I got my Ultimate FX 15 tandem a few months ago from Austin Kayak. They had a slightly used one with the rudder kit for the same price as a brand new one without the rudder kit, so I went with the used one. I've used it a handful of times since getting it and during my last use I noticed a problem with my rudder: the black plastic part that the long pin goes through to hold the rudder to the bracket on the boat was cracked and a piece fell off. The rudder still works but it's much more wobbly now. I have definitely not hit anything with the rudder and I remove it every time it transport the boat. I suspect it was damaged during shipping since the rudder was on the boat when it arrived, but just wasn't noticeable. I contacted Austin Kayak to see if they had parts, they didn't and said I would have to replace the rudder kit ($300, NOPE). I asked them to contact Native to see if they could get a part through their rep and Native's answer was also to replace the whole thing, which is quite frankly--ridiculous. It is clearly a part that can be replaced--it's held in place by 2 small alan key screws.
SO, looks like I'm gonna rig something up myself. Just wondering if anyone else has had the same issue and what you did to fix it.
