Today my motor felt like it had a slight miss once I reached about 4500 rpm. It is not bad but, I can tell something isn’t right. Motor has new plugs and fuel filter. Feels like it has all the hole shot but the top end dropped 5-6 mph between fishing spots. One other thing I noticed is I can hold the throttle and keep it at exact gallons per hour below 13.5 gph and it doesn’t vary But once I get above 14gph/4500 rpm, which when I can feel the miss most, I cannot keep the gph steady. It’s goes up and down randomly about a gallon. I’m pretty sure I was able to keep it steady before this.
208 hrs
could I have a bad new filter?
plugs seem unlikely because it’s perfect while idling and up to that 4500 mark
One of the fuel pumps maybe?
