Some pictures of the dropped lower rudder bush. When pushed back up the play in the rudder goes. My question is which mastic/glue to use to keep it back in place. I've managed to clean the old stuff off using an angled dentist tool.
The bearing on mine is held in place with a set screw.
When I wanted to increase the gap between the rudder and the skeg I used a B&Q nylon tap washer which I split across on one side and wiggled into the gap. It's been there 4 years showing no wear. Perhaps that would work here.
