I don't know if this was mentioned but I have been told previously that too much oil can reduce oil pressure. The story goes that you can get foaming in the oil pan preventing proper pickup.
My 7.4's hold 7 quarts of oil. Perhaps double check you're supposed to have 8 quarts before you start adding more?
It can but if we stick with Mike's story......it did fine on the sea trial. So unless someone added a lot of oil to it between the sea trail and when he started experiencing the problem my money is that the pump is running out of oil. A mismatched pan and pump pickup fits the symptoms.
