cutlass bearing on CD 28

[wayne grenier]

Hi-I am looking for advice-the cutlassbearing on my 1975 CD 28 sailboat seems to like sliding out of the stern tube until it hits the propeller-I have a 1"dia propeller shaft and used an exact replacement cutlass bearing-a morse 1 1/4" outside dia bearing-there was no set screw nor are their flanges on the bearing-I simply put some marine tex on it and slid it into the stern tube-I then built a collar of epoxy around the 1/2" of the bearing that protrudes from the stern of the boat-the cutlasss bearing is 3" long-so 2.5" of it are into the boat- and there is a lip in there that stops it from sliding in further-if we do the math-we see the brass portion of the bearing is extremely thin-about 1/16th"-so I doubt I could use a set screw to secure it in place-I could crush the brass with my hand-no problem if I tried-on the other hand-the fact it slid out another inch sometime last summer-didn't seem to bother anything-I cannot turn the bearing by hand-so I wonder if I could just "goop" it again-something has to hold the bearing in place-if the engine is doing 2,000 rpm and the bearing is new with no wear=-what keeps it from spinning inside the stern tube? We have a good propeller shop here I will ask-but I was just wondering if any onle else has dealt with this-thanks-

CD used 2 pointed set screws through the port side of the shaftlog just dimpled into the brass of the cutlass bearing.Probably some goop also.
