2012 90hp optimax

[FDE]

I was getting a solid alarm tone on my 2012 90hp optimax. I do not have or have access to a code reader. I replaced the water pump impeller, wasn't bad but I changed it anyway. I pulled the thermostat to check it, and the poppet diaphragm was torn so I replaced it and the thermostat. Now when I start it on a water hose I get 4 beeps from the alarm about 30sec to a minute after I start it. Never noticed it before. Does anyone know what it could mean? Thank you for your help.

Your owners manual will tell you the 4 beeps every two minutes is low oil or water in fuel.
