Mystery Prop Shaft Gland

Yours doesn't look adjustable except for the amount of grease inside it - strange.

Try contacting someone at the Durour Owner's Assoc. Boat Classes
It's a UK group so you don't have to be bilingual
Seems pretty unique all right.

Yeah. The only adjustment seems to be pump in more grease? What gives? I'm pulling the boat in February for a bottom job. Maybe I should lose this thing.

I think I'd replace it with a conventional stuffing box.

Does it leak? I wonder if it's like a "bearing buddy" for trailer wheel bearings. It's a spring loaded grease cup for trailer wheel bearings. I think they work on the principle that there is always some grease pressure on the inside of the hub that keeps the water out.

I belong to the "if it's not broke, don't fix it" club, but if this thing is leaking and adding grease doesn't work, then it probably needs replacing.
