I have one of these Gil Drive I brackets;
http://www.gilmarine.com/products/gb.../brackets.html
without the side platforms (which can be added) I picked this up several years ago and recently was going to use it on a project 23' Formula that was going to be converted to outboard. Ended up with very little time to work on it and lost storage facility. Bailed out of the project and sold it, but kept the bracket. I honestly don't know if I want to sell it right now. I'll give that some thought and depending on what I end up with for a new (to me) boat for next year, it may end up in the for sale forum. I'll give youz guys first crack at it for a good price (because I got a great deal on it) if that happens.
I just don't want it to end up like other things I've sold and later wished I hadn't. Know what I mean? ;) 8)
