Add my name to the list of enthusiastic PSS users. A dry bilge means a dry
boat (no dampness, mildewing, etc.) and a sweet smelling boat. A truly
worthy advance in design. One word of caution. Some boats (like ours, a
Lord Nelson Victory Tug) have the stuffing box casting designed and located
to serve as an intermediate shaft bearing, with a long hose running aft to
the shaft log. If this is the case, it is imperative to leave the casting
in place, removing only the packing gland and locknut, and installing the
PSS directly on the threads at the front of the casting. You can tell if
the casting functions as a bearing if it is fixed rigidly to the hull with a
bearing hanger or some other similar device. It will also have a hose
injecting cooling water into the casting. If your stuffing box fixture does
function as a bearing, do NOT remove the whole casting and install the PSS
on the shaft log instead. You will generate shaft lash that will cause the
PSS to leak like crazy, and perhaps damage or destroy the bellows. That will
sink your boat.

Otherwise, a fine piece of equipment.

Hi,

I was at a boat show last week and one of the vendors was offering a
dripless shaft seal.
The web address is http://www.pyiinc.com/?section=pss_shaft_seal&sn=1

Has anyone had any experience with these either good or bad

Thanks

Kevin

And that is precisely why I will not install another one on a boat
that I own. I installed a Lasdrop on one of my old sailboats and it
preformed exactly as advertised but I was appalled at the relative
fragility of the unit compared to an old fashioned shaft log.

I have a PSS seal on my boat and you can add me to the list proponents.

I did have a porblem with shaft vibration when I first bought the boat
where the prop shaft flange was not centered on the Transmission
flange. The PSS seal never leaked a drop!!

The vigration and the shaft hitting the hull at certain RPMs was what
made me fix the porblem.

The only time I have encountered issues with the PSS was in the case of a
long shaft, typically in trawler designs. It simply did not work well, and
we reverted to a standard gland..
