Re: [Electric Boats] Re: Speed control for electric out drives

Hi All,

I was able to disassemble the head of one of my MK 70EX drives, it has a pressure actuator that controls on and off in both rotation directions and the speed, as the pot input dial is rotated the contact is increased and thereby the speed increases. There are two, flat three wire embedded ribbons going to the actuator assembly from the control board.

The question for the group: can I use a PC Mission joystick contol to do the same thing as the pressure actuator and control both drives with out any extra components? The factory heads could then remain on the shafts and I would be able to have control from the steering console or the rear fishing deck.

Thoughts?

This boat is getting closer to being launched.

Thanks,

Ric

If the RC car controllers are of sufficient amp rating you could use them to drive the motors and bypass the MK parts. If your MK motors have PWM control - good, if not you are wasting a lot of power at anything but top speed.

My MK 36 Endura used cheapo automotive spade connectors inside which got pretty hot (more wasted power). High end RC car connectors worked much better.

I am using two Minn Kota drives, like you, and for remote control have removed the heads and replaced the twist control arm with a small 12vdc motor that I control remotely. So, inside the head is now a motor-driven potentiometer.

Its not obvious how you could simply remote that nicely designed water-proof control pot inside the Minn Kota head, so I kept it.

Then, to operate the motor-driven pots, I use a wireless controller from an RC car. Let me know if you want some pics of how its built inside.
