Re: Stus-List PSS Shaft Seal

[Marek Dziedzic via CnC-List]

The only reason for water dripping is to lubricate (and cool) the seal/shaft 
interface. However, the PTFE packing has low enough friction that you  don't 
need to lubricate. Hence, no need for dripping water.

Btw. the main difference between the normal shaft seal (regardless of packing) 
and the dripless (e.g. PIY) is that in the former the seal is beaten the shaft 
and the packing box and in the latter it is between two faces of the seal (the 
shaft does not participate in this seal). Having said this, I don't think your 
PTFE packing would score the shaft in any reasonable time. When it does you may 
have other reasons to replace the shaft, anyway.

I used PTFE Tefelon Braided Ramie Packing .I repacked my stuffing box  6 
years ago with itafter Spring launch I adjusted for approx. 2 drops/drips 
per minutethen after running the engine the drips would stopI loosen 
and got the 2 drops per minute again...after the next use of the engine, the 
drips would stoploosen one more time, ran the engine and the drips would 
stop.

So I stopped looseningran the engine for 2 hours .got into the 
lazarette and put my hand on the stuffing box and the prop shaft looking for 
heatboth were cold so I left things the way they were.  The stuffing box 
does not leak/ drip water although I understand it should.  I may be in for a 
big expense some day for a new prop shaft but in the meantime, my bilge is dry 
except for what comes down inside the mast when it rains.  I can live with 
that, we all do.

I would not change to a dripless stuffing box when a much simpler and safer 
option is available.as David said here before, repack your existing box 
with a quality product and you are virtually drip freeI did mine 6 years 
ago and it still doesn't drip...and I have checked and there is no heat on the 
prop shaft, stuffing box, etc.  I never worry about a catastrophic failure a 
PSS dripless stuffing box  can endure.

Re: Stus-List PSS shaft seal - now hoses > Diesel Fill Hose

Replace your fuel fill hose.  I hadn't thought about doing that until one
day when I was working in a locker, brushed up against the fuel fill hose
and noticed cracks.  I replaced it immediately, and then went about
replacing all of my hoses.

Re: Stus-List PSS shaft seal - now hoses > Diesel Fill Hose

[Nauset Beach via CnC-List]

Is there a method to test the condition of a diesel fill hose?  Something 
similar to wrapping a warm wet rag around an old sanitation hose?  As diesel is 
not as volatile as gas would  guess hoses carrying diesel would last longer… ?? 
 And it is not like the fuel was sitting in the hose as the route from deck 
fill to tank is nearly vertical.  

 

AFAIK - The diesel fill hose on my boat is original.  The exterior “looks” old 
but there are no cracks or any surface damage visible.  I have to replace the 
deck fill fitting this spring, but would rather not play with the fill hose to 
the tank if I do not have to.  Its path behind cabinetry makes it a royal PITA 
to access, and appears to require taking too much of the cabinetry apart.

Re: Stus-List PSS Shaft Seal

[Rick Brass via CnC-List]

You’re right Josh. The purpose of the vent is to eliminate the need to “burp” 
the air out of the shaft log when you splash the boat. And since the shaft log 
is not under pressure, other than the fact that it is a foot or two below the 
waterline, if the end of the tube is above the heeled water line there should 
be no water siphoned through it into the bilge.

 

How do I know this? I had a friend with an older Benneteau that had a 
“generation 1” PYI seal (no vent tube). His bilge was so dry he put spider 
spray into the bilge to fight the cobwebs, and I was pretty impressed.

 

When he sold the Benny (which was 15-20 years old with the original seal), he 
wanted to install a PYI seal in the replacement boat.  The new seal was a 
“generation 2” with vent. He called PYI and they told him that the primary 
failure mode for the early seals was that owners did not burp them and ensure 
the log was full of water. The water cools the seal and, I suspect, provides a 
little lubrication.

 

A PYI seal is on the project list for Imzadi, when I  finally need to replace 
my current packing in a few years.

 

What I have now is a “dripless moldable packing” sold by Western Pacific 
Trading, Inc. (phone 800-944-3501). The kit has some “Playdough-like” material 
with Teflon in it, and a lubricating liquid. You put one wrap of conventional 
packing into the bottom of the stuffing box (to keep the “playdough” from 
extruding when you tighten the box). Then you roll a hunk of playdough into a 
string, dip it into the lube, and wrap it around the shaft until the stuffing 
box is almost full. Top it off with another wrap of packing to stop extrusion, 
and tighten up the stuffing box until it does not drip. 

