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
