Reply To: Water Lubricated Shaft Seals

Nick,
Thanks for that. I was hoping you might have inspected an old seal during your change over. Anyway I launched and haven't sunk yet. You're right though I pulled back the seal to seee if water was coming up the stern tube and wow it fairly flows in. A complete failure would be catastrophic if unattended, but I think this would be very rare, more likely a gradual leak with excessive wear would be likely and now with the knowledge you've supplied the answer I think probably would be to tighten the emergency ring when unattended until sorted.
Happy sailing (afloat!), Alastair