 

My first installation was in 2004 and it was dripless until a spin halyard went 
overboard and caused a bent shaft in 2011. When I replaced the shaft I put in 
new packing on general principals. While the boat was out of the water at the 
end of 2016 I messed with the prop and replaced the cutlass bearing, and when 
the boat went back in the water it dripped a bit. Suspect we disturbed the seal 
when messing with the shaft. Tightened the stuffing box and no more leak.

I forgot but someone else has mentioned in the past that the vent isn't even 
really necessary.  Just burp the seal after each relaunch.

 

You can eliminate the vent by plugging the hole with a small brass pipe plug.

As for old hoses that's why it is so important to close your through hulls when 
away from the boat.

BUT many of us have 30+ year old boats with the original rubber stuffing box 
hose plus other old hoses. You have to ask yourself do you trust $5 worth of 
old rubber hose to hold the water out? Crazy Legs has 3 sink drains, 2 sea 
water intakes plus the stuffing box. Don’t forget the old rubber poo hose and 
fuel hose! Put your hand up if you have original rubber hose somewhere! Check 
yours out, mine had cracks along the surface of the hoses and I wasn’t

Re: Stus-List PSS shaft seal - now hoses

[Dennis C. via CnC-List]

Hear!  Hear!  High on my list!  In the 1st 4 months I had Touche' I
replaced all the thru hull hoses, the alcohol stove hose, and all the
engine hoses.  The two I didn't think about were the fuel fill hose and
shaft log hose.  I was painfully reminded of the former after filling the
tank one day and smelling gasoline throughout the boat.  The inner and
outer layers of the old hose had separated allowing gasoline to find its
way between the layers.  The vapors seeped out of the outer layer.
Replaced it promptly.

I replaced the shaft log hose during the diesel re-power process a couple
years later.

Re: Stus-List PSS Shaft Seal

[schiller via CnC-List]

I put a PYI Packless Shaft Seal on Corsair in 2001.  It was a ventless 
model and it was important to burp it in the spring during launch.  It 
was still pristine when Corsair was scrapped last year.  There is 
nothing wrong with the traditional stuffing box but those who are 
concerned of the bellows failing need to consider that their stuffing 
box uses a very similar piece of hose that can fail as well.


We used similar shaft seals in the Aerospace Hydraulic Pumps that I 
designed for a lot of years (after I no longer designed things that went 
boom).  We used bronze nose pieces in lieu of the carbon and tungsten 
carbide but designed for 30,000 hours.  Our designs were from 8,000 rpm 
for electric motor pumps to 12,000 rpm for hydraulic motor driven 
generators.  Our low speed diesels really don't need the vent line.


Grace came with a standard stuffing box that was repacked in 2016.  One 
of my projects this spring will be to replace with a PYI packless shaft 
seal (with vent, I'm getting too old to stuff myself in lockers to burp 
seals!).


Both designs rely on a rubber hose to keep the majority of the water on 
the outside of the boat.  I'll go with the lower maintenance design.  
Just one engineer's opinion.

You can eliminate the vent by plugging the hole with a small brass

Re: Stus-List PSS Shaft Seal

[Brien Sadler via CnC-List]

It sounds like both options are good options. I guess now the question is how 
much I want to spend to stop the water from coming in the bilge. Last season I 
knew of two leaks I had letting water in the bilge the access plate on the 
water pump was leaking when I ran the engine and the stuffing box was leaking 
as well. The stuffing box was leaking at a rate of 84 drops per minute in the 
middle of the summer.  When I went to adjust the packing there was so much 
verdigris on the packing assembly that the jam nut wouldn’t budge. In addition 
the hose between the log and the packing was old and was twisting at the 
slightest force. To avoid tearing the rubber hose I left it alone since the 
bilge pump was keeping up with it and decided to tackle the job on the hard 
before next season. I appreciate the insights on both sides. Now I’m not sure I 
want to spend close to $250 for a dripless packing when I could replace the 
hose and flax for less than $50 especially when I know I’ll only own this boat 
a few years. Always decisions to make.

