I have a 2005 Volvo Penta 5.0 GXi. While running along at no-wake speed today an alarm started going off. Not the not the loud continuous alarm you would expect from a temperature or oil pressure alarm, but a "Beep...Beep" once every five or so seconds. All gauges register as normal. I didn't drive around to see what might be causing it, because it about to pour with rain at the time and I was coming in to the dock. Any ideas?
