[Electric Boats] Re: A little help on a motor

 

Hi Folks,
You could find a controller... but unless your going to 200 volts and use a gear box the amp rating is too low. At 48 volts, shaft rpm would be good for a large, efficient prop but at only 25-30 amps it leaves you limited in power. watt=volts X amps... 48vX30a=1440 watts, only just less than 2hp. So this is not a good choice..
