I have a rebuilt 1984 185hp Evinrude. Sometimes after pulling kids on a tube, engine dies at idle. Hard to restart. After starting it starts to die as I increse throttle. I have to gradually get to full throttle. It then runs fine for awhile. I have temperature guage on each cylinder head. No overheating. A friend mentioned maybe a bad coil. Seperate problem, VRO alarm for no oil is constantly sounding(short beeps every second). Rebuilder disconnected system no resevoir. I can't find wiring on engine. I assume part of the old wiring is grounding itself some where.
