Intake warning sound for one second

[Anthonym2]

Hi everyone
Recently, while running the boat pulling a tube, the intake warning came on for a split second and then stopped. It happened twice. The amount of time that it was on was so short that as soon as I started to lower the rpm's it was over so I kept running. Engine temp and oil pressure were all normal. At what point do I worry about this? If it keeps happening is that something to be concerned about? Is this a sign that my impeller is going?
Is there anything I can do to troubleshoot that?
I have a 2007 sea ray 185 sport mercruiser I/O
Thank you

I'll assume its a Merc because its posted in the Merc section. Doesn't matter what the boat is but do need to know what motor and serial numbers are best?

What is a intake warning sound?
Maybe the alarm beeping?

Yes, that is my question. The intake alarm is what is going off, but only for a split second then stopped.

There is no 'intake alarm'. Is the buzzer sounding?

If it is the buzzer three things can make it go off oil pressure switch , temp switch , or drive lube bottle level sensor

There are actually more codes than just those three.
You need a code reader to know what is going on.

The reference here is a non-MPI engine... They only have 3.
