Gas line shut off valve

[LONAO]

Our 1975 Eska 5.5 HP outboard has a gas shut off valve that has stripped out. no gas leaks, but I can't turn the brass stem without destroying it. It looks like something that would be a standard part, but I don't have a clue where to start to find it - short of a marina boat repair shop... Any help out there?

I use these guys alot, they have the gas valves, I like to email and make sure I'm getting what I need. There always a pleasure to do business with, but there are other sellers out there.
