I have a problem on a EFI 175 mercury runs 60 mph but not low speed. Hard to crank ,low speed starts performing around 2500rpm . Computer swaped all controls tested. Fuel good and clean. Will the stator cause this kind of problem. Resitance is not off much but a little diffrence in coils. Motor started to surge when backing down on throttle. It smells like it flooding at idel. Has been tested at several shops with no help. I dont like being a parts changer with out being sure.

"Computer swaped all controls tested."

Could you elaborate on what this means? I am afraid I do not understand this sentence.
