ok 240sport baja 88 has a wind fairing like the outlaws
. my height was 5 1/2 with add on steering had to drive with the chinewalk by sawing your arm back and forth so the hull was even and my arm was moving very fast. my boat with about 670hp went 83.2 gps ran out of prop I needed a 28 b1. boats for sale but needs work it has a light weight scoop in the back its a pro stock one. anyway with the light hatch and was making a new back seat my boat was under 4000lbs. 24degree small pad over 70 my chines were out and my tabs were light have 280s k from merc. theres a 250 ol the guy had a 525 merc with a 3'' raised imco box12'' set back it ran 81.3gps with a b128 he moved up to a 600merc and a 2'' shortie but added a 1'' spacer to set a height of 3 to 3 1/2'' its been a over a year since we talked

I have a powequest 185 xlt, 428 sbc. I am at 6.5" with my alpha SS. Right now its runs 87-88 before I get blowout, Switched to a bravo1 prop and its alot better. Planning on raising my X dimension 2.5-3" here pretty soon, That will put me about 3.5-4" below the hull.

38 scarab avs 4" drive hieght
-2" imco's
bravo 1's late model after '02
bravo 30pitch 4 blade supposely labbed.
just got the boat 2 weeks ago. been out only once with previous owner. Saw 80 mph 5000rpm flat lake water.still was climbing.
previous owner says 83 to 85...5150 rpm. but...... boat is hard to plain. Do you guys with the higher drive hieghts (38 footers) have to use alot of tab to get on plain? what are my options to get out of the hole a little better and not loose to much top end?

I am not familiar with your setup. But from what I have read, most would try a small spacer or a 5 blade prop. I will be trying new props myself after I raise mine from 8" to 5".

Lowering the drive shaft height or adding blades will likely scrub speed but either will make it easier to get on plane. I believe that a 38' boat w/5-blade props will also significantly increase the chance of Bravo Drive failure due to reduced prop slip. Using your tabs and breaking the props loose is a sign to me that you set up is close With 5-blades, you might see + 1-2 MPH...is it worth the extra drive stress?
Consider trying a set of B1 28P. They should make it easier to get on plane and you may pick up a few more HP with improved acceleration.
