I then tightened it until I felt it bottom out against the shaft. Then I backed it off about a half turn and sealed it with liquid electrical tape. No more grease comes out that hole
Any opinions appreciated. Howard

There are several reasons for that hole you decided to plug up. First one,........as heat or friction occurs the grease is allowed to expand and push out thru the paths of least resistance. Thats normal. Grease (oil suspended in a gelatanous media) is what provides lubrication. Blocking its exit path does not make a better lubrication system. Water and grease will mix. Its an accepted part of driveline operation.
Second one,.....You should be taking your flex assy apart after every run. Then clean and regrease. Not on the second or third. Its part of a maintenance plan you should adhere to and ensure happens every time. Other wise you will break drive lines due to mechanical failures. Lose a couple $30 or $50 props and it will become engrained. Comes with experience.
