Re: Dripless Shaft Seal versus Stuffing Box

I have the dripless seal. The original was leaking when I bought the boat and it didn't have the air bleed hose. I replaced it and not had any trouble with it since. It was replaced about two years ago. I plan to replace the bellows 7 to 10 years out per the manufacturer's recommendations. Seems a small price to pay for 10 years of a dry bilge.

Re: Dripless Shaft Seal versus Stuffing Box

had this formosa i own had a dripless seal, my formosa would have sunk many years ago. my old style stuffing box is awesome to modify when it is old and in bad shape and will still keep much of the ingress of water to a minimum.

btw, i am in zihuatenejo , guerrero , mexico at present--was a great sail and is a gorgeous place.

Re: Dripless Shaft Seal versus Stuffing Box

mark--one of the solutions for mine is to modify into a kind of dripless seal situation, only a modification of my present system--could well be similar to yours--
mark--please advise me as to what is the lip seal system some bendy toys are using?? sounds like a possible solution to mine....

I also own a Formosa 41 with a leaky stuffing box (though I suspect mine is an engine alignment issue).

What's this "kind if dripless modification that you speak of???"

Be nice and call then their right name and I'll give you a cuddle.

Mine has a PSS. I thought all did.

This is what I've seen on a couple of volvo-powered Beneteaus:

Tell me more about this awesome looking, device. Does it fit on a regular stuffing box, and if so where? How is it used?

I'm old school you see and don't have much experience using rubbers on my sha... um... nevermind.

Seriously though, how is this thing used and does it augment a regular shaft seal?

Re: Dripless Shaft Seal versus Stuffing Box

I have this shaft seal on my Jeanneau. It's a Volvo Shaft Seal, and it is dripless as well. There is annual maintenance (a little grease) and you have to burp it when the boat is placed back in the water, but other than that, it works well. The seal also has to be replaced about every 6-8 years.

Although it is a Volvo part, Jeanneau installed it on my boat, and I have a Yanmar engine.
