Howdy All -<br /><br />I have a '98 Johnson 115, Model J115ELECM, V4, oil injected, carburated motor with about 600 hours on it. Well maintained. Only problems I have had in the past was water in the fuel and sometimes the tachometer does not register.<br /><br />Yesterday, I was crossing the bay at about 4500 rpm when all of a sudden the motor missed a couple of times and then shut down completely. Fuel checked out fine, kill switch was not activated, plugs were not fouled. Checked the spark and found that I had no spark to any of the cylinders. Local marine mechanic told me it could be the optical ignition sensor, power pack or a bad kill switch.<br /><br />Does anybody have any other diagnosis? Also, how do I rule out what it could be and decide what it is without randomly replacing all parts that could be the problem?<br /><br />Thank you in advance for the information and have a great weekend.<br /><br />T
