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?
