I`m planning on buying a new 25 Merc 4 stroke (weight179lbs) on Tues. for my 13 footer. Previous power was a `58 35 Evinrude Lark(weight125lbs) 29mph gps with two people. The new Merc may a couple mph slower. The old Evinrude was shaft, not prop hp. Thirty years ago I had a 13 footer powered by a 25 Evinrude (shaft hp), that would pull my daughter on skies.
Transom weight is the biggest problem with the 13 ft. Whaler. they run well with a 25, and the extra weight and the 10 mph speed difference in the 40hp, causes porpoising problems.
Personally I never have more than one person and myself aboard.
