Haul out time will soon be on us and I have added "Check the Rudder" to my job jar, but I don't really know what I should be looking for.For example, how does one when check or test the rudder bearings/bushings? Or the rudder stock? What other things should be checked? If the bearings/bushings need to be replaced, where does one purchase them?Is this a "do it yourself" job, or should I call in an "expert"? Our boat is a Hunter 430.Suggestions, comments would be greatly appreciated.Thanks,Peter MilneS/V Blue Heron
