Re: Dripless shaft seal

I've had this happen. Really the only thing that fail that going to really be be a lot of water is the rubber boot/bellows. I wrapped it with rescue tape and it lasted 3 months with no leaks till I could haul out.

But that is why I replaced with a Next Gen II seal afterward.

Re: Dripless shaft seal

I have to go with the "rescue tape". My stuffing box hose tore in half and it got me home. The wind died and I was even able to motor into port. Granted, most have never seen a bigger ball of rescue tape, amazing what one can do with three rolls of rescue tape and a boat full of water

I used to have some toilet wax on board as well...I should probably revisit that.

I have a dripless seal on current boat. I had to move the ring further aft last spring as I was getting a fine spray under power, but no leak otherwise. I'm not sure if the retaining ring actually moved or the bellows lost some of their spring.

My opinion is that the bellow lost a bit of springiness. The bellows appears like new so I think it will be good for another couple of seasons.

One thing for sure, they are just as much maintenance as a conventional packing gland. Maybe more....

That's classic, hard to imagine a more fitting failure to have occur on a freakin' Rally Down the ICW...

Except, perhaps, for something like a jammed/stuck zipper on a cockpit enclosure...

;-)

What was the exact nature of the failure?

Re: Dripless shaft seal

JE: not sure. All I know is there was a lot of water. They were able to get it under control. They are proceeding ahead of the rally towards Beaufort to haul out the boat for repairs. Maybe they are going back to a normal stuffing box? Didn't want to probe

Re: Dripless shaft seal

Just when I was thinking how nice it would be to have a dripless shaft seal, you had to come up with the one good reason NOT to get one.
Thanks. lol

Back in the day, before PSS carried the "Shaft Retainer," the solution was to go to McMaster-Carr and purchase a two piece clamp on shaft collar;

I have a 1" shaft, let's say the distance between the shaft seal collar and my shaft coupling is 5 inches...

I simply split a 5" length of 1" PVC conduit in half, and fit it into that gap...

Does the job, no way that collar is going anywhere, hasn't scored or marred the shaft in any way - which might possibly tear or damage the O-rings if a new collar replaces the old - at a cost of perhaps 20 or 30 cents...
