2002 mercruiser 5.0 mpi 2 beeps per minute alarm. No smartcraft gauges. I know it can be a whole list of things but i figured someone can help me narrow it down because it beeps twice when i click the key. Usually its only one beep. This beep also comes on twice per minute after i start it and its running. I changed the iac already and it has a new ignition coil module. Don't think its the water pressure sensor because it beeps twice before i even start it.
