A bit of advice would be appreciated.
My starboard engine does not charge the battery. All parameters read correctly on the diagnostic software and readings are identical between port and starboard.
Except battery volts.
1) portside @ 1000 rpm reads 13.8 V.
2) starboard @ 1000 rpm reads 12.4 V. This does not increase at all. Motor otherwise performs perfectly.
Any idea where I could possibly start looking for the fault.

Inspect the flywheel and stator.....test the stator resistance and output. If those are good, you may need a new EMM. You can swap EMM from engine to engine and run at low speed to see if the problem follows the EMM. Only do this AFTER you have verified all other components in the system are good.
Also, you should post this in the Owner's zone for better coverage.
