Yamaha F115 four stroke rough idle question
I have a 2004 Yamaha F115 four stroke that has me baffled 
It runs great at just about any speed except low idle / in gear (out of gear, no issues).
In gear, it idles rough (and sometimes dies) and there's a slight hesitation (bog) when first accelerating. The bog lasts just a second, and then it runs fine all the way up through full throttle.
I've replaced the ICV valve, the VST filter, rebuilt the fuel injectors, installed a new thermostat, replaced the fuel filters, de-carbed the motor, run Yamaha Ring Free in the fuel, installed new primer bulb (that stays solid when running), new plugs, checked all the fuel lines, and on and on - but still the same rough idle.
Anyone have any ideas???
