Paul,Hi! This is my first boat and my first time on this site. I have to repair the centerboard and do not have a clue on how it should come off. I know that there are some experts that have done this and can enlighten me.
Thanks
Paul
Paul,
Supposedly, there's tons of info in the archives of this forum on centerboard removal, but do you think that I could find it? I think that I've posted a good percentage of this info to different guys through the years. Oh well, that's the way it goes I guess.
The centerboard on your O'Day 25 needs to come out through the bottom of the keel. It has the same type of configuration as my O'Day 222 and the O'Day 26. That means that you're going to need to get the boat in a position where the keel is exposed. I was able to use large wood blocks, sailboat stands, and a hydraulic jack when I removed my centerboard. Looking at the keel from underneath; you'll see two steel plates which are held on by four Phillips head machine bolts. You'll see two triangular wedges that fit into a rabbet groove on each side of the keel slot, on top of these plates. There are two wood screws that go through these plates and into the bottom of these wedges, but what really holds these wedges in place is polysulfide adhesive caulking. The wedges in turn, are what is used to support the 1" solid fiber pivot pin for your centerboard. To remove the centerboard,-- remove the plates. Spray with WD-40. I would use a good cordless impact drill with a Phillips bit just in case the bolts are stubborn. To remove the fiberglass wedges from the slots,--I used a fish fillet knife to cut the caulking behind the wedges, and a 1" metal putty knife. If you damage the wedges, they can be fixed with a fiberglass repair kit such as the West System packets and filler. Remove the wedges, clean the grooves out, and that whole board along with the pivot pin will drop right down. When I removed my board a couple of years ago, I steam cleaned the centerboard slot and painted the inside with two coats of ablative paint except for the rabbet grooves. Be advised that there is a small sheave way up inside the centerboard slot in which the pendant line goes through. Take a flashlight and check it out. Good Luck, Paul.

It was my pleasure RAD. I think that they were all set up the same way too, and if you think about it, it was a very ingenious idea, whoever came up with it. Rudy tried to explain it to me one day years ago when I was in his store talking to him about it, and I came away in a deeper fog than I was in before I asked him. He told me, "Ah, you never want to take that thing out of there unless you really have to Joe!" And, "It's a real job trying to get that thing back in there after you get it out." I learned what really made that thing tick from someone on this forum. He showed pictures and sketches of it and finally the fog started to roll away and I too said to myself, "So that's how it works!" As far as being a tough job goes, nothing could be further from the truth. Not that he lied to me. I believe that he probably had a tough time doing the one that he did, but I didn't. The toughest problem in doing that job is getting the boat high enough to be able to get under the keel and work on it. If you can get four bolts out that hold the plates, you've got it knocked. You know that once you get the plates off, wedges out, and rabbets cleaned of caulking, that board is going to fall right down out of there,--on your head if you're not careful! I took two straight lines and ran them through my hand rails on top of the cabin and under the keel. I tied a Bowline on one end of both lines and ran the other end of each rope through the Bowlines with a round turn, and took up the slack right up against the under side of the keel, and tied a slipped half hitch on each line. I was able to let the two lines off easy while under the keel, and she came right down as slick as s#%$. Getting the board back in was just as simple. You just need to plan it out and think ahead.Thanks for the pictures Joe, I have archived them with my ODay pics cause I'm sure my board on the 32 is installed the same way...I've looked at my installation and now that you've played show and tell I've just had a ah-ha moment.
And I believe someone last week was asking about the exact same question and same model boat
I think that they all have a tendency to swing or rock sideways and make noise when there is no pressure on them. I know, mine does. I always put my board up before I come to anchor and it stays up until I'm ready to sail out. I don't think that there is any way to tighten the board. It's probably a good idea to always keep the board up when you're not using it anyway. The constant rocking and swinging could possibly wear on the pin or elongate the hole in the centerboard. When I checked my pin and board a couple of years ago, I found very little wear if any.I have to keep my centerboard up on my O'Day 25cb while at anchor as it is loose in the slot. Has anyone tried to tighten up the centerboard in the slot so it doesn't bang back and forth? Was it worth the effort?
If you can get at the board without pulling it out, I don't see why you can't make the minor repairs to the bottom of the board. Pulling the centerboard out is something that you may want to do just once in order to check the pin and clean up and paint the inside slot along with the board itself. Other than that if you can get away without removing it, you're better off. For a boat of that size and weight, you're better off supporting it in a sling than supporting it the way I support my 222.So after reading that, there is no reason me to pull the board out......the small minor repairs that I get are on the corner from hitting bottom while sailing and I've made some quick West System repairs B-4 launching while hanging in the straps overnight
Mike, many oday owners make an annual pilgrimage to Trinkka's. Those that can't at least turn toward the northeast three times a day to give thanks!Joe has just shown again why he is an Oday centerboard guru. One little additional bit of info. If you need spare parts, you can get replacements from Rudy at D&R Marine. Here is the link:

I just caught that one Keith!:dance: I have to honestly admit that the guy who drew out the sketch of the centerboard components along with the picture of the actual parts shown on a plaque, really deserves the full credit. After I was able to understand the way it was put together, it cleared up a lot of confusion for me. Here's the pics, and many thanks to the guy who posted it on this forum.Mike, many oday owners make an annual pilgrimage to Trinkka's.

Ahoy there, Ed!Joe,
There is an error in the pictures. There is no centerboard. Are these pictures from the guy in Florida who lost his centerboard?

There is enough space in front of and in back of the keel slot to block it. If you can block it there you shouldn't have any trouble accessing the CB and the slot- provided it's blocked high enough; about 18".Hey I have a question that is related that might also help you out paul..My centerboard line that pulls it up and down is still intact and functional but I would still like to change it for next spring just to play it on the safe side..I am thinking that my only opportunity to change it would be when the boat is getting lifted out of the water and its on the lift..is there any other way to change it? Will i be able to just drop the board when its on the lift and look in the keel to see where the line connects to the cb? take that line off and put the new one on and snake it up to the slot that goes into the cockpit?How easy is this to do?I know that the longer I have the boat on the lift the more the yard is going to charge so I would like to do it semi quickly..would love to be able to do it once it gets put on the stands but then the keel is resting on wood blocks and would prevent me from dropping the board or looking in the keel slot...am I missing something?
You can certainly reuse your shackle, but if you've never replaced it, odds are that it has been sitting in salt water for years. Rudy's price for the line is quite good, and you won't be saving a lot of dollars by reusing the piece. I highiy recommend just replacing the whole thing. And if you have a carabiner-type fitting in addition to the shackle, I would simply do without it. I had one of those set-ups too (splice to carabiner to shackle to centerboard) and decided to eliminate a potential source of failure by going with a splice to shackle to centerboard arrangement. Also, by taking the carabiner out of the equation, you remove a potential fitting that can (and occasionally did on my boat) stick in the centerboard trunk.I just looked at the d &r marine website-glad that I could get most replacement parts...I was looking at the cb pendant...Im assuming I do not need to buy this because I already have the metal piece attached to the cb..all I have to do is buy an identical spliced line and attach the spliced end to that metal looking carabiner like clip that attaches to the cb..is that right
