A couple of years ago we installed a PYI dripless seal on one of our work boats. We were so happy with the way the dripless seal worked we decided to make them standard equipment on our cruisers as well as the work boats. In the area of maintenance is where the dripless seal shines. No packing, no standing on your head, no special wrenches, just a periodic look and you are done. We are very happy with this product. Sincerely, Brent Morey We switched from the old style stuffing boxes with the packing gland to the new dripless PYI shaft seals a few years ago. We have not had one complaint about them. Customers are pleased that they do not allow water into the hull and that they do not have to be replaced every year. They are a definite plus for our line of sportfishing boats and we use that fact in our marketing plan. We are currently building boats for the U.S. Navy and they spec out the old style stuffing boxes. We have discussed with them changing to the PYI shaft seal and we even gave them a free sample to test. They are interested and may possibly incorporate them in future contracts. Sincerely, Randy Chabot I am writing you to order a set of PYI seals for "Audacious II," The last boat in our fleet to be outfitted. Our experience has been more than satisfactory to say the least! The first set we installed was in my old Mariner 32' Ketch. Not a super active boat, as in the twenty years she was in family, we only accumulated 145 hours on the engine (its only ten minutes from the slip to open sea here), but after the change to the PYI Seal, we had a dusty dry bilge all the time. In the case of our 65 passenger glass bottom boat "Holo-Holo Kai" things are much different. We installed the seals at regular overhaul in 1988. The boat makes a sightseeing trip offshore of Waikiki leaving every two hours throughout the day. She did this for a total of 13,140 hours on the main engines before we had to replace our first seal. This was due to having to run for about five weeks on a bent port shaft while we waited to get a new shaft from the mainland. Even under this abuse, the seal didn't leak, we just wore it elliptically, and badly enough that we felt it was best to replace the unit. The starboard shaft was still fine, except we thought the carbon was wearing a bit thin and so we replaced it too, as we only go to dry-dock every 18 months. In short, we think you have a very fine product, and we're very happy that you make it, as it surly takes good care of our bilges. Thanks Reginald A. White Just a note to let you know that I have installed a PSS system on my CS 30' sailboat. I have a 1" inch shaft on the boat. Installation was very simple and I now have for the first time in 10 years a Dry Bilge. May I add that when I was installing the unit and testing it under water I continued to detect some light misting/spray in the area by the engine and the stern post. Upon closed inspection, I noticed a small hole in the wet exhaust hose which I quickly replaced. I wonder if I had not installed the PSS system and with a constantly wet bilge area I may have never noticed the problem until I was in a more disastrous situation??? Sincerely yours, Brian Donovan |
