Tom: I'm sure others have said so already, but brass ain't never gonna work. You never, never want to use brass below the waterline. It contains zinc, and it will "de-zincify: the zinc in the brass electrolyzes away, just like a sacrificial zinc. Brass can be useful aboard... I like to use brass pipe nipples to make drains, but they have to be well above the waterline. You want true marine-grade bronze. The folks at the foundry should be able to advise you. I've been thinking of asking the folks at new Found Metals what a M17-shaped opening port would cost in bronze!

M-owners:
Please include me in CB repair ideas. Our M-15 #175, Kestrel, has her CB jammed. Am planning to jack up next month and try to remove. According to my info, the ballast is/was lead shot but can't confirm. I don't see any rust stains or bleeding from the little I can see up the trunk.
Since the CB weighs about 75#, I will stop by a brass foundry in Salt Lake City and see if they can make a pattern and cut me a solid brass CB. Only maintenance after that will be with Brasso to keep it shiny for the fish to chase after.
Thanks for all the helpful info so far.
Tom
