Can't be that simple

I have been told that the only difference between a 100hp 89merc and a 115hp 89 merc is the carbs. Is that really true?

Well you have to look at all the parts and numbers.-------It could very well be true.-----Same as the 3 cylinder version of this design one is 75 HP and another is 90 HP.---------Mare air / fuel going in means more power coming out !
