Minn Kota PWM conversion

[RonPaulFan]

Pulse Width Modulation will greatly increase the energy efficiency for use at less than full power, so you will get a longer duration of propulsion out of the charge on your battery instead of producing waste heat or you can get by with a smaller battery for less weight. It accomplishes this by rapidly pulsing full power instead of using resistance. If you mostly just use full power, then it won't change efficency.
