    You can use a cable and pulley system. If it doesn't have a hook-up for shift and throttle you will have to fabricate them.

    Been there, done that, got the tee shirt

    Ok i tried it already, the weedeater egine is not going to have enough power to push the water its going to bog down when you put the shaft in the water. you need something a little bigger about a five hp with a horizontal shaft. I'm from louisiana and we do this kind of thing all the time. If youre doing on a pirouge, the boats not big enough to control from the back of the boat, so a go devil or aircooled outboard is out of the question f it is a true pirouge, the best thing to do is get a small shaft machined and mont the motor inside the boat where the boat will still be balance right. the shaft should come out the back right on the bottom and sides meet in the back if this makes sense then you need to make a bracket to hold a rudder over the back of the boat almost like what you would find on a sea kayak then you just fab a control for the rudder so you can control it while sitting in the middle of the pirouge. If you do it like this with a very small prop you might be able to get away with the weed eater engine, but all of the ones that i have seen have at least a 5 hp. when i did it i was going to try to make a motor simular to a go devil but the weed eater wouldnt run when i put the prop in the water (i tested it in my swiming pool) also it would be very hard to control an motor like that is something as unstable as a pirouge. If you did want any other help with this i could answer any questions you run into. these are exactly the kind of projects i'm always working on

    Weed Eater Motor

    weedeater conversion to trolling motor

    this technology ate my typing so now you get short version. lucky you! just put a small paint stirrer on the end of a weedeater and it will work pretty decently. I figured this out using a barrel with water. if you use a big bucket of water you'll figure out more. have fun and get wet. oh yeah when you are in the boat going thru the water and thinking cool this works, don't forget to turn or stop somehow. robert.

    Weed's comment about the enough wind alone to move his 12' jon boat reminded me of a question I asked about a year ago. would a small engin put on a 3" dia fan move a 12' canoe with 250lbs in it?

    here's a quick sketch. I dont have the fancy cad /web designer programs. Just a pencil, an imagination and the willingness to try anything that'd be cool, fun or original.
