Changing a fixed speed trolling motor to a variable speed?
Has any done a conversion on a fixed speed foot controlled trolling motor to a variable speed unit? There has to be something on the market that could be used as a rheostat switch to give myself better speed control. Any ideas, or advice? Thanks in advance! Rollcaster.................

MK used to make an external device that performed the pulse modulating function that is now integrated into digital motors. It was called the Maxximizer.

I started to buy one of these units. I was told it would only work on a 12vt system. My TM was a 24vt. You can usually find them for arond $100 on ebay.

A co. called Vexilar made one of these too, but I forget what exactly
they called it.
Didn't Canepole put up some diagrams of how to build one yourself awhile
back?

Look for pulse width modulation (PWM). That is how you get variable speed on a DC motor. You want a model that can handle 40-50 amps. Cane Pole posted a circuit diagram about a year ago that you can build.

if you have a 3 speed trolling motor go to advance auto and get the resistor that goes on the fire wall of a ford it use ta be alittle 1/2in square about 2ins. long and now its a little round thing and put it in the circurt and get a 50amp. switch and bridge it so you can flip the switch and go back to what you had...might help I took a 3 speed and made a 6 speed out of it and if you got a 5 speed you can make a 10 speed out of it...
People may not remember exactly what you did or what you said,
but they will always remember how you made them feel

Motor speed control out of Wal Mart electric shopping scooter works fine.
I have a circuit you can build if you can build electronic circuits. Parts bout $20.00. 40A-50A max...Simple pwm. Mine works fine. Several people built them. Ain't nobody shot me yet cause it didn't work. I ain't heard any complaints. Not for the unskilled or lame. It is rfi intense (pwm) and not for the pacemaker people. The circuit is hiding somewhere on my computer.
Anyone is welcome to use it. I am not responsible for your wiring, etc.

This is a PCDN circuit. Not efficient, But will work.
