"THE PROBLEM - When the boat starts it runs fine until warm then stumbles and runs rough. If you supply 12 volts to the coil it runs fine. We have replaced the entire system (plugs,wires,cap,rotor,wiring harness to the engine and control unit,resistor, Alt (prestolite original to single wire ARCO)coil and pick up coil. Tested the ECU and it passed. The mechanic working on my boat is a professional marine mechanic and a friend. He has stopped charging me for the work because he has never had an engine stump him this bad for so long. (all year) ANY HELP would be appreciated!!"
