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!

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.

If you find out what New Found Metals would do a M-17 opening port for, be sure to post it here. I'm sure that there are many others like myself who would be interested.
