O'day 25 c/b pin wedge seal

[gene]

Would someone please explain to me how the sealant/caulking seals the wedge area. Where would water leak into? I don't understand the engineering/design here. The wedges hold the pin but they don't really wedge anything unless the boat is upside down. The stainless plates hold the wedges in. The screws hold the plates. What needs waterproofing? I thought after I took it all apart I would have a better understanding but nope, not me. I put sealant where I removed the old but can't understand zactly what I'm doin'. thanx, gene

I'm gonn'a be in the same boat.

This fall I would like to remove the centerboard in my 222, somebody bit a three inch chunk out of the trailing edge of mine. This winter I'd like to dry it out and do the penetrating epoxy thing and scarf in anew section.Gene, when I read your post I just know that I will also ask the same questions.. SOMEONE PLEASE COMMENT,,, Been there anyone? I also can't picture what the wedges do and what the caulk does either.

I think .....

I have an O'Day 23 and a few years ago removed the swing keel. The wedges hold the plastic pin which acts as a hinge or shaft for the swing keel.The wedges are held vertically by the stainless steel plates.The sealant is, I think, more of an adhesive or glue to hold the wedges against the side of the fixed keel so that they do not move around. If you do not use the "sealant" then the lateral movement of the wegdes is limited by the swing keel itself.I do not have a cross section of the trunk of the keel but it did not seem to me that the pin went into any kind of mating geometry inside the trunk of the fixed keel. The pin just sits on top of the wedges.So I think the sealant is a temporay adhesive which holds the wedges in place. This helds remove or reduce the stress from the screws which hold the stainless stell plate in place and also stops the wedges from moving when the swing keel is dropped. When I removed mine and rebuilt it I used 4200 when I put it back in. I re-did it a year later when I re-centered the swing keel. When you re-install use some wedges (I used some shingles I had lying around) to centre the swing keel in the slot so that it can move freely.Finally a word of caution - on the 23 the swing keel weighs more than 60 lbs so make sure you support it well as you get under it to tighten those screws holding the SS plates.That's my opinion ..... If you want the real reason ask Rudy at D&R Marine - I'm sure he will know. (508)644-3001CheersJames

James is correct

James is right on with his description of installation/function of the 23' centerboard. It's a reasonable easy job when on land, with the proper equipment, and with a little planning. CVP

222 and the centerboard........

OK while my 222 was lifted in the sling to be launched I went under to inspect the centerboard and found they are not much. It is a piece of plywood that is beveled both fore and aft and covered with I think roving woven fiberglass.. Not very heavy at all.. It is long 4' and narrow maybe 18" wide. It lifted up into the shoal keel very easy. Sounds like the 23's are very similar. there is a plate on each side of the the centerboard with three screws holding it in. I've not had it apart yet but plan on removing the whole assembly this fall at haul-out.
