Bennett makes the units used by Supra, Centurion, Mastercraft. Their website has installation instructions on it. Overtons www.overtons.com
has several sizes available for wakeboats. You would match the profile of your manual plate. I've had 3 boats (1 Moomba, 2 Centurions) with wakeplates. I would not order a boat without one. Great for eliminating porposing and shaping the wake. I haven't installed one but I would not be afraid to tackle the job.
