Mercruiser 7.4L MPI alarm codes

[mjswan8029]

I have a new to me 270 with a 2000 7.4L MPI in it. I have been searching without any luck for a description of the alarm beeps and what they mean. I get 2 beeps when I turn the ignition, no alarms during cruise or past that initial 2 beeps.

Is that normal? Seems like only one beep would be normal?

Thanks!

2 beeps is normal when you first turn the key on. Ton of useful info re audio warnings and model changes in this 3.9mb PDF file. Go to pages 11, 12, and 13 for alarm info for your engine. http://www.mdmotors.ru/netcat_files...akteristiki_sistem__EFI__MEFI__MPI__alb_3.pdf

Did you get your answer? My 270 does the same with 7.4.
