from what I can tell the oil alarm does a beep beep beep this just is a constant beep that gets louder. mercs do have oiling issues from what ive read on line.
I did a quick search and all I could find is the merc has 2 alarms. Temp and oil. The oil alarm is know to give a false alarm as the oil float gets a leak and sinks. I'd have a marine mechanic look at it.
it is peeing but possible the maybe the thermostat not working properly. but the middle cylinder running way to lean all of a sudden makes me alittle worried.
