I think you called me this morning. (Mercury EFI) If so, thanks. If I am correct, it will take "Quicksilver software version 5.0. As we spoke of the warning horn, it is NOT only there for low oil. The warning system serves many purposes. It want tell you if you are not pumping oil either. It will let you know the engine is hot, or block pressure is low. The ONLY way to properly diagnose the system is to plug the proper and appropriate software into the ECU and read the program. Most likely, the popit valve is not functioning, or indeed the block pressure is low. Also, yu have to read the Ohms on the Oil Tank level indicator and see if it is lieing to the ECU. It is a probe in the tank with a float surrounding it that moves up and down. If it sinks, it sends the wrong signal, hence Beeeeeeeeep. In addition, the block pressure may NOT be low, but the sensor is sending bad info to ECU. To many other possiblilites to list. We do have all the software needed. I will be glad to help you. And, thanks to the others for recommendation.
