With the intent of an overall inspection, I removed the rudder yesterday.  Turned out to be pretty easy, oddly enough. :)

I'm going to brush the layers of bottom paint off of the bronze fittings to see them, remove the paint from the cheeks, and see if those are salvageable.  There's a bit of damage inside of one of them, but it might just be surface-level and fixable with some penetrating epoxy.  Also planning on putting new UHMWPE washers on the pintles and gudgeons.
