    i posted about adding an outboard motor to my double ender....my new question is....would a inboard be a better design with just a prop on a shaft setup be better with a big tiller for stearing

    How about posting some decent information, a photo, some sizes, weights, measurements?

    That is much better.
    An outboard would be awkward, I agree. That centre partition would make an inboard "outboard hole" awkward structurally.

    Yeah, I think a small motor, pref diesel, and run the prop out to one side, so you don't foul the rudder. For low speeds, the offset shaft would be no real problem, and if the fuel and steering is on the other side, not a balance problem.
