    50 HP Mercury runs rough

    2002 50 HP Mercury rough idle

    I have a 2002 50 HP Mercury which idles rough but <br />seems to run smooth above 2200 or so RPM's. I have replaced the spark plugs with no effect, and don't suspect spark plug wires or it would act up at higher RPM's. It has no throttle hesitation. Can anyone help me? Thanks.
