PSS PRO Shaft Seal - For 32mm to 80mm Shafts
Product itself seems to be great! We installed the shaft seal with recommended 3/4 inch compression and it leaked terribly. PYI suggested increasing compression in 1/8 increments and it took another 5/8 of an inch compression to stop the leak under a load. I talked with another installer and he said he always has to add at least 3/8 more compression to almost every install. It would be nice to know that in the beginning as I have to take apart major engine components to reach the seal.
I shopped around and found this part a lower cost, but the help I assistance I received and exact description of the parts was well worth the cost. Happy to support companies that provide great customer service!
I have upgraded all the auxiliary cruising and racing sailboats i have owned with a PYI Packless Sealing System. they have been giving me great performance for 25 years, and I expect the same on my first twin engine trawler.
Great! Fast delivery.
