one seal is where the shaft exits the hull. if that seal is compromised then water enters into the shaft area. the second seal is the one where the shaft enters into the bilge area. the packing gland may be fine but the seal holding the packing gland is not.

Thanks 37Pacific. I wonder if most trawlers (or boats in general) have these seals? I've always thought that water was kept out of the boat because of the tight packing material forced tight by the packing gland collar. Can anyone shed light on this? It is important because several people have commented that the shaft log, cemented or glassed in tight, could be failing due to material/bonding failure of the log where it enters the hull, none mentioning "seals."

I have had boats with seals on the outside or the inside never both.

Double seals is a new concept to me. Sounds like the trapping of water in between with no flow would encourage corrosion.
