I have a 1977 C 30. I think that in the near future I will need to replace the hose that connects the stuffing box to the fiberglass tube for the prop shaft. I searched the archives but did not see mention of the type of hose/diameter of hose/or material specs of the hose. I am hoping that someone has replaced their hose and can provide some information on the required hose material. Thanks in advance for the help. Regards John
