    20 Pro xs question?

    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?

    Put this in the appropriate Mercury forum and be sure to include serial number. Some very sharp Mercury people over there.
