Using the right tools and some WD-40 I managed to get the rudder apart. Here are the metal pieces that need to be straightened.
And here is the critical central plastic piece that holds the rudder to the boat and allows the blade to slide up and down. It’s seen better days. I’m going to see if my Maker friends can cut a new one or if we need to purchase it from the manufacturer.
I’m currently researching the deck cording to see if I can do better than $.50 per foot.
