I have been getting 1 beep every 5 seconds.Occurs intermittently after a warm start, it also goes into limp mode. If i put it in neutral and back in gear it stops beeping. Also appears to be running rich, dumps a little fuel out the exhaust after shutdown. Oil level , oil pressure, watet temperature, outdrive level are all normal. When i drove the boat to the mechanic today the issue didnt happen of course. He scanned for codes but didnt find any. Any ideas???
