OK, new batteries but what voltage do you have at terminals?  You should have a resting voltage above 12.6 volts.  Test after battery chargers have been off and the "surface charge" of the batteries has dissipated.  Turn off chargers and run something to "tax" the battery for a couple minutes before testing voltage.
Are you not seeing displays on Vessel View and dash gauges?  If so, it is likely the engine ECM feeds that are missing but I would think that the ECM should reset with batteries off for a period of time.
