John, probably the easiest solution is to cut the through-hull fitting 
below the gate-valve, and then cut the remaining through-hull fitting 
into two halves from the outside.  If you really want to save the 
existing through-hull fitting, you might try cutting some vertical cuts 
in the gate-valve, /almost/ all the way through, using a dremel tool. 
This might help it crack and let go of the through-hull.

This is a good time to remind everyone to check their 1/2" 
through-hulls.  If they're the ones that Whitby made with a pipe nipple 
peened over a fender washer, replace them right away.
