Re: Optimal propulsion system

OK..This sounds like something I've been daydreaming about. I have a 15 Kw/55 amp propane 4 cyl Onan gen set. Total weigh w/o gas is #850. There is no out shaft, as the gen and motor are interconnected. I'd like ta see what it would take, motorwise??? .75 X 15 formula comes up to 11.25 hp. Size a boat to that hp and see if it could handle the weight of motor and gen set as ballast????? Figger mebbe 1200# with a couple batts and motor controller. If ya could mount the weight low enuff...........
