    Outboard length

    Will a 20" Johnson outboard work for a Donzi F 23 transom? I know how to measure to prop, but has anyone run a pair of short shaft 20" motors? Any issues?
    Thanks.......all ideas appreciated!

    Don't be discouraged if your answers are not plentiful. The vast majority of people on this site run I/Os, not outboards. Also, not too many with that boat.

    Sounds to me like that would be a 25 for sure. A 20 is a very
    short shaft length. My maritime skiff uses a 20. It has 12 degree
    dedrise hull. Almost flat. I would think the F23 has a much
    sharper V hull than that

    25" is needed

    I did some measuring and 25" is necessary. 20" would be too short, even in a dual setup. Thanks for the replys!
