I have a 2018 Mercury 150 hp , it will run strong up to about 3000 rpm and then it starts cutting out. If I back off a little and then try to speed back up and do it slow I can get it up to 4000rpm before it starts missing. I first thought it was the fuel but It 's not the fuel as I hooked up a five gallon can with fresh gas and had the same problem .
Does anyone have any thoughts what to check. Engine has less than 300 hours on it.
