The PSS Shaft Seal is the number one selling marine mechanical seal
worldwide and is installed as standard equipment by many of the worlds most
reputable boat builders / yards. The PSS Shaft Seal is also recognized as
the premiere retrofit (aftermarket) seal on the world market. Certified by
Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages
and value of installing the PSS as it eliminates the maintenance, constant
adjustment & cost associated with traditional packing type glands. Aside
from these benefits, the PSS Shaft Seal helps to eliminate water in the
bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20mm) to 6" (150mm).
The PSS Shaft Seal is a mechanical face seal that is created between
the flat surfaces of the rotating stainless steel rotor and the stationary
carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft
in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This
compression (pre-load) maintains contact between the faces and allows the
PSS to compensate for the thrust from the propeller. The carbon flange is
bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The
stainless steel collar is sealed to the shaft by two o-rings that are
recessed into the bore of the collar. These o-rings rotate with the shaft
and stainless steel rotor and do not experience wear during operation.
**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.
PYI suggests as preventative maintenance that the PSS bellow be replaced in
six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."
Bellows may need to be more frequently inspected in an environment where
non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.
The Maintenance Kit includes the items you need to properly maintain your
PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings,
five (5) set screws, four (4) new hose clamps and an allen key.

bought Ecoflow pro originally for RV trips... now its a lifesaver for remote work and more.... thought about getting an extra battery for outages....
real deal and super reliable
Great backup power for essential home appliances during blackouts!
Hooked up my mercrusier engine to the Simrad and it's like having a boat dashboard on steroids. The ecogps function's a lifesaver, helps me get the best trim and rpm for max mileage. Love that I can see my fuel range on the chart and track fuel usage trip by trip. Customizable screens and side bars are a plus. If you can't find the info on this, you probably don't need it. And shoutout to their support team - the guy I talked to knew his stuff and helped me out! When I ordered, it came 2 days later! No waiting around. Great buy!
I've been wanting something like this for a year but not sure how to make it work for my van. I'm excited to set this up for my van
Happy and satisfied with my order
EcoFlow BLADE has transformed my lawn maintenance! 5 stars! ⭐
I can't believe I didn't buy this sooner. Furuno exceeded my expectations in every way. Bang for your buck!
The helps me manage wattage on my circuits due to extra air conditioning use while waiting for HVAC system repairs 🥵
It's a lifesaver for my off-grid office, ensuring seamless operation. It's also a must-have for camping trips, and it even powers my starlink dish flawlessly. No hiccups whatsoever.
Gives me peace of mind
The detachable design of this Wave 2 battery makes it convenient to carry or stow away. This is a fantastic addition to my setup!
Switched from the Lowrance HDS carbon 7” to the 9 inch NSX 3009, and what a difference those 2 inches make! The screen's clarity, especially in sunlight, is impressive. Plus, the touch controls are so much more intuitive than the old buttons. We mainly fish in inland waters, and this feels like a major upgrade. Still exploring the chart plotting, but so far, it's been a great experience.
