I have had the PSS shaft seal since about 1987 or so. I am on my second one, when I had a bent shaft replaced a few years ago the yard swapped it out for a new one. The original had started to leak after 20+ years. I have been happy with it so far. The only maintenance it needs has been burping the air out after scuba diving under the boat and making sure the hose is adjusted right after an engine replacement. Joe Coquina

I installed it 3 years ago and, of course, it is like new. There is not a single drop of water coming through it. So if you like your bilge dry, this is, certainly, a way. It seems that people who have it, love it; most critical comments comes from people who don’t have it. I don’t regret replacing the traditional packing gland with the PSS. However, there is another way – you can use some Gore-Tex stuffing and have not-dripping stuffing box, as well. Since yours is seized, you need to replace it anyway. That route might be simpler. Not to mention that your future maintenance could be done on the water and without removing the shaft.

Though on another boat I saw the bellows become weak, add in the soft engine mounts and forward drive, and we had leaks. Mine came with the boat so it is at least 4 years old. I keep an eye on it as well as replacement options. At the boat show last year I saw a different option to the PSS. I was impressed with use of spring tension instead of bellows tension. I'll probably buy this product instead of the PSS when it is time. http://www.sailorsams.com/lasdrop-shaft-seals Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Apr 24, 2016 12:41 PM, "Patrick Davin via CnC-List" <cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com>> wrote: Sorry for so many questions, but I bit off a bit much on this haul-out... and I searched the list archives but didn't find much discussion of alternate stuffing boxes. My stuffing box is also seized and the packing needs to be replaced. On the LF38 the stuffing box is under the engine oil pan (v-drive configuration) with only 4-5" clearance to the sides for a wrench. I haven't found any wrench that fits yet. A prior owner recommended 3" C-clamps, and those work, sort of, but I can't get enough leverage - even hammering on it the seized locking nut hasn't budged. I'm starting to think that if I finish dropping the rudder this weekend then I should just pull the prop shaft (partially, because my cutless bearing doesn't need replacing) and get a new stuffing box. I know Wally swapped his out for a new Buck Algonquin nut style one - the same as the original but a slightly nicer newer model, and less corroded obviously. Unfortunately it looks like Buck Algonquin doesn't make the gland style packing box (with 4 bolts that are easily adjustable in tight spaces) for prop shafts smaller than 1 1/4" (ours is 1 1/8"). That design would be my preference. PSS dripless is about the same price though, and tempting... except for two caveats: - replacement schedule of the rubber belows is recommended at 6 to 10 years. I don't like that the rubber looks less durable than the 5-ply hose which should last 20 years. I could accept this shortcoming though, especially if it's 10 years. - PSS warns against having oil, fuel or any petroleum products contacting the belows. LF38 stuffing box is below the engine's oil pan. Oil or fuel is going to drip on it at some point! Even if you're pretty meticulous about leaks. I emailed PSS about this but haven't heard back. I could build a baffle / catch tray of some sorts, and just check it regularly. Has anyone else installed one in tight quarters and/or below an engine, and has it been a good decision? -Patrick 1984 C&C Landfall 38 Seattle, WA _______________________________________________ This list is supported by the generous donations of our members.