I installed one on Pegasus, I ran the vent above the waterline, and put a

prevent the carbon seal ring from burning up.

Re: Stus-List PSS Shaft Seal

[Eric Frank via CnC-List]

The PO changed from the original stuffing box to a PSS seal on Cat’s Paw 
sometime between 1980 (when my father sold the boat to him) and 2004 (when I 
bought her back).  That PSS did not have the vent tube option.  There was some 
wear on the carbon(?) face (that seals to the SS part) although no drips I 
could tell, but I decided to replace the PSS with a new one in 2009. The new 
one has the vent tube.  I routed the tube out into the left cockpit locker 
(always running upwards) and ran it up to just under the seat, so well above 
the waterline - have never used a bottle to collect overflow; if it occurs, it 
would just flow down into the bilge. The directions suggested sliding the SS 
part forward along the prop shaft to avoid continually compressing the rubber 
part of the seal, so I have done that each winter.  Test it each spring (in the 
water) running at full speed to check for leaks and occasionally during the 
sailing season. Never saw any.  Engine use is not heavy - probably 100-200 
hours per season, so perhaps that helps explain why no leaks.  But it certainly 
has worked well on Cat’s Paw.

Re: Stus-List PSS Shaft Seal

[Dennis C. via CnC-List]

Dittto.  I use Teflon impregnated packing in a standard stuffing box.  No
issues.  Drips slightly when running.  Dry when not.  I have the tools,
knowledge, diligence and flexibility to properly adjust it.

Buddy of mine has PSS drip-less in his boat.  We were making trip to coast
one day when his engine compartment ventilation hose became dislodged.  I'm
talking about the 3 or 4 inch vent hose with spiral wire in it.  The hose
found its way to the coupling.  The set screws on the coupling grabbed the
hose and wrapped it around his PSS dripless bellows.  Fortunately, the
bellows didn't rip but it separated the seal and the boat began to take on
water.  He managed to figure things out and save the boat.  Granted, if the
hose had been properly secured, nothing would have happened.

I see the major advantage of drip-less systems as keeping sea water and its
little organisms out of the bilge where they tend to become smelly.

Re: Stus-List PSS Shaft Seal

[Marek Dziedzic via CnC-List]

Of course, it is always “your boat, your choice”, but the PSS is not unsafe. 
Great majority, if not all of the reports of dripless shaft seals failing 
catastrophically are on boats where these seals were not properly maintained. 
Dripless is dripless (not a drop of water over 3 years; completely dry bilge). 
Any other solutions is _almost_ dripless. If you want a dry bilge, no other 
solution is as good (I am not trying to say that PYI is the only one). But the 
shaft seal is not the only source of water in the bilge, so keeping the bilge 
completely dry may not be possible. In that case, you have to pick your battles.

Re: Stus-List PSS Shaft Seal

[Brien Sadler via CnC-List]

This is why I love this group, lots of great experience to draw on. I’m 
reconsidering switching based on the advice. I never heard about or thought 
about the catastrophic potential with the PSS. It’s also significantly less 
expensive to keep what I have and re-pack. Thanks again.

Re: Stus-List PSS Shaft Seal

[Chuck S via CnC-List]

Hi Brien,

Have to share this. I don't know what the previous owner used in my 1990 shaft 
seal. It does leak slightly when I first launch and when running, but not after 
the engine stops. I've owned the boat fifteen years since 2002 and never 
tightened the packing. No, I won't take it apart.

I guess it is one of the newer packing materials.

Re: Stus-List PSS Shaft Seal

[Marek Dziedzic via CnC-List]

I have it for 3+ years. Installed it right after I bought this boat.

The vent line burps water, mainly when you switch reverse/forward quickly (like 
when docking). The harder you reverse, the more chance the water will burp 
inside.

Initially I tried to run it high, but there wasn't enough room in the engine 
room. Then I added a bottle. You can install a standard bicycle water bottle 
(and a holder). You can install a barb fitting in the top of the bottle and 
connect the vent line there. You will have to drain the water from the bottle 
every so often. I did not like the idea, so the next step was to plumb it into 
the sink drain. This is how it is now and it works well. You probably want to 
have it plumbed reasonably high under the sink and you want to have the vent 
line looping up from that T, so that any grey water coming from the sink cannot 
drain through the PSS.

