best solution are a pair of long k-planes and a propeller with a lot a cup in it.
Hydromotive used to make the Turbo..maybe they still do?

i think i have talked to you before sir, but i thought yours as a LH prop. i could be wrong though. brett at bblades says he can re-work the B1 to be all i want it to be. i just need to get some hard numbers from a mirage plus 23 or 25.

I have the same issue with mine. Got it a little better but not much. Any ideas other than the obvious of getting another boat?? Which is not an option. Boat info: '91 Baja 290 Sport, 38" draft, 21 degree deadrise @ transom, 9 foot beam, weight 7,000 lbs. Twin 454, dynoed @ 460 hp each.
Had bravo 1 marage plus on it before. Bennett trim tabs, boat would only accept 3-4 seconds of outdrive trim before startint to bounce. (less than a quarter trim). Tried everything on different tab settings, weight and speed with little or no difference. Sold props and Bennett system.
Swapped to PowerTech 23P 4 blade props, added offshore performance series tabs from Lenco, 20" long. Removed some weight from bow area (junk). Boat has a holeshot from hell now at 3/4 throttle. Faster through the midrange RPM but lost 2-3 mph on the top side. Not an issue to me. Tabs helped.
Still have the bounce. Helped but no where as it should be. Again tried different combinations of speed, drives out/in, tabs etc. Found that the best I can do is tabs down just below horizontal, drives up 3-4 seconds (still less than a quarter up).
When I cross any fairly big wake I trim drives down completly then cross wake. I have read that to go faster or slower to get through the bounce "zone" but seems like this boat has no zone. I have a buddy that has the identical boat and his acts the same. Boat has alot of room and such, just rides like crap.
Looking for ideas. Have thought about putting more cup on the props next. Help.

Have you checked your propshaft centerline? Most Baja's are really deep mine is at 8". That is why a lot of guys are putting imco shortys on. I have tried several props on mine and a Mirage plus seems to work the best.
