out drive and prop advise
I have a 29 fever with a 575 @ 750 hp, bought a 2 inch IMCO shorty and put it on my XR upper, tried 2 different props my original bravo 1 30 and a herring 5 blade lab finish 29 in both cases slip numbers are off the chart. Has anyone had similar issues like this? Should I put spacers on the the lower unit? What would be the best prop? Top speed so far was 83

My 27 had pretty high slip compared to a surface prop. I ran pretty good with a labbed 28 bravo and i could pull a skier behind it too ( it had a blower). The hydromotive 4 blade cavatated a little . Find out you x dimention, call BBlades . ( they will let you try props for 25 bucks for a week . Otherwise you are not going to get the best numbers off of what someone says on here imo. The p5x was pretty good on my 38 until i raised the x dimention.

I'm running a 29 with -1" IMCO shorty... Pushing about 640HP. My best is 82 running a 28 labbed Merc Maximus 5 blade. But, I have slung blades on 2 of them. It's getting expensive. My experience has been this: A labbed 30 Merc Bravo 4 blade likes weight. Best speed is with full tank and 5 people. The 5 blade likes it lighter. I have also tried the P5X... But, is was a 30. I think it was just a little to big. I liked the way it ran. It was not labbed. May try a 29 P5X next.
