And now...the right way to do it: http://www.pbase.com/mainecruising/pss_shaft_seal
"Maine Sail" has a whole gallery of how to do things right. http://www.pbase.com/mainecruising/boat_projects In my experience, he is dead on with every recommendation. I have found this to be the best source of accurate information for most projects, and he has lots of pictures, which helps a lot.
