I think John and I are reading out of the same play book here, but the Groco valves in your photo have not been manufactured in about 20 years. There are no new parts available for them. Why they are in a 1996 model boat is a mystery. My boat was built in May, 1996 and it has the Conbraco-Apollo seacocks. My advice is to not mess with the Groco seacocks a lot until the boat is hauled out of the water. If you break a piece of the seacock, you going to be in trouble.
