well, went out testing this morning & water was pretty smooth, 34p labbed bravo one & turned 58-5900 @ 110mph on GPS. still porpoised @ 90-100, tried trimming down and it got worse so re-ran it and trimmed so a 5-10ft rooster tail & seemed better but was riding on the very rear & felt a little loose.

I would try a 32P, but with that said..I always get really bad porpoise with flat water...throw a little chop in there and she was on top of the world..Put that 32 on there and you will run 115 all day..and may even see a 125 in some chop..OH!! and even running a BMAX on mine with dual steering and hydraulic to the helm..she was scary loose..your right..at that speed, your riding on he tail!..Have fun!!

what drive ratio are you running ? Mine is 1.5 & my engine was built for 54-5800. Being at 58-5900 now the 32p will deff bounce the limiter, thinking on going to 1.35

It's a BMAX upper with an IMCO lower running 1.30. Check out http://www.bravoshop.net/
The motor was built to handle 1200Hp but underdriven to @ 900hp. Rev-limiter set to 6200, but with that labbed 30 I maxed out @ 6000 at 115mph

Deep,
Nice boat.
I've got a 94 28 SXT with twin 502s and am thinking about fixed tabs. Can you tell me where you got yours?
Thanks,
Rick
