I have one of these sailing dinghies from the 70's. The centerboard pivots on a pivot mechanism and mine is broken. I'm looking for ideas on how to find a replacement part. Boston Whaler don't keep them nor does my local dealer and I have tried a couple of online vendors. I welcome any input.
Sounds like a broken lever, or part of the linkage. You may have to cut into the housing in order to replace or repair the mechanism.. I know I live in fear of that happening to mine!
Good luck, and keep us posted.
