Well, few days ago I realized I could rotate the swing keel mechanism of my B311 with my fingers. It is usually not hard but you do need a winch handle to operate.
Then I panicked when I could lift the whole mechanism by just removing the two screws holding the delrin collar.
So here are the pictures. Had not seen any pictures or diagrams with this second set of arm extensions but my guess is that it creates a better leverage by connecting it more towards the middle of the keel. Perhaps it was a mod from previous owners.
Anyway, the issue is that it is not connect to the keel and you can see the bottom bolt is still there so my guess is that something broke in the keel recently.
Have attached also pictures from the survey few months ago showing the keel partially lowered and the connection of this loose part to the keel.
Has anyone seen something similar and how to fix without a haul out?
