Maybe try a cavitation plate like Max Machine’s or ????

there's one on it.

Wow, I hope you get it sorted out. I'm finding these hulls are finicky. I put a max machine worx cavitation plate on mine to help with the Sonic porpoise. Didn't do much. So after I blew my upper, I took it off and sold it. Now running a stock low hr bravo. Just have to use tabs and tuck the drive. The boat when running for speed does not like the drive all the way trimmed like most v boats. It will still hop at speed when trimmed too high. I'm thinking it has to do with the notched transom. That's why a shoorty doesn't work. Plus the hull has a pretty pronounced rocker built in. I really notice it when my boat is on the forklift. So now I'm back to wondering if longer tabs would be better. I have the Bennett 12x12 performance on it.

i agree, these boats don't like alot of positive trim. it's all by feel. when i'm trimming mine out, as soon as it starts to veer to the right, just tap the trim down and that's the spot. the only time i really use my tabs is getting on plane. i was going to buy a spacer but i think i'm going to wait, maybe someone will want to trade my shorty for a std length 1.36 ratio. i haven't gone flat out with it yet. i've had it up to 75 at 4200 rpms with alot of throttle left, like i still ain't into the 4 barrels yet. red line is 6000 rpms, but with the 34 pitch i think it's going to run more than that.
