9.9hp to 15hp

[g7evans]

I have a 1995 9.9hp Yamaha. Ive heard that the only difference between the 9.9 and the 15 is the carburetor. does anyone know if this is true? if so....is there a real difference in performace on the water? any advise would be appreciated

Reed Valves and carbs.

You could take your carb apart and replace all the little parts: jets, nozzels etc.

If you are going to a 9.9 lake you can hear the difference in motors all the way across the lake. At least I can.
