    the kit calls for twin screw and i think it'll be awfully hard to confert it to single.

    Well I have seen a Dumas boat running two props with one motor. The motor had a sprocket that drove a mini "bicycle" chain that ran the opposing props. I cant remember if he built it himself or it was a kit but I know it was an older model and the motors were 12V.


    The best I can do with a Word Editor on how the arrangement looked. The "." Are just holding space to keep the pic correct
    The "+" Are the props
    The "-" are the prop shafts
    The "|" are the sprockets and chain
