Hope someone has an idea. I have a 2011 mercruiser 5.0 mpi. Runs perfect but I get a single beep every minute. I checked with my Rinda Tool and it shows NO alarms!!! Everything from cooling temp to oil pressure looks great.
One thing my IAC valve shows to be open even off idle. Is that normal? I thought off idle it would be zero.
Worst comes to worst i disconnect the horn. I know the outdrive is tight, lube oil level good, water pump good. Last boat i had didn't have an alarm for 30 years and never missed it!!
