Re: Seized seacock
If it's a tapered valve, a little heat is a good idea to expand the outer casing as mentioned already. You can also back off the tightening nuts until they get to the top of the thread (to protect the threads) and tap the valve out. Make sure you use some something SOFTER than the bronze. I use an old 5# lead solder ingot. The mass of something like this works wonders. Wood is also good but not as good as lead or a brass drift. Most of the time it does not take much tapping but if really stuck, don't pound so hard as to deform the shaft/nuts. Of course if the hull is a cored hull or just modern-thin, don't do this at all.
