Outboards don't make the big roostertails like monos do. I had one of these hulls, actually 2 of them, one was the electric version. The CG should be at about 28% forward of the transom. Set the motor up so that the center line of the prop shaft at the drive dog is slightly above the bottom of the sponsons. Tweak from there.

roster tails are nice to look at but, it is caused by the prop slipping. the flater the tail the faster you'll run.
