1996 8V92TA's with Allison's in a Hatteras 52' CPMY. First time out for a legit sea trial. Ran out of fuel on main tank, after switching to another tank and getting her going again I had high transmission oil pressure (see photo, 220+) readings on Port motor (which had stalled). GPH was also 3-4 for low idle setting (limping back to the dock as fuel gauges are questionable). Temp remained inline/consistent with Starboard. Voltage was also reading low. I checked oil on drives which were totally clear and a good reading on the sticks. Replaced the o ring on the port dipstick as it had no suction. When not under load at the dock I could not repeat the issue. Any thoughts on what could be wrong, places to start?

Low voltage or bad ground can really mess with electronic readouts.
