We found it!!  1 problem solved and the morale in this house is much better today!!  The engines are back up and running–whew!!

The electronics installer was talking the situation over with another resource Mike contacted about the whole “engines not starting” thing, and they realized the problem is this switch labelled Engine Shutdown System.  Sounds perfectly logical, right?  Well the two settings are “normal” and “override.”  Who would have thought the switch needs to be on override all the time?

 

As soon as Mike got the call that they solved the problem, he had to drive down to the boat and fire them up himself.  Success!!  We are sleeping much better in this house tonight!

Now, just waiting on that inverter to fix the shore power issue!!  😉
