Centerboard wedge setup
Rad, What you just described is pretty much what you and I have in our O'Day sailboats. There is also a smaller slot where the pendant line comes in from the top back, and through a small sheave and down to the trailing edge of your centerboard. As far as I know, there isn't anything in my O'Day Owner's Manual on these wedges and the fiber pin that the board swivels on. After you remove these wedges, with whatever you intend on using, and I used a fillet knife, you'll need to clean the caulking out of wedge slots for the centerboard pin to drop down through them. The hardest thing that you may encounter is trying to remove the four Phillips head machine bolts that hold the two plates to the keel. I had to use an impact screwdriver on two that were stubborn. I didn't hit it too hard for fear of breaking the bolts. Stainless Steel bolts break very easy. I used Never-Seize on the bolts when I reinstalled the centerboard. Outside of that, you shouldn't have a problem. There are also two wood screws that go into the bottom of these wedges that need to be removed. Mine were missing and I had to reconstruct my wedges with epoxy before I reinstalled my centerboard the other day. Those wedges could be made very easy. They're so simple. When I reinstalled my centerboard, I tied a snatch block in the cockpit to my traveler and ran the pendant line through it with longer line tied to it so that I could pull my centerboard up while under the keel. I was able to tie it off to one of my boat stands. I also ran a line over my cabin and under the keel to keep the centerboard from falling on me while I was working on the wedges. I had cut a stick to wedge the centerboard all the way up and hold it there from the ground. My son had come down my house last week with a heavy duty industrial power washer, and this is what I used for cleaning the inside of the centerboard slot. We later used it to wash the Teak and believe me, nothing cleans Teak like a heavy duty power washer if you go with the wood grain. I was able to get two coats of Super Ship Bottom ablative paint in the slot with a small roller on a stick. The whole job worked out great for me, and I'm glad that I did it.Joe
