I have one on a 25' CC Proline offshore boat and love it. Also had one on a 21' CC Proline before the 25'. Both were original from the factory. The 21' had as much room as a friends Robalo 24' walk around and even more on the 25'. They are awsome. Gives 2 extra feet of room inside the boat were the engine well is at. My buddy took some measurments off of mine and built one for his 21' key west. He built an aluminum wall to cover up the cut out in the transom and ran the controls and steering out of the back of the boat with one of those plastic boots. Picked up 5mph on the topend and. Boat planes faster and rides better. Check out Stainless Marine and Armstrong. They make them to fit different boats. Shoot me an e-mail and maybe I can answer any questions you have or send you some pictures.

Thanks a million Backwater , you got me pointed in the right direction. I see Armstrong brackets have bouyency so it dosen't mess with the balance (Attitude) of the boat.Now to see how to U.P.S. the thing...

Check on Ebay for transom brackets or gill brackets. Usually plenty of them listed on there.
