Silly question but are both your motors running?
Yes both engines are running, I was told but not confirmed that in 2017 this was a known problem and changes were made. I have never ignored the warning alert and operated the boat. this started two years ago. Still a mystery for me.

How old are your batteries?
Sensors are VERY voltage sensitive.
It doesn't report as a critical error, so if it were me, I would make sure, my batteries are in good condition and fully charged and then do a full power down of the engine computers. So shut the breakers in the engine room. Then turn all back on and restart.

I had this End Stop and other steering issues for several seasons. After connecting a G3 and running a Live Report that I shared with Mercury, they condemned the steering motor. Problem solved? For a while. Alarms came back and I discovered the the stbd Drive Position Sensor (on the pod) had some water in it and was confusing the Can Bus data lines. Problem solved? For a while. End Stop alarms came back this season. They were going off at totally random moments like when the boat was going dead straight in Auto Heading mode. I was able to trace the issue to a loose connection at the stbd CCM using the 'wiggle' test. Summary: This alarm is hard to pin down. Pay attention as to when it occurs and note ALL variables at the time. When it does occur, does it clear or is the alarm 'sticky' and stays on the screen. If sticky, once you shutdown and restart, does it clear? Does it recur again afterwards? A Zeus tech onboard with a G3 running a Live Report to capture the alarm when it goes off is very helpful. BTW, does your steering wheel center with key on? If no, steering motor is suspect. Do you always turn on the stbd key first as you are supposed to?

I thought the stbd key first was to clear any errors, not always a hard and fast rule...
Not an absolute rule, just the recommended procedure from Mercury and Cummins. Stbd key first, then port key, then stbd engine, then port engine. Forget where I read it. The stbd CCM module is the master module which initiates communications with the balance of the Smart Craft/Cummins communications (or so I've been told). You may notice how your wheel 'centers' when you turn on the stbd key. This is an indication of the stbd CCM getting things ready.
