Thanks for the replies... if it were August, I'd not hesitate to do the in-the-water-plug-it routine, and proceed from there. But the water temperature is in the low 40 degrees F, too cold for me. Hiring a diver is how I would approach that angle, given it is now December.
I have winterized both the speedo and depth transducers and let me tell you, it gets VERY exciting when the gusher starts... one has to work very fast! The risk of cross threading (or worse, having miss identified the correct thread size!), the water all over the interior, and the difficulty of getting tools into the space, all argue against a full blown attempt to replace the faulty valve while still afloat.
My thought was to plug the ball valve from the inside as follows: replace the existing hose (as quickly as possible!) on the ball valve's hose barb with a longer one, one that comes above the water line, then push a wad of underwater epoxy putty down the hose with a close fitting dowel, into the top of the ball valve's hose barb. That would limit the amount of sea water in the assembly to just about the same as there would be with a functioning, closed, ball valve. Finally, I would fill the hose with anti freeze, just in case the epoxy seal isn't 100%.
