whilst rooting around in the engine compartment looking for space to install a wind vane I noticed that the rudder stops had been bent some time in the past. They are stainless steel but have no gussets to support the right angle.
I removed the stops and bought new stainless nuts and bolts as the original ones were showing signs of fatigue and corrosion.
With judicious use of a 4lb hammer I was able to straighten the starboard rudder stop so that it was a closer match to the port stop
It was then a simple task of refitting the stops with the new nuts and bolts to secure them.
