If the valve was fully opened or closed little or no water

. Don't panic, you've got a long time before the boat sinks. Try to get some lubricant on the ball. Replace the stem. Attach the handle. Work the valve a few times and you should be good to go.
Here is the contact info for Forspar. Talk to them first and order the parts

Here is a neat gadget that takes a lot of the scary out of changing seacocks in the water.
Seabung Breach Control
Thanks Hopcar. That Seabung is a stroke of genius, but since I cannot open the valve I don't think I can push it through. I suppose I could pry it open but I think I will just put on a wetsuit and take a dive. I suppose a soft wooden plug
will work well enough? I will call Forespar and get more info and just change it out. My only concern is the thru-hull. It is likely old and I hope it doesn't crack. In regard to prying out the broken piece of the stem, no go. The stem on the body of the valve is male, the handle is female. So there is no stem left on the valve to grab onto...as far as I can see.
Really appreciate the help all, gives me confidence to take on this project
