TOPIC: Need Help!

I've got a personal watercraft, possibly one of the first SeaDo type boats. Fiberglass 2 piece body. Top and bottom. Molded seat 2 person one behind the other. Outboard motor mounted inside the rear. About 6/7 foot long. Bowtie steering wheel turns two rudders. Think it was made in the 60's, possibly in Michigan. I think I found info and photos on this site or links to it a few years ago. Lost the info I had. Can anyone help me find it again, head me in the right direction? It's complete and I've finally got time to restore it. Thanks, for any help, Mike. Hope to stir things up a little. I found a note I had written! "Sting Ray- by Marine Unlimited of Warren, Michigan". Still can't find anything-- Google. So Helllllp!
