Berto Aussems of Maastricht, the Netherlands, built a trolling motor powered by a drill.

Anyone with a cordless drill can make this trolling motor, just from wood. This is a fun project; making it, in a couple of hours, and to navigate on still waters. OK, you have to buy a propellor, a square drillhead, a strip aluminium, a trottle handle, a threated rod, screws and a plank of impregnated wood. This video speaks for itself; all is visible. The project is Open-Source Hardware. Now, make one for yourself and one for your best friend. Enjoy!

    1. Especially since that looks to be a harbor freight style drill (or whatever it’s sold as in the netherlands), and those usually are rated optimistically at 1300mah. The right-angle chuck looks to be from the same supplier too since HF sells one that looks identical, so it’d be a good idea to open it up and pack it full of grease to help it survive submerged better. Not sure how a drill’s motor will do with continuous use like that since it’s not really a huge load, but they’re not normally designed for continuous use either…. Still a cool project and if you were just sneaking around a  little in the pond it’s probably practical.

      1. I have to admit, this is a cheap style 12 V drill, but still usable for this purpose. The battery is an other story. Expensive cordless drills have much better battery’s, no doubt. They have also a  switch for the gearbox with low/high speed. Great for getting the right thrust on the prop. To expand the range I made an adaptor plug on the battery. Now I can use an external battery of 12V and 12Ah. See: http://www.youtube.com/watch?v=OuDDXnU4uA0  from 2.30 min. on. The right-angle chuck I was filling up with grease for a smoother drive and it keeps the water out. Good to mention that after a 20 minute continuous use the drill was warm, not hot. Look to the holes I made in the plank for ventilation! Thank’s for your remarks and appreciation. 

        1. Very cool. I rebuild drill packs at work all the time and I’ve seen that particular pack built anywhere from 12v to 18v. I agree that 12v is most practical since it’s easy to hook up to a larger battery and it’s nice to hear that the motor even on a modest drill doesn’t get too hot.

  1. This is close to being the most ridiculous “green” thing I’ve ever seen!  Powering a canoe with batteries just so you can travel at about a quarter of the speed a single stroke of a good paddle would get you.

    1. I’m a 83 y old w/heart problems,after rowing a little got exausted this troller doesnt waigth to much,(no heavy 12 v battery to carry) can xchange spear battery if needed in secs.I can enjoy now being in the water in my rafter. Now, tell me if is ridiculous
      ?

  2. Neat little project.  Is there a way to make it quieter?  I don’t think I would be able to sneak up on any fish.

    1. Pack the drill’s gearbox with some better grease and remove any unnecessary drive gears. A drill motor’s not probably going to get too much quieter even with that though.
