I've got a 2006 290 sundancer - great condition - 2 new long blocks - question: I keep getting a "check engine" warning beep about something (we think its gear lube - but its not). we have no idea how to stop the beep! All fluids are full and engines are performing very well. My mechanic has gone over everything a couple of times.......can't find the source of the "engine warning". Any suggestions??
