2004 four stroke 75hp

Just bought this boat/eng and the warning buzzer is going off. My Dad has been the one driving it so I myself havnt heard it. The manual says low water or oil but it has oil and the water stream looks steady and is not even that hot. Does this model have a history of this issue or of bad sensors? Any help would be appreciated.

Need to get the engine oil pressure checked to make sure it is not a false alarm.
