It's funny how every 6 months or so there's a post that suggests that this thing is responsible for sending boats to the bottom.twice the set screws came loose and the two graphite plates slipped apart before to long I found my bilge pump running constantly and my floor boards floating.
Mine wouldn't tighten on the shaft, because it wasn't threaded all the way through the stainless collar.@tkwhalen there are two set screws in the sliding stainless collar and each set screw is stacked; you are supposed to put the first one in, tighten it, and then put in another (into the same hole) and tighten it against the bottom screw to lock it. How two (locked) set screws came loose? I suspect the installer didn't RTFM.
As for the leak -- just loosen the screws and push the steel collar against the seal face more firmly. BTW, the best dripless seals (IMHO) aren't sold in this country: Search the web for Deep Sea Seal Manecraft Wartsila
PS - PSS seals need to be "burped" to let out the air when you put the boat back in the water. If you don't do that it's possible to damage the facing.
So does mine -- and same for my prior boat. But I burp it anyway just to make sure there is a thin film of water between the mating surfaces.PSS has had a breather tube for years. Mine is one of the first series that had them.
No burp for you.
Defective. I'm sure they would replace it and overnight the shipping for free. PYI is a great company to deal with.Mine wouldn't tighten on the shaft, because it wasn't threaded all the way through the stainless collar.
It was a simple fix, ran a tap through, but would advise anyone that buys one to run the set screws through first. You pay enough for them ,QC should be a little bit more awake.Defective. I'm sure they would replace it and overnight the shipping for free. PYI is a great company to deal with.
