I have a 1980 model 9.9 and am haveing trouble geting the right shifter adj. ,I can get at the shifter linkage, Does the bottom end have to be right off?
My motor under load 3/4 or more rpm slips out of forword gear and the bottom end has just been rebuilt. Also what other parts need to be replaced other then the carb to increase the HP to 15HP ?
