My boat's rudder
is skeg hung, and the stainless mounting hardware
(gudgeons?) that connect the rudder
stock to the skeg has suffered from corrosion
on the inside surfaces.
I'm about to pull the trigger on having some silicon bronze replacements
machined, but I'm a bit worried about the stainless rudder stock having a galvanic interaction with the bronze hardware
The rudder hardware clamps down on either side of the rudder stock, with virtually no play between them. The pieces that clamp together look a bit like these: Imgur
I was thinking about making them a bit looser around the shaft so that I could somehow get a delrin tube between the two surfaces to isolate them, but I'm not exactly sure how to go about that, and don't know if its neccessary. I could try painting the bronze with some kind of low friction paint
, but I'm not sure what I could use in this application of how long it would hold up.
