I just tried a un touched 30 bravo. At 3800 61-62 and at 5200 85.8 so i'm sayin 86.That was in dead calm water. The boat likes chopp. I think a 30 labbed might be the one.I only have to trim it a little and it throws a mean tail.Chris i think you might be right with the px5 what pitch do you think i would need.
Thanks Rob

Chris you think a labbed 29 won"t be to big.Are you selling that prop?I really would like to try one.Do you think i will lose some speed up top or gain with a five blade.

If it gains quite a bit of rpm, throws a rooster and does not pick up much speed, then I would say you need to go an inch deeper with a spacer. A 5 Blade may also be the answer. I had the same thing on my 28 Pantera. I dropped an inch lower to about 4.5" below the bottom and the boat responded much better to trim. Slip went down about 5%. Picked up 2 mph on teh top end. The 5 blades were not out yet when I did this though and I never tried one.

Well the 28 bravo that was labbed that prop for some reason the more i trimed it it got faster but real lose and felt unstable.This 30bravo one the more i trim it it just keeps getting faster and throws a huge tail.And my slip numbers are 12- 13% across the board with the 30 so that might be the prop.

The 30 Bravo 1 numbers sound real good. With 12-13% slip your slip is just fine. If you need some more rpm, then contact BBlades. He should be able to tweak it without changing any of the handling characteristics.
