I have a 20 175 Pro xs I just bought. Only has 7 hours on it. During break In I had a non critical alarm. Found out I had some water in my fuel. Dealer flushed fuel out of motor. I pumped my tanks empty and found 0 water. Put gas back in and took her out. Now it has a bad rough idle and actually is dying on me. In neutral, idle is fine but as soon as I put her clutch ahead it has a rough idle for about 3 seconds and then smooth idle for around 3 seconds. It seems like its starving for fuel possibly. Maybe fouled spark plugs? Any thought?
