I am in restoring a 1968 silverline belaire. I am about ready to repower and have a few questions. It has a max h.p. rating of 120hp. How do the h.p. rating back then and now compare. Also, how do they compare with the weights. For example, does a 100hp from 1968 weigh more or less than a modern 100hp 2 stroke. I was thinking about a 115 yamaha four stroke, how much heavier are the four strokes. I don't want to overload the transome.

Any recomendations on power for this boat, it is 16' and weighs around 1000lbs.
