awesome build! as a former seadoo tech I can appreciate your skill and hard work putting this together. I have dreamt of it myself.
i would hook up some sort of trim to the nozzle that way you can angle the venturi down and get rid of any top end bounce....

We have electronic trim tabs on the back end of some of the air boats that tend to porpoise at higher speeds. Obviously the big rock(weight distribution) is cheaper. Awesome skills.

I don't know if they make a thrust adjuster for that pump but if there is one available it would eliminate the porpoising. Trim tabs might work too. Add a nozzle restrictor for more speed if the HP is enough. Even that might gain enough speed to get above the porpoising stage.
Good job!

Always wanted to build one of these jet-jons. Only thing I see that looks off is I would have mounted the intake grate area flush with the bottom of the boat instead of below it. All that fiberglass will be the first thing to hit the bottom if you do....

Most I've seen are built that way for shallow water capability. Some even built into a shallow tunnel almost. Most seem to be running pods on the back as well. That might help with the cavitation issue....

Here's a thread I found last year from back in 2012 where someone cataloged their DIY jet-john build. You may find this interesting or helpful, I sure did.
