I run a stock Intruder on a 93 Ranger 482VS with a 13.5 x 23 Renegade - no jackplate. The boat runs mid 50's, 57.8 gps best ever, and the engine has been extremely reliable. I would like to have more HP though and am trying to learn what aftermarket improvements could be done to get me closer to the power generated by a new 150 / 175 without sacrificing reliability?
