Turn Any Trolling Motor Into An Infinite Variable Speed Control For Under $20

Amazon has changed which PWM the link goes to, so I've updated to a different unit. If you see a product that isn't 25 kHZ and rated for at least 40 Amps, then look for a different one.

    This makes my old motor look like a toy enjoyable.fishing recommend it's well built. I haven't had it on the water yet, but I'm very sure it will perform just fine.
  • @rodbrown8306
    Very clever and kudos to you, didn't realize these motors are continually drawing full amps even on 1-4 settings on the 34lb motor as well.
  • @pmclellan123
    What a great video. Thanks so much for explaining all of this in such great detail. I really appreciate it
  • @luz3888
    This is the first trolling motor I have owned. It’s been great! Lots of thrust. Would recommend.
  • GREAT VIDEO! Working on this conversion now on my Hobie PA12. I would have never thought about putting the Infinite Variable Speed controller inline with the battery pack had it note been for this video. The explanation of how and why it's better is perfect! Thank you sir!

    Works great. Prop spins at half speed directly from my 100 watt solar panel. It’s best to wire around the cheap switch in the head. Take it apart, contacts are like tinfoil. Solved my overheating problem with lipo batteries which run 13v and don’t draw down under load. One note. The description says the three position switch is forward reverse and brake. If that’s true then the middle position will draw current unless the speed control switch is turned off.
  • Using this method could mean you'd be able to get by with a smaller battery, saving weight and $$. Awesome stuff!!!

    Enjoyed the diy video. I have an old Minn Kota Model 35 from 1995. The switch burnt up and I had an interesting leaving a smoke trail on that outing. I’m not a good swimmer but the kayak isn’t either with 60-65 lbs of excess weight mounted on it. When I bailed out with my life jacket the tipped kayak filled with water and sank to the bottom.
  • Your battery was at 82%. At the start it actually showed 75%, as you probably know by now the meter was upside-down 😂 Apparently those watersnake motors are not like other motors and are very efficient on the low setting. It's probably PWM but not variable but don't quote me on that lol. The 24lb thrust motor uses 20Ah on High and 9Ah on low. The 18lb motor is something like 15Ah on High and 7Ah on low. Saying that variable speed and also having the controls up front is nice 👍

    Hi Dan, Great video and it gave me inspiration to use it on my kayak. Just had the speed controller go out and found out by accident it was the on/off/on rocker switch. Very cheap switch and found them of the AZN web site 5 switches for 4 dollars. Just wanted to let people know before they throw their PWM unit away to check the switch. Yellow hot, black forward, red reverse. You can direct connect the wire to check and see if it's the switch. I can also hear a relay clicking in the unit but it's still working so I haven't tried to access that one yet. Hope this helps someone.

    I built a PWM trolling motor controller that would run off an old Nintendo NES controller, up/down did speed intervals, left/right did steering and A/B did forward reverse. Unfortunately, it was in an audible frequency range since I didn't realize the switching frequency was so important.
  • @robertng9330
    very well explained description of the working of the PWM. thanks!
  • hi Dan why is it that no body is willing to share and show how they hooked up the pwm controller but you do just that thank you for that you have explaned it very well the best ive ever seen mate thank you so much
  • @Jester123ish
    EBay sell a waterproof PWM type DC controller that seems to be the right spec, max amps is lower at 20amps, and you’d have to wire your own reversing switch to the outputs.
  • @andthesunsets
    I have a Minn Kota c2 40. Its a 5 speed and it does not do full 40a draw at F1. F1 draws only 6.6A and F2 is 8.3A. I believe there is inefficiency at low speed but highly exaggerated
  • Very impressed with this solution for infinite variable speed but too many negative comments on Amazon regarding the quality of this controller. One customer put the unit on a scope and it was not 25khz but 15. Some found it dead on arrival others found it burnt out quickly. I was wondering if anyone has found a better product?
  • In the instructions of the watetsnake tho you can find different amps draw according to the speed used It I dont recall wrong
  • @mozzrich
    Nice Mod - A few Anderson plugs would tidy up your wiring
