I have another problem and hopefully you all can help me out again. Last weekend I was on the lake and no issues, boat ran fantastic. This weekend the engine light comes with the alarm. This happed while idling and on plane. Approximately 30 to 45 seconds after the engine is started, the alarm and light comes on. Water pressue / oil are good and engine runs smooth. While this was going on, I experimented with the ignition key. When the alarm came on I would turn the key just far enough to stop the alarm, but not kill the engine. With that being said, could I have a problem with the ignition switch? Also, the problem did go away later on in the day and never came back. I won't know if the problem is gone until the next time I put the boat in the water. I did put in a new cranking battery before this all happened if that makes a difference.
Thanks for your help in advance,
