Hi Kevin
I have had one for two years and love it. I think is well worth the money.

I have had these on two boats. They work as advertised. You do need to maintain the rubber boot and make sure it stays on. If they fail, they can fail catastrophically. Best, Steve |

Especially not having to hang upside down or draped over the engine to adjust the stuffing box. Having the dry sump is another advantage. Leanne s/v Fundy |

Practical Sailor gave them a thumbs up. Face seals like the PYI are more tolerant of problems than lip seals that other types use. Evan Gatehouse |

Add my name to the list of enthusiastic PSS users. A dry bilge means a dry
boat (no dampness, mildewing, etc.) and a sweet smelling boat. A truly worthy advance in design. One word of caution. Some boats (like ours, a Lord Nelson Victory Tug) have the stuffing box casting designed and located to serve as an intermediate shaft bearing, with a long hose running aft to the shaft log. If this is the case, it is imperative to leave the casting in place, removing only the packing gland and locknut, and installing the PSS directly on the threads at the front of the casting. You can tell if the casting functions as a bearing if it is fixed rigidly to the hull with a bearing hanger or some other similar device. It will also have a hose injecting cooling water into the casting. If your stuffing box fixture does function as a bearing, do NOT remove the whole casting and install the PSS on the shaft log instead. You will generate shaft lash that will cause the PSS to leak like crazy, and perhaps damage or destroy the bellows. That will sink your boat. Otherwise, a fine piece of equipment. Dick B.

I installed a Lasdrop on one of my old sailboats and it preformed exactly as advertised but I was appalled at the relative fragility of the unit compared to an old fashioned shaft log. |

I have a PSS seal on my boat and you can add me to the list proponents.
I did have a porblem with shaft vibration when I first bought the boat where the prop shaft flange was not centered on the Transmission flange. The PSS seal never leaked a drop!! The vigration and the shaft hitting the hull at certain RPMs was what made me fix the porblem. Matt |
