I have a 2009 Yamaha 9.9 hp 2 stroke. Yamaha offers a 15 hp also what is the difference parts wise to make mine 15hp . I have checked the online parts fiche & don't see any diiference in part numbers on carb,intake,piston,CDI box,head or gasket. Just wanting a little more out of it. I did the samething with my 88 Evinrude 25 hp making it a 35 hp with a simple carb change but I can't find the difference in this Yammy 9.9 vs 15 .
Anyone have an idea?
