Mercury 1B484936 75 hp 4 stroke 2007

I’m getting 4 beeps every 2 minutes. The charging system is charging 14.3. With no draw when engine is not running. I have found delaminated fuel lines on the inside of the lines. Guardian system troubleshooting guide says its either low oil pressure, bad oil pressure sensor or water in the fuel. Can anyone help? Thanks !
