A reminder for those of you who run a Volvo Penta shaft seal that uses a water nipple. While you have the boat out of the water replacement of this regular maintenance item is easy and quick. I pulled mine this winter and the OEM brass fitting fell apart when pulled. Corroded. No big deal on the hard, but in the water I would have had a big hassle requiring a haul. Here is a picture of the newly installed fitting. Nipple installed and collared by an application of thickened epoxy. FYI, the good folks at Annapolis Yacht Sales parts department sell a kit for $25 that includes the nipple, the epoxy, some cabosil and instructions.
