Ches, I had good luck buying a new centerboard from Bob Eeg with lead filling. Alternatively, you could fabricate a new one yourself in the same way. If yours is anything like mine was, there's little chance of recovering it. It's built with two relatively thin shells and tiny steel punchings sandwiched between, that will keep expanding wider and wider as it rusts. By the time it's swollen it already has major structural failure, and should be literally "bursting at the seams" with rusty chunks. If you can't get the centerboard out in the first place, you will find photos of me dealing with this issue posted a few months back. I think it's worth it to construct a puller from the bottom, rather than try to push the board through from the top. I initially tried hammering a rod down through the top and damaged the inside of the centerboard trunk, which was difficult to repair working inside such a narrow area. Captain Jim Sadler (a fellow list member) designed an excellent puller that only took a few hours to construct, and removed the centerboard safely and easily.

My 81 15 has developed a stuck centerboard. It appears that the centerboard truck walls have developed the dreaded bulge. My board sticks up and while I can drive it down, I don't want to do this on a ongoing basis. I think maybe a 1/8" clearance might let it work again. I don't see trying to correct the bulge in the walls. I see either making a new board or sanding about a 1/8 to 3/16 off the width of the existing board. Has anyone done this? Is there enough fiberglass in the construction of the board that would withstand taking this much off? Thanks for any help. Ches Sugg M-15 "Mouse" (#153)
