RE: Dripless Stuffing Boxes

I replaced my PYI dripless stuffing box in 2007. Had the tranny out, rudder and prop off so the shaft coupling could come off easily. It was an opportune time. My old PYI stuffing box had something like 4000 engine hours on it and was about 11-12 years old. Not bad.

Installation was not hard since the basics were set up as described above. Just follow instructions.

Bob Smith has told our MTOA group several times about some brands of stuffing box that have a catostrophic failure mode that is truly catostrophic. He had it happen to his boat. but it was not a PYI.
