Water-feed or vent requirements depend on vessel speed and shaft-log configuration. Inspect the bellows regularly; PSS recommends replacement every six years. Use new set screws whenever the rotor is removed or repositioned.\u003c\/p\u003e\u003cp\u003eHave a qualified installer fit the seal with the boat out of the water. Use soap and water on the rotor O-rings, not oil, grease or silicone. At 12 knots or faster, provide the positive cooling-water feed required by PSS; otherwise follow the specified vent or feed arrangement. \u003ca href=\"https:\/\/www.shaftseal.com\/marine\/pss-installation-instructions.html\"\u003eReference\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eParts Desk Insight\u003c\/h3\u003e\u003cp\u003eMeasure the shaft and the outside of the stern tube separately, then check the available installation length.
