First time on this web site--any help is appreciated. Line to centerboard is frayed topside and must be replaced. Never used c/b and don't know how line is connected. Topside is an eye splice. Also don't know the length of line required--nothing in manuals. Would like to solve these mysteries before I have boat hauled. Also, need a replacement for bow navigation light--mishap with a dock!! Are 1984 O'Day 30 parts available anywhere? Finally, Universal diesel M-18 is missing the grease cup--replacement part avaialble?
