Leaking Rudder Stuffing Box

On my 1977 morgan I get a persistent leak at the rudder stuffing box. I have replaced the flax with everything on the market. I have discovered the threads on the post were cross threaded by a prior. Any ideas ?

Re: Leaking Rudder Stuffing Box

Replacement of the stuffing box if the obvious solution if the rudder shaft is unscored and smooth and not bent. Close examination of the threads on the main body of the stuffing box should reveal if those thread are undamaged or compromised. If they are okay than finding a new undamaged replacement nut is an option.
- - To guard against a serious situation should the rudder be lost or seals fail I built a "sea chest" out of plywood and fiberglassed it so that any water leakage/flooding would be contained in the sea chest and not flood the ship. A simple automatic small bilge pump placed in the sea chest removes any accumulating water due to leakage until I can replace the whole bearing/seal assembly.

Maybe we could use something like this to cut those fouled threads off.

Re: Leaking Rudder Stuffing Box

If you have enough room/patience try using a small triangular file and go around the threads....keeping the edge of the file in the is tedious as all get out.......this was taught to me by a 70 something Port may work

Re: Leaking Rudder Stuffing Box

IMHO if the threads on the post and not the nut are shot, pull the boat and replace the post fitting and nut fitting. If only the nut threads are crossed up, you can get away with dropping the rudder using a halyard block, disconnecting the quadrant on top of the rudder post and sliding the rudder down so the nut clears the top of the rudder post and QUICKLY replace the seizing nut over the rudder post. Not sure how the Morgan rudder is configured. If the rudder sits on an extension of the skeg, it will be easier to pull the boat to affect the repair. If the rudder is free hung, you may be able to do it in the water. Don't tighten the nut until you have attached the upper quadrant and repacked the gland. Easy-Peasy but you may take on a bit of water.
Personally, I would pull the boat and replace the whole assembly... then you have no worries. hope this helps... Capt Phil
