1. The joy was short-lived  because it was only a one minute run while I had the redrive drain line  disconnected.  Taking the drain line off gave the first clue.  No  sign that a drop of oil had ever been there.  The amount of oil in the  container after the run – zippo; not a drop.  I took off the feed line  and there was oil sitting in the fitting.  Feeding to a container, I  ran again for less than 30 seconds, and sent more than a pint into the  container.  Complete blockage inside the drive.  The prospect of  removing the prop, drive and disassembly is not a happy one.  
   

 
 
 
 
Al, something you might try  before taking the gearbox off (a pain to say the least).  Its been know  for such stuff as the silicon grey sealant to plug up the drains.  Yes,  unlikely that it would have plugged up the front one.  But, short of  taking off the gear box you might try removing the drain fittings - just in  the remote chance they could be plugged.

How about: remove the 3 fittings from the drive, blow compressed air from the top while plugging one or the other drain hole with your fingers. It may dislodge the restriction?
