There use to be one in Mobile somewhere. Not sure if they are still there or want the name is. What exactly are you looking for? There are a lot single boat junk yards around.
There is a place downtown called the Salty dog or something like that. It is on the road going to the shipyard from Garden street just before the little bridge heading towards Navy. Just a little hole in the wall, but has a bunch of used equipment from salvaged boats.
flounderpounder.com sell salvage part on internet,and in mobile outboard recyclers,but they went wholesale only a couple years back so you have to know someone thats buys from them or someone that works there.but if you need something the guy that works on my motor works there send me a message.
