PSS seal
Hi Mike: I have not installed one myself, but I have talked to several who have and they report they work very well. That being said, I have found by experience, that teflon packing material and the teflon goop sold at West Marine and others, also works very well and is much less expensive. My Universal M25XP on my Catalina 30 does about 2-3 drips a minute when running and 0 drips when not. I have a completely dry bilge, as the engine heat is enough to evaporate the 3 drops a minute. In the end, that is the best the PSS seal can do, is give you a dry bilge, I have accomplished the same thing for less money.Good luck, Dave
