2014 Mercury 40 hp CT
Hi there, I bought my engine last year with very low hours. Ran well and then this year it is running very rough, almost like coughing when first engaged in forward. After I give it some gas, it has slight hesitation and then runs beautiful until I pull back the throttle almost to a idle. In neutral it seem's fine. I have changed the plugs ( with proper gapping), and the fuel filter. Amy thought please? Dirty injectors? I originally thought I had some bad gas?
Thanks for any suggestions.
