I have a 2001 Mercruiser 496 Mag, standard output, Serial #OM061853 with Bravo II (OM124690) with Smartcraft Tach and Speedo. It is beeping twice per minute and also seems to run fine.

I've recently had a high oil pressure reading, with no alarm of any kind, and mechanic replaced the Oil Pressure Sensor (as opposed to Sender). This seems to have fixed the oil pressure problem.

Now I'm getting the two beeps/minute. The mechanic said the "codes" did not indicate anything wrong.

I've bought and borrowed all the manuals I can find, Mercruiser and Seloc, and poured over the sensors and wiring to no avail. I guess I should get the codes read again.

Can you suggest what I might look for in the ECM code readout?
Do you have any other suggestions?

Thanks
