While out on lake Saturday the engine failed to start a couple times when I stopped the engine. When I turned the key nothing happened then after turning the key a couple more times the engine started. Third time it happened it never restarted. There is no power at all - couldn't use trim unit to lift engine up either, no lights, horn etc. Had to get towed in. Checked fuses all look good. Could this be an ignition switch problem or the emergency kill switch problem. One other note when I finally got home I noticed the dash lights were on (key still in the on position) so apparently some power was getting there so I tried the trim and it the dash lights went right off. So that made me think maybe it was the battery extremely low. Checked battery out and it also is good and charged. Any suggestions?
