Alarm sounding at higher RPM in neutral

[kenmyfam]

2006 5.0 MPI Mercruiser.
Alarm sounding at over 2500 RPM when in neutral. All fluid levels are OK and temperature and oil pressure are normal.
Is this a thing that happens in neutral ???
Not ventured further than the dock at this point until further invetigation.

Revving the engine in neutral? Yes that is normal to have a warning horn....If in gear then there's an issue.
Item number 20 is the gear Indicator switch that controls that, https://www.mercruiserparts.com/bam/subassembly/31851/11681/350

Go for a boat ride and enjoy the day.

Thank You so much for the quick response. Will be heading for a ride shortly. This is our 2nd season with this boat. Obviously I didn't do this last season !!!! Took me by surprise today.

Is there a reason you rev it that high in neutral?

No. I obviously didn't do it last year. Just had throttle in faste idle position at initial start up and gave it a "blip" while it was there. Won't be making a habit of it.

There would be lots of exhaust bubbles in the water.----Water pump does not pump air.----You have installed a new impeller since you got this boat ?

New impeller last season, pumping like a champ before launching this season. just back from a wonderful afternoon on the lake. All is well.

Shouldn't need to fast idle with an mpi

Just got back from a fantastic afternoon on the lake. All is well and no warning horns when under way. temperature, oil pressure and all the gauges reading normal. Thanks again for the reassurance and advice.
