My 125 h.p. 2004 merc runs nicely for 20 or so minutes and then bogs down to two cylinders.This happens each trip, when the engine starts out, its fine and then the same issue occurs.Any ideas would be appreciated. Thank you Andy
when it bogs down try priming the primer bulb, if it doesnt pick up that eliminates a fuel problem. to me sounds like a stator problem. Possibly the switch box.
