I have a 1993 Hunter. I have to replace the line that raises the centerboard. The manual is not very helpful. It looks like the whole assembly is held in the well by a single bolt. I assume one must pull the boat and get it on a sling lift to do this. Do you just drop it down and then thread the line down thru the tube by the mast support post? I also want to replace the pin on which the centerboard pivots at the same time. Can the pin be ordered from Hunter or does one have to fabricate it?Also I need a new mast foot. the hinge casting has broken off making it tricky to raise the mast. Hunter referred me to Z Spar but they don't have anything that looks right. Any ideas?
