Prop slip help essex valor 24
 

I have an Essex valor 24 with a supercharged 496 ho. I am running a 29 p bravo 1 prop labbed. It is fine out of the hole and fine after 50 mph but I literally can not trim the drive at all below 50 mph. If I do, it slips like crazy. Once I get rolling past 50 I can trim and get good performance. I took the prop in and they added some additional cupping and it made no difference. I run 79 mph at 5100 rpm topped out. Any thoughts on how to make it more usable under 50 mph but not lose the top end?

I experienced the same problem and went from a 14 diameter to 15.25 and it fixed it for me. I had to go down in pitch to make up for the diameter.
