Re: water under floor
Super.
Did you go to the old omc site and get some ideas about performance. While there, note where the anti-vent is located with respect to the hull. All I saw were an inch or so BELOW the bottom; You could see that when they were on a trailer and if you payed attention to some of the "underway" shots from behind the boat you couldn't see any of the plates except for the '77 200 hp hot dog .
One thing to note is the size of the droplets in the spray coming off the boats. The larger the droplets, the slower the speed at which they are made, and buddy there are some big ones, especially in their shots of their "Ski Twin" 33 hp......and note the skiiers are women.....99 lbs soaking wet d

and most on 2 skiis.
