Yeah, we'll pretty much stick almost 1200 hp in anything that floats

The guy that had all the people in his boat has a really healthy 632. It has a big solid roller, bunch of compression, etc. It supposedly makes about 900 hp. The biggest difference is the size and weight of the boat. My customer has a 15 x 8 boat with a 3/16" bottom that weighs 3900 lbs. The other guy has a 14 x 7 that weighs 2100 lbs. Even with 10 guys, women and children, he still didn't add 1800 lbs to even out the boats. We actually hooked them up to scales to see how much thrust they make. The average boat makes 1500-1800 lbs of thrust. The guy with the 632 made 2100 lbs of thrust. My customers rig made 2800 lbs of thrust. We made a bunch more thrust, but the boat weighs 1800 lbs more.
I've learned a lot doing this project. I was told that weight means everything is these boats. Guys will give up hp for the sake of weight. We are still working on this one to try to eliminate whatever weight we can. The intercooler tank,when full, added about 150 lbs. We found that we don't need all of the water in it since the intake air temps are going over 120*, even when the ambient temp is near 100*. So, we are slowly taking water out of the tank to see exactly what we can get away with.

Them guys spend tons of cash on those boats. I've done a few, friend of mine probably did that engine in it originally.
One cool one was an all aluminum 632 with some efi.

You really can't run it wide open. Once you hit about 70 mph, it gets so stupid that you can't push it any harder. The bottom is covered in 1/2" teflon and as smooth as can be. It doesn't have any strakes or skegs to give it any directional stability. It literally wants to start going sideways at 70 mph

Eddie.
it would be mounted on the rear transom so that it does not impact the smoothness of the bottom and it would have springs in it that allow the fins to retract when they meet the resistance of land or a hard object, but the springs are just strong enough that they stay extended when met with the force/resistance of the water....incorporate the steering system with them as well so they help keep the rear end from sliding out in turns
it would be similar to a cheap old school boat speedometer mount only it would be a fin of course with the retraction feature and the steering and it would also have a retract button as well for when the operator does not want it hanging down
