Electric Boat Motor Basics

    Electric motors are available in a variety of voltages in both AC (alternating current) and DC (direct current). Their amp draw is based on the available voltage and the horsepower of the motor. Electrical definition of one horsepower (1HP) is equal to 746 watts of electrical power. From the basic formula of Watts = Volts x Amps, we can see volts and amps are inversely related. For the...
