Re: Stus-List C 33-2: PYI shaft seal

[Josh Muckley via CnC-List]

I preferred the old PSS/PYI seals without the vent since it made one less
complication during install.  It added user responsibility...

The guy at the sailboat show didn't indicate that the last-drop seals were
more or less for power or sail.

I assume that both companies will provide critical dimensions for the user
to make measurements prior to purchasing.

I wonder if they were the older, original style that didn't have the water
vent tube. I believe you are supposed to 'Burp' the seal upon launch, to get
the air out. I have never done this, and never had any problem. I would
think you would have to really be spinning the shaft pretty fast to overheat
one of those to get them to crack and fail. I wonder if there were other
things at play to have caused that.
Just looked at the Lasdrop Shaft seals, and they look intriguing.  There are
3 styles, and they look to be geared toward power boats.  I wonder which one
is recommended for sailboats.

Re: Stus-List C 33-2: PYI shaft seal

[Rick Rohwer via CnC-List]

I agree with Josh, my PYI  would be perfect if it could be changed without haul 
out!  I am trying to imagine the circus in the rear stateroom of my 37+ if you 
tried this change in the water! 
The failure rate of this PYI system seems to be nearly negligible, the pressure 
on the mating surfaces is so minimal!  I wonder if a temporary perfectly flat 
shim of carbon with ears (or other slippery material)could be quickly installed 
that would replace the pressure of the plates against each other…..
Failure of the bellows, or the set keys, may well eliminate mechanical 
propulsion if you are off shore. 
In shore you would need most of that bilge pump capacity you had invested in.
I haven’ seen the “Sailor Sam’s” but I will watch for it.
I am also a big fan of this company so I am not running down their products, 
but cognizant of limitations of the system.
Love the Max-Prop thus far.

Re: Stus-List C 33-2: PYI shaft seal

[Marek Dziedzic via CnC-List]

I don’t have a 33, so I cannot comment on how it would fit. But I installed a 
PYI dripless shaft seal on my boat 4 years ago and I am happy with it.

As Nathan did, I replaced everything (shaft seal, shaft, coupling and the 
cutless bearing). You can do just the seal, but if you have to remove the shaft 
in the first place, it makes sense to replace it with new. You won’t need to do 
it for the next 7-15 years.

The standard procedure is to replace the bellows every 6-7 years, but from what 
I hear and see, very few people do that. I would suggest inspecting the bellows 
every so often and replace it when you think is the right time. I think that 
that period was shortened a few years back (legal issues?). The pro version has 
a longer maintenance period.

I would strongly recommend an extra $30 for the retention ring.. You put it 
right behind the SS ring that forms the mechanical seal. This is the thing that 
would keep your shaft in the boat if, by any chance, the coupling fails.

The breathing hose (the 3/8 one mentioned below) needs to go above the water 
line. In my experience, it would spill water, sooner or later. If you need to 
move forward and reverse abruptly and with some revs, the water will go up that 
hose and eventually would spill. One option is to install a bottle that would 
capture the spilled water (and empty it on occasion). I tried it for a while, 
but it wasn’t a good solution. In my case, I plumbed the breather hose into the 
kitchen sink’s drain. This way, any water that wants to spill out goes back 
into the lake and the bellows can still breathe through the sink.

The installation is quite involving ( a lot of parts to be matched and 
replaced), but generally straight forward.

Overall, I have a completely dry bilge. I did not use the bilge pump at all 
this season.

NB. There is yet another company making a similar product - Lasdrop.

Good luck

Subject: Re: Stus-List C 33-2: PYI shaft seal

Not sure regarding the 33-2 but I was able to just fit a PYI shaft seal in my 
34.  It took perhaps an inch or so more space along the shaft than the original 
stuffing box.  Once installed and assembled with the right pressure on the 
bellows I have an inch or so between the PYI and the end of the coupling.

I installed it this summer after buying the boat because the stuffing box was 
in rough shape so that needed replacing anyway - it was brutal getting the 
coupling off of the shaft (I had to cut it off with a grinder and then have a 
new one fit and faced to the shaft - which apparently is standard practice 
although I didn’t know that when I started the project).  So it isn’t a small 
job in the end.  Also, there was just nearly enough room so I had to assemble 
the PYI loosely with the shaft just poking through it, then put the new 
coupling in place and tap the shaft into coupling (one person outside tapping, 
the other inside keeping it aligned and watching for the dimple when it is 
slide in far enough).  I got a split coupling (it is actually only partially 
split) which helps a lot but it still take hammering on it to get it through.  
Definitely recommend the split coupling though and I am hopeful that I might 
have more luck pressing it off next time it comes to that.

The final task was running a 3/8” hose from the PYI up 2 ft above water line.  
You want to keep it as centered as possible so I went to the and then up 
between the cockpit and the transom inside the hull and secured it to one of 
the air vents with a few zip ties.

Doesn’t leak or get hot so I am happy with it overall.  But it was a big 
project and the bellows are supposed to be replaced ever 5-6 years I think.  I 
would definitely take a look if there is an option that doesn’t require 
disassembly of the shaft.

Re: Stus-List C 33-2: PYI shaft seal

[Bruno Lachance via CnC-List]

Yes, I did it 3 years ago. The first project was to replace the leaking 
transmission seal so I had to remove the coupling. I ended up replacing 
everything: seal, new split coupling by Buck Algonquin, new shaft and a PYI 
dripless.

 It is pretty tight but it fits, I think the new coupling is a bit shorter than 
the original.

If I had to do it again, I might just replace the packing with the last 
synthetic gland that is supposed to be more durable and pretty much dripless.

Good luck!

have more luck pressing it off next time it comes to that.

The final task was running a 3/8” hose from the PYI up 2 ft above water line.  
You want to keep it as centered as possible so I went to the and then up 
between the cockpit and the transom inside the hull and secured it to one of 
the air vents with a few zip ties.  

Doesn’t leak or get hot so I am happy with it overall.  But it was a big 
project and the bellows are supposed to be replaced ever 5-6 years I think.  I 
would definitely take a look if there is an option that doesn’t require 
disassembly of the shaft.

Have one on a 35-3, no problem getting it to fit.

Re: Stus-List C 33-2: PYI shaft seal

[Josh Muckley via CnC-List]

I have a Max-Prop, a R coupling isolator, R engine mounts, and I have a
PYI shaft seal - all the same company.  I generally like the engineering
and customer support and like the shaft seal fine.  That being said, I
would suggest taking a look at the Sailor Sam's shaft seal.  As the vendor
described to me at the boat show you can evidently replace the "packing"
(carbon rings) with it installed and in the water.  Some of the models do
not require the tension of a rubber bellows but rather have a physical
metal spring that maintains pressure.

Stus-List C 33-2: PYI shaft seal

[Adrian Humphreys via CnC-List]

Any 33-2 owners with the PYI dripless shaft seal?

Will it fit?

We're looking at overhauling the packing gland and considering replacing it 
altogether.

Thanks,

Adrian Humphreys
