why would we be chasing low oil volume if both engines have the same amount of oil in them both engines have the same oil pan ,in that theory both motors should be reading low oil pressure, no?
If the starboard motor is running good I would Verify that with the mechanical gauge
Proving that the starboard motor, gauges and oil volume are functioning properly and eliminate any possibility of faulty equipment.
70 pounds of oil pressure at the sea trial would indicate a high volume oil pump and the oil pan being larger would be standard with that set up . I get that 8 quarts may not be enough with that set up but if one motor is running perfectly fine then I’d be looking elsewhere. Sounds like something let go ,oil pump pickup tube? That would be rare though . I would be getting in touch with the previous owner and investigating as much as you can about what was done with those motors and when it was done etc. If adding more oil to that motor works I would be very confused considering everything I said above but hey you never know
Again...the conditions have changed since the sea trail and when the problem first appeared. The owner changed the oil on both engines. Like 99.9% of us he did not measure how much oil he took out only how much he put in (8 quarts). If it is an oil capacity issue and both pickups were the same.....it would now appear on both engines. If the pickups are different it may happen on only one engine.
I'll bet the previous owner knows what is going on.
