The centerboard pendant on my 1983 O’Day 22 is frayed and needs to be replaced. I have put the boat on jacks and dropped the center board about 2 feet to find the connection. The pendant goes into a hole at bottom trailing edge and there is no apparent way to replace the pendant. There must be a side hole on the CB where the pendant is pulled out and slip knotted. It has been sealed over and I can’t find it. Has anybody done this? Does anybody have any idea of where to look? Is there a drawing available of the centerboard that shows the hole?
