I HAVE A PICCO 90 NOW IM PUTTING IN A 43'' V-HULL BUT I JUST BOUGHT A 60'' CAT HULL, I WANNA RUN BIG POWER. MAYBE TWIN 90'S?? I DONT REALLY KNOW ALL THAT MUCH ABOUT NITRO MOTORS. ANY HELP WILL BE GREAT!!!! ALSO NEEDS TO BE WATER COOLED.

First let me say the 2 90s would be 2 times the weight, 2 times more trouble getting them to run properly together, 2 times the drive setup thus more weight, 2 tuned pipes, etc.
Go get yourself a CMB 1.0 new this year, have Rod Geraghty modify it for more power if you think you need that, and run the boat that way. I doubt that a 60inch boat will EVER run with the smaller ones, there simply is not a motor that will do that. The CMB 1.0 will possibly get you say 60mph or so and that is a butt load with such a large hull!!!!

Now that's a pretty crazy engine... Must sound pretty mean!

thanks for the tips, ill look into that, I was even thinking of a 80 cc dirt bike motor, but i gotta get rid of the transmission. I have a year to buikld this boat to try and win a bet. I have a friend that is building apache boats. He is building a 41' apache with twin 1000's with number 6 drives, our bet is i can run beside him at 60 for 10 mins. so I need big power and lots of fuel. So I was thinking of running full staggered 90's. how can i get one of the motors to turn in reverse? What do yall recomend, props spinning in or out i know in big boats, in is faster out is more control. Also how do I rig for twin motors two servos, one for each motor? or is there a splitter or something?
