Hi, I have a problem that may or maynot be unique. I just bought a 1979 evinrude 35hp remote controlled motor. The harness on this motor has a black plug with a five prong configuration. my boat has the standard red plug side mount controller. the plugs are the same style and shape and when the arrow are aligned they plug into one another. The motor starts and runs fine and the electric choke work fine also, but once started it won't shut off. I had to unplug the gas and wait till the carb runs out. Do I have to buy a new harness for the motor or is there something else that can be done. Sorry for the length, just trying to be thurough. the model # is: 35952A Thanks much....Robert
