Need help reading ddt

[Thumbtack]

I have a mercruiser 5.0L MPI bravo. (OM600000-OM614999)

There are two beeps going off every minute almost on the minute. The beep starts to go off only after the boat has ran for a few minutes and will continue to go off with the engine off and key in the run position. The engine itself is fine, there are no over-heats, low oil, low gear lube monitor, this is a beep that should not be there. I tried to disconnect the temp sensor, map, oil pressure, g/l monitor, knock sensor, iac, and tps sensors and it continues to beep even with those disconnected. I have also set up the ddt to see if that can tell me anything but that didn't really help, I have also tried to erase all faults but it still beeps.

My question, is there a way to read on the ddt what is happening?

Haha, I actually disconnected that and my depth finder because they also have buzzers and I didn't want to hear one over the other while trying to figure this out.
I haven't gotten anywhere with this yet after looking at it a few more times. Looking on the internet it seems to be one of the sensors could be bad but I can't see how to read it (if one is bad) on the ddt.
