M-24 Centerboard
here's my 2 cents worth on the M-24 centerboardI lost my c-board on the delivery cruise from the previous owners dock to my home boat yard. The board had much damage due to neglect and a lifetime in salt water. The bronze mounting blocks were worn to a degree that allowed the board to twist and bind in the trunk. The trunk itself was full of barnacles. The grooved top edge was broken and not guiding the ss cable properly. The edge of the c-board surrounding the pivot pin was damaged and blew out completely when we had a little rock and roll while trying to dock in a quall. The cable was so frayed that it could not support the direct weight of the board and snapped and sank at that dock. When I hauled the boat for work, the board was gone. I recovered it at the dock and made the repairs.My advice is to elevate the boat enough to remove the retaining blocks, lower the board and disconnect the cable. Pull the pennant from the inside and trace the entire system, checking and repairing all the components, including the c-board itself and the blocks and pins. Obviously the problem you speak of could be caused by several things, and putting a band-aid on one thing invites the next thing to fail.You can reach me at mcmacduck@aol.com if you need any more info.
