SB: My $.02 is if you are going to keep the boat for any length of time, buy anything but a Force. Force's were notoriously unreliable and generally poorly engineered. I would think that you could put a 115 OMC on the back of your rig without any problems. I am not sure exactly what will need to be changed over, but probably shift cable, throttle cable, for sure, and perhaps tach, and steering cables. Good Luck! http://free.***boat.net/ubb/cool.gif
