Silent, i disagree with Phontom. look at my sig my 97 312 runs great all the way to mid to upper 90's gets a little loose over 100 (runs 102 gps light load) great boat responds well to the imco -2 shorties. Get the right person to tune the motors. also my boat had 1:65 gears from the factory ended up with 1:36 turning 32 pitch bravos. Have fun good luck

IT's killining me to either do or not.. been up for weeks in the am..is that sick or what? I found an installer that does it right but its about 13 grand + pro chargers.. heads worked, new fuel systems, Mefi 4b's and harness, re work of injectors etc.etc. but I guess theres a wrong way and a way to make it live.. at my current 73mph my boat is begging for more.. I feel it wanting to go but it can't. I do have Hyd steering and K-planes. Bravo-1 drives. I'm running 30p labbed Bravo-1 props.. thought is I will need to jump to at least 34's or more.. have to test I guess.. My current hole shot is great..
I guess I need to loose some more sleep and think about it..:eek:
