Morgan OI 33 - Rudder shaft stuffing

I wonder if someone can help me with a question about a 1978 Morgan Out Island 33. Water is leaking in through the rudder shaft. I want to replace the stuffing but the manual I have doesn't give the dimensions of what the flax stuffing should be. I tried 5/16" but I could only get two rings on the shaft and still have enough threads to get the nut started. I tightened it down extremely tight but I still get a very small amount of seepage. Thanks for any help.

I used to have a Morgan OI 33 and now a Morgan OI 41 - 'both 1973 and both with the same rudder post seal configuration. I don't think I ever achieved more than two rings of packing, but I had success. Did you cut the ends of the packing rings at an acute angle? Did you place the cuts in the rings at 180 degrees from each other? I think doing this is critical, but you probably did this already. I know that the packing I used was always the same as I used for my stuffing box. 'take care and joy, Aythya crew

ok, thanks. It helps to know that 2 rings are enough. I've got it to the point where it is not weeping at all, just 'damp' on top and not dripping at all. I offset the rings by about 90 degrees. The next time I do it, I'll make it 180 degrees as you suggest. Thanks again!

I'd point out that rudder stuffing boxes generally don't take as much packing material as prop shaft stuffing boxes, as their working situations are quite different. The prop shaft is under more movement more of the time than a rudder post seal, which is relatively static in comparison.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
