I still think the lowered oil pressure is a symptom, not a cause. Its the natural result of running at a lower RPM. In post #6, the OP says:

The difference between fwd and neutral or reverse seems to be the defining symptom, which to me suggests the reversing gear. A fouled prop would affect both fwd and reverse, but not neutral. A problem in the oil pump system would affect all three.

I recall some posts here in another thread some time ago about the retaining clip on the adjusting nut on the reverse band being broken or missing, allowing the nut adjustment to change.

It would be really informative to have RPM and oil pressure measurements in the following combinations:

Throttle at idle, shifter in fwd, neutral, reverse

Throttle at cruise setting, shifter in fwd, neutral, reverse.
