Seal for an underwater shaft, what can I use?
Seal for an underwater shaft, what can I use?
(OP)
I'm having to design A propeller but am unable to think of a suitable seal to be used to seal the shaft of the propeller. I thought possibly an O-ring or lip seal but they could quite easily give way and water seap into the boat.
Anyone Help?

I have a British sailboat that uses grease forced into the stuffing box by a permanently installed resevoir. The leak path is fairly long and the grease fill seems to work pretty well. Periodically tightening the cap on the resevoir forces more grease into the stuffing box.

Stuffing box does about 99% of applications.
Outboard motors use lip seals which often let water into the gearcase.
