i cant find any info on how it may help so im going to avoid it, im leaning towards the drive height, figure itll be the same trimming up the drive and with it being shorter it may help

Whats the beam on your boat? I had a bunch of hp in a Baja 272. It was pretty flat with labbed 28/30s and 32's, it had a little tq lean when I ran non labbed 4 blades, tried a couple 5 blades and boat would roll over under hard throttle to where rub rail was in water.. 7.5" prop depth. Prob with dragging the tabs like mentioned and Im sure you already know this is the minute you back off the throttle boat does evil **** in opposite direction. A friend had a 24 sunsation, he always had to drag a tab (narrower beam) above 65, when he tried to run 4 blades boat torque leaned sideways. With 800 hp I dont see you having ANY chance of running a 3 blade, Smitty

98" according to the builders website
i only tried dragging the tab once, besides the total lack of speed it was not fun on the off throttle haha
i was wondering how a clever style acts in difference to a normal bravo prop. not worried about getting on plane if thats the big trade off

i had a 1986 nova spyder , with twin 330hps, boat rolled hard to STBD side, i would correct by trimming drives. LTZ your trim tabs wont offset the roll or pull??
my machine shop owner years ago , ran a 25 checkmate with a 468 . boat ran mid 70s. i ask him about the roll or pull from torques, he said he ran a LH drive.

no pull, just the lean.
trimming works up to about 70, past that i dont play with the trim, ran it at 75mph and played with it, started to porpoises before it would level out so i gave up.
tab can take it out but it scrubs so much speed i might as well just run slower haha.
tried a left hand, just tilts the other way with the same issue
