So I'm kicking around the idea of adding a new 750cfm carb, intake and ignition system on my 21' open bow Ultimate. Aside from knowing its heavy and definately not a performance hull; I'd like to know if anything will be gained by doing those add on's. I won't be cutting down the impeller or adding an inducer. I'm sure someone here has done it and like to know if it gained a few MPH. Aside from breathing better and better response, anything else to gain? Its either buying the carb and adding a few extra speakers. Thanks in advance.
