Looking for some one who has owned or used comparable engines to tell me just how much more I can expect out of upgrading to a 115 from a T50? Obviously it is more than twice the horsepower but I'm trying to take into count every aspect to justify the extra cost. I could pull a tube currently but looking to possibly be able to pull a wake board and or ski's also. I have only owned the T50 and really have little experience with anything bigger so any idea to help me paint the justification picture is appreciated.
