Pirate, you may be right, but that is not the whole story, because, on the same boat some pins (grey, black, whatever) last a couple years, while another pin lasts a couple miles.
Clearly, there is considerable variability in pins. One could argue that if a pin has not broken, don't change it--the old adage, "if it ain't broke, don't fix it," applies here. Well, maybe. After 1.5 yrs, you are pushing it.
Agreed Keith. My hypothesis is based on personal observation of my friend Mickey's rudder system vibrating as he was peddling with me down a river so I am convinced that there is just too much slack in the system which allows this unwanted movement. I might argue that an even thinner or weaker pin than usual will bring on failure even sooner whilst an unusually good combination of pin and hole diameters will ensure a more lasting set-up. My efforts were aimed at shimming out the slack to bring the percentages back in my favour. I always thought bushing the system would be a far more efficient answer but was not prepared to take that step until after the warranty ran out.
Has anyone experienced a pin failure with the 2011 rudders yet?..Pirate
