The 1977 Riviera I am restoring has a Hallcraft Rudder assembly. The boat sat for many years and the Rudder has a lot of slop in it. I disassembled everything, cleaned it up & replated the Rudder. There was no shaft seals installed. The Grease Fitting on the Shaft Log is good. Do I just pack the snot out of this with waterproof grease for a water seal?
