Alarm beeping

My alarm beeps twice about every minute when it is running. Don't see anything wrong. What would cause that?

    Oil pressure sending unit could be faulty

    Have a dealer that handles your motor pull the OBD error codes to see what the alarms are for.  I had a similar problem on a 220hp Mercury I/O with a 4.3 MPI motor.  The codes showed low oil pressure and low water pressure.  They put Mercury's highest quality synthetic oil in the motor with a racing filter which allowed us to put in an extra half quart of oil in the engine.  Also put in a new water pump.  The boat runs great now.
