Well....dad has a 93' Fever with a Bravo 1 Drive. He put a blower on his 502 and "said" he had gotten to 91 MPH once upon a time. Not sure on that, he has always told a tale or two, but he did say that around 80mph it would chine a little, but if you slowly power through it then it would smooth out. Not sure on prop used but he has always been high on the M+ when it comes to speed for his 27' Fever.

The 98 hull may be slightly different than the 93....not sure if they added step to the 27 or not. As far as the outdrive....my thought is that the main issue with "keeping" the bravo when upping the HP is pushing on it too hard out of the hole, once you get on plane I don't think you should have any issues with it unless you go to some huuuuuge HP. I've known several guys to put blowers/chargers on 500/502/540 and not have any issues with the bravo one..... then there are those that claim that you can't add over 600 hp to the bravo 1 or it will spontaneously combust. I pushed a bravo 1 single engine with approx 675-700 hp but took it super easy out of the hole and never had a problem.

I have a 05 29' Fever /w/ 750 N/A injected 588 ci. Bravo XR -2 Imco lower and E- box, I am currently running a 30 p 15 1/4 " Bravo LH labbed . It runs 94 on GPS .Things get pretty squirrelly at 85 and it settles down at 90+ . It can be a handful !

Don't quote me but I think they added the stephull in 95

95 step....yes
 

mine is a 95 and it is the step.....i think the x dim is lower also...he changed that later

I did mine years ago, one of the first they'd done, about 85 it was scary, needed more nads than I had to drive it. Twisted my Bravo right away, then put an IMCO shorty on it.
Fast little rocket, have fun.

Bad post sorry
