Not saying it is impossible(well, actually I am), but 65 is only 2% slip, 68MPh would negative -3% which IS impossible, so was that 68MPH measured on GPS or not, we need the whole story in order to help, and the ACTUAL RPM while running that speed in order to calculate what is best for you.

ok ill get a better reading this weekend so dont start a he said she said match.. but it was on gps and i could be wrong..i the boat is new to me and i was riding with the seller with the gps, so i will do it at the lake this weekend.....and maybe a video, then u can tell me what u think would work.

thanks..

just looked to make sure.. the boat has a bravo 1 out drive with a mirage plus 21p prop. just more info.. does anyone know how much hp that outdrive will handle?

thanks

OK, just making sure all is actual, not presumed. The Bravo drive will handle anything a small block can throw at it, especially in a small boat like yours.

would it be hard to put twin turbos on the 350 and forged it..or would i be better off going more cubes?

or i do have a new 6.2 ls3 motor..would it be hard to put that on the boat or would i have to change the computer on the boat? sorry fot all the ?

I believe both of those options would be too much work for that boat, but to each his own. I believe the mag motor may be forged already, but twin turbo's is a lot of $$ unless you are up for it, not sure what it would take to use the 6.2. There are other options also, such as build up the 350, maybe a supercharger.

i got ya...thougt about taking that 350 block and making it a 383... is the 350 mpi the same has a car motor? like heads and intake and such..cam upgrades?? i have not had anyone that can give me a str8 answer...lol

thanks

You stated in your post earlier that you were gonna buy a bigger boat next year. Your best bet (money and problem wise) is to leave that boat alone. It sounds like it runs great now, so just enjoy it the way it is. You'll end up putting alot of money into it, breaking parts, and possibly being down for the season. Your trying to put a 900HP motor in a Chevette. Boats like that can only handle a certain amount of power, then they start chine walking at speeds, cause more trouble than they are worth, and if you have a family, they wont enjoy it. Get a larger boat that is more capable of handling what your trying to accomplish. Until then...leave this fun, family oriented boat alone...lol.

Sage advice. I've seen many, many people - in search of speed - get downright silly with motor mods. The they find out the outdrive won't handle the power. Next, they upgrade the outdrive - only to find out the hull just wasn't cut out for it. Finally, they find out that their boat was worth twice as much stock as it is now with thousands of dollars in mods that nobody (with any sense) is willing to pay for. Don't join that club. People have literally died doing it.
