I have a 1985 Critchfield Marine 17 foot Center Console. there is a sticker on it that says "USCG Maximum Rating 115HP". it currently has a 75hp Chrysler installed, but i am considering installing a 120hp Force. Does anyone know what the difference in weight between a 115 and a 120 is, also the 75hp Chrysler looks bigger and heavier than the force, is it? What will or can happen if i exceed the rating by 5hp? also does anyone know if the controls for the 75hp Chrysler will work on the 120hp Force? Thanks
