DIY Mac 21 Keel job
Earlier this year, I dropped the 450# cast iron keel on my Mac 21 and re-worked it. I installed a new winch, new SS keel cable/bolt and a new pivot bolt. To do it, I simply put my car jack underneath it and let it drop down onto the MacGregor trailer. So the keel was only 2/3 of the way down, resting on the trailer's crossmembers. I simply did not have the set-up to completely remove it.From there I replaced the pivot bolt/cable/etc. and then jacked it right back up. Amazingly, the holes aligned and I re-chaulked the washers/nuts on the interior. While the keel was down, I cleaned it up, primed it and re-painted it.Good luck,Kevin
