-water-line metal, and that bwl through-hull should only be bronze. My wife and I talked about putting our M-17 in a mooring, and before I do that, I would want to change the thru-hull arrangement. Aluminum will corrode in salt water, pit corrosion leading to eventual failure.
