1999 38 Scarab AVS
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.