My boat is different, so it may not work for you. In my case the under the sink 
cabinet is on the other side of a bulkhead from the engine (the overflow 
coolant tank is there, as well).

If you are installing the PSS, add the retention ring. It is worth the extra 
$30.

Has anyone changed to a PSS dripless stuffing box? I’m sold on the switch I 
just haven’t figured out how I’m going to run the vent line yet. Any 
suggestions would be great. Preliminary plan is to run it to a very small 
through hull at the top of the transom.

Re: Stus-List PSS Shaft Seal

[Josh Muckley via CnC-List]

I don't think you have to run it overboard.  It just has to get above the
water line on all angles of heel.  I didn't install mine so it isn't a
fresh memory but I believe mine runs into the engine compartment, through
the compartment roof and into the HVAC compartment under the companion way
stairs.  I can't recall how it is terminated.

I have a PYI (PSS) dripless seal now and generally like the engineering of
PYI products but I suggest that you consider the sailor sams last drop
seal.  I was quite impressed by the display at the boat show.  Of
particular interest as I recall was that instead of a rubber bellows which
could weaken the last drop seal uses ridged hose and a spring pack.  As I
recall, the carbon rings can also be replaced without having to pull the
prop shaft.

Re: Stus-List PSS Shaft Seal

[David Knecht via CnC-List]

I had  a PSS put in on my 34 thinking it was a good upgrade, but on my 34+ 
decided not to do it.  The reason is that if not maintained properly, you can 
have catastrophic failure of the PSS and sink the boat.  I replaced the packing 
with teflon on my 34+ 3 years ago and it was pretty trivial, has not been 
touched since and hardly even drips.  The worst that can happen is more 
dripping and then you tighten the nuts.  I recommend against it.  Dave

Re: Stus-List PSS shaft seal 33 mkII

[Bruno Lachance via CnC-List]

Nice pictures of the setup. Mine is quite different because the stuffing box is 
not the same, and i think my hose was longer than that and this may explain my 
fear of not having enough space. 
 
But an other lister, Paul Fountain which owns a 33 mkII, did this upgrade 12 
years ago and confirms that it fits, so i should be ok.
 
And as you said i will try to bring the venting line as high as possible, i 
heard of that one before and of course i will by all means pay attention not 
to create a  situation that could sink your boat That last one always applies! 
but it's good to have a refresh. ;-)
 
Thanks Marek!

I think you need about 1” (3 cm) between your old stuffing box and the 
coupler (if I remember correctly).
 
I posted a few pics from before and after. I had just enough room to put 
the retention collar in: 
https://www.dropbox.com/sh/8tlcy5k0rwf4dzc/AAA7LXt-UzZJn3F5o7h4n2ENa?dl=0. 
For comparison, the shaft is 1”.
 
As you can see form some of the pics, I put some paper towels around, right 
after installation. I recommend you do, too. For the first half hour, you might 
see a bit of carbon dust from the bearing as it runs itself in. A pain to clean 
up after. Btw. the clear plastic hose (fuel line) is not recommended as the 
vent 
line going through the engine bay.
 
One more thing – the venting hose burps water! You have to run it high 
enough to have the end above the water line (and you might be surprised how 
high 
it is). But almost regardless how high and long your venting line is, it will 
eventually burp. this happens mainly, when you switch forward and reverse in 
quick succession (like when you dock). Two options I know of are: install a 
water bottle at the end of that line and empty it occasionally or plumb the 
line 
into some drain (e.g. sink) paying all kinds of attention not to create a 
situation that could sink your boat.

Hi all,
 
I'm about o buy a PSS shaft seal for my 33 
mkII and i'm having a slight hesitation about the clearance. I'm not sure of 
the 
total lenght between the stern tube and the transmission and how long the PSS 
will overlap the stern tube?
 
I will also replace shaft and 
coupling so i might be able to go with a shorter coupling if necessary but i 
would really like to be reassure on this before i pull the trigger. I would 
also 
like to add a SS collar sold by PYI to secure the shaft but it would probably 
not fit? right?
 
Advices on the PSS project are also 
welcome.

Bruno,

We did this on Perception 12 years ago, tight but had room. Since empowering, 
and now just enough room!
