Got up on a plane on Sunday and one of the audio alarms came on. There seem to be only two on this EFI engine and it was the lower pitched of the two. No de rate, no weird noises, just the steady audio warning. All gauges looked okay and engine was just serviced by the dealer.
I can't find any info that indicates what the two audio alarm sounds represent, but I hear both of them momentarily when I first turn the key on. I believe that part of it is a normal sequence before start up. BTW, this was the first time we have had this boat up on a plane. We normally run it at +/- 1100 RPM and take our time getting anywhere. (Maybe we should just by a trawler)
Is it safe to keep running and rely on the ECM to de rate the engine if there is a real problem?
Will the alarm be recorded in the ECM so I can retrieve it with a code reader?
