I have an 2007 Evinrude E-Tec 175 HP. About 6 months ago I had problems starting this engine. The ignition would always come on but sometimes the engine refused to fire. I eventually had the starter motor replaced. Today I got the same symptoms as I had 6 months ago, and had to come in on the kicker. Back on land I have now worked out what is happening but cannot explain how this occurs. Seems utterly bizarre to me but if anyone knows the cause let me know. The engine will ONLY start in the tilted up position. It will not start in the vertical position. This is consistent and repeatable. Riddle me that one!
