Going back to the beginning with this: The way this started out, I had drilled and tapped a grease nipple into the stern tube (aft of the rubber hose joining the stern tube with the stuffing box). I guess the pressure when I injected the grease found a weak spot in the rubber tubing and broke through. As a result wads of grease and water
came through the tear in the rubber hose. I also noticed some grease on the shaft where it exits the boat (cutlass bearing?...is that a problem?). I was told the PSS would not work
now because I will never get all of the grease out of the stern tube and this system requires water pressure. So, I am re-thinking my options and am now considering putting new packing, new rubber hose and pumping the stern tube full of grease again. I guess since the grease will enter the packing, would it really matter what packing I use. Anyway... appreciate any advice.
