My 2017 115Ct Mercury outboard runs fine for 30 minutes then begins to spit and sputter. If I open it up, above 2200 rpm, it goes, da-ga, da-ga, da-ga. I have tuned it up, changed all the filters, changed the fuel even called it bad names. But the problem still exists. I suspect one or both coils are acting up. Or could it be the fuel supply pump modules? Anyone else have this issue?
