    Sounds like you need to talk to the builder.
    Contact CustomGheenoe and find out what they recommend.
    They've probably had every combination of prop, motor and gheenoe
    go through the shop at one time or another.

    Honest answer, I would have to do test rides with a tach and gps
    until I found best speed/rpm/jackplate height combination.
