I noticed this recently that my starboard engine does not produce as much power as the port. It also runs rough at about 2,500 rpm, like its missing, then smooths out when full throttle is applied but is almost 1,500 rpm less than port. I just changed the fuel water separator. The spark arrestors seems clean.
If it was prop, i would think vibration would be at all speeds. If it was a loose lead, i would have engine roughness at all rpm's. Right? Any other thoughts?
