Below is a picture of my shaft seal
. I'm a bit confused how to maintain this. Don't think it would have packing, as there is no way to change or adjust it. The red arrow points to a grease nipple. So far I have added marine
grease every now and then to it and it have had no problems (had the boat for 2 years). Always added so much that excess starts to escape.
Now, doing spring maintenance
, I have pumped a lot of grease without any starting to ooze back out. At the same time I noticed the shaft outside the boat is oily. I'm starting to wonder if I have ruined the seal and if the stern gasket
is blown... I know that the standard dripless systems use oil
in a reservoir to fill the seal, but this has a standard grease nipple and no reservoir attached.
If anyone recognizes this type and can point to me how it should be maintained, I would be grateful. The boat is still on the hard
, hope to splash in the next week or so.
