The problem is that the propeller, after the oil is good and warmed up, wants to go to feather at any RPM less than 1500-1800. Oil pressure is good at the back of the engine, have tried different governors, have changed props.

Sounds like the featherlocks on the propeller bulkhead. There are three spring loaded locks or "stops" to keep the propeller from going onto feather at low RPM. Remove the spinner dome and you will see them. Check to make certain they are extending. If they are it is the seal between the crankshaft and the gearbox. Was the gearbox recently changed??

Your problem is the oil transfer rings are worn out in the nose case. This is a common problem. The seal rings on the oil transfer assembly and the oil transfer sleeve are leaking too much oil to properly transfer oil from the nose case to the prop shaft to work the propeller.
The nose case can be removed and sent out for overhaul or repair without removing the engine. I assume that the engine has about 1200-1400 hours on it.
Central Cylinder is the best place to send it. There is a shop at Opa-Locka Florida
