blue printing will take the cupping and the pockets out of the surface of the hull. it keeps it smooth and consistant.

you may want to consider looking into an extension box along with a drive that can handle some horsepower. i would think you will need upwards of 850hp to hit the 90mph range. your not going to push that thru a bravo...just throwin out my opinion but i could be off.

What caused it to blow? And what set up did you have? Im running a stock 502mag MPI with CMIs and a M-1 SC Procharger. what kinda speeds can i expect?

Mine was a 502 on about 4 pounds boost , it was close to 80. It blew from running wide open across the hole lake on stock parts , it might have been just to much. I know at about 75 you will want hydraulic steering

i have a m1. 3.5lb boost on a 496. 75 mph. 28 pitch bravo with 1 inch spacer. you may also want to consider a sea strainer if you spend much time on shallow lakes or beach the boat. does not take much to clog up the intercooler. my intercooler dumps over the top of my drive also to double up on the drive shower.
