I originally thought it was the lower octane fuel (87) my wife put in the boat that caused it but 3 tanks of (93), new inline fuel filter, new fuel/water separator, and a can of SeaFoam and it still tends to surge around this RPM. Fluctuates about +200 rpm and then back down. It's not horrible and most people on boat don't notice but I do. Starts right up and runs good below and above the stated RPM above. Runs great at WOT.
Any suggestions where to go from here? I replaced the above parts as they were cheap and easy to change and most likely needed changed anyway.
I did notice the alternator belt was so loose you could turn the pulley while engine was off and tightened that, I realize that probably had nothing to due with the surging but a little FYI.
