I own a 1980s boat no top rudder bearing and a stuffed gland as a seal.
I've discovered extensive pitting of the rudder stock in the region of the stuffing box. I'm assuming that it is crevice corrosion.
My plan of action is as follows. I'd welcome your thoughts.
1. Have that area of the shaft x-rayed to ensure there is no damage deeper than the visible pits. If there isn't:
2. Dress out the pitted area to remove any stress-raisers
3. Fill the area with one of the proprietary plastic metals and dress back down.
4. Fit a speedi sleeve using some sort of adhesive compound to ensure that salt water cannot get in behind the sleeve.
My alternative is likely to be a new shaft and fill rudder rebuild so I'm hoping this approach will work.
I'd welcome any comments or advice.
