motor speed control

[polarcrafter]

Has anyone used a "PWM" speed control unit to change a 5 speed trollmotor to a variable speed. Is the "PWM" unit simllar to the digital maximizer on variable speed M/K motors. If so: pros and cons!!!!!

There are a few videos on YouTube of PWM trolling motor conventions.

You can use the minn kota power drive module to do this if u can find one cheap enough. It is waterproof and works, but u gotta build a box to put the stuff in and heat sink the module. You have to buy a 1K linear taper waterproof potentiometer and a foot switch to turn off/on. I wouldn't use the existing TM foot pedal switch, but u could.

Thanks for the replys, Would the motor (windings,ect.) be the same for both a factory 5 speed and a variable speed? Parts list indicates for a 5 speed ( 12v 3.25 5sp) and a variable (12v 3.25 variable speed) The motors I have only have two wires (b & r) going down the shaft so it would seem that all speed control is done in the steering head????

Yes - the motors are the same. If you build a PWM unit you would leave the motor in the highest speed and control the speed with the external unit.
