Thanks Rick, So far I've removed the nut and large washer plate from the end of both seacocks and exposed the inner drum (yesterday) and sprayed liquid wrench liberally into the creases, into the drain/greasing plug holes, and I stopped up the seackocks from underneath the hull and sprayed intensively down both scuppers to coat the inside of the valve. I removed the handles and put a wrench on this morning and applied pressure and also banged with a rubber mallet to no avail.
There's simply no room in there to tap the end of the threaded part with anything. Some kind of compression jig would be ideal but I can't think of anything right now that would fit on there. I have a huge monkey wrench in storage that will probably break them free, or I can try the long pipe trick but I won't have a chance to do anything else until Sunday - will send an update then! Thanks for all the help guys!
