"I have just purchased a 2004
"I have just purchased a 2004 yamaha 9.9 hp four stroke for my jon boat, it just isnt enough power to get it to plan completly i have heard it is possible to do the conversion with a carb change, reeds, and exhaust. Guess i just want to know if it is possible on a 2004 four stroke? Any help would be greatly appreciated. Thanks"
