    Will a jet drive from an 93 johnson 115 bolt up to a 77 evinrude 140 model # 140743S. I think the clutch dog is out have replaced the cables and adjusted per the repair manual. Works fine after you run it for a while, but if you sit for a while I have problems with forward and reverse.

    I think the jet will bolt up but not sure about the upper shaft splines.

    Upper shaft splines are different. Those 77 and 78 were two years in a world all to them selves.
