Hey Guys, I have a 1977 Evinrude 115hp that I recently took to the lake and while running it there, the engine died on me. I've checked all 4 spark plugs on it and they are sparking. It is also getting fuel. This leads me to think it is either the power pack or the keyhole sheared. However, I am not sure which cylinder is the number 1 cylinder. Can anyone help me out on locating the number 1 cylinder?
