O'day 25 CB Question

[Ward H]

When I bought our 25 in the fall of 2012 the CB was stuck up. In the spring I had the yard drop the board and I sanded off paint and took a bit of gel coat off to thin it a bit. When the yard reinstalled the board it was free moving in the trunk.
The board moved up and down fine all summer.
Then a couple of weeks before a sailing vacation in Oct it stuck in the up position again. The yard did a short haul and unstuck the board as the Admiral would not sail in a broken boat.

What they found was that the pendant had worn a groove in the opening where it exited the pendant tube into the CB trunk. When I had pulled up the board the thicker part just below the eye splice had stuck in the groove.
For the vacation I just left the board down 6" or so.

Has anyone run into this issue and any ideas how to fix it?

Ward, you might want to give Rudy at D&R a call. He might have some insight. I know that for the 222, Joe (Trinkka) talked about a sheave that mounts up in the trunk, and in one instance that sheave was missing, leading to prematurely worn pendants. Also, you could probably eventually replace your pendant with line that's thinner - it's surely less desirable from a hand comfort standpoint, while raising the board, but for sure it's a last resort you can keep in your back pocket...

You seem to be missing the small pulley that's inside the top rear of the center board trunk. My 25 has one. I don't know how you can repalce it You would have to cut into the interior floor of the cabin to reach the top rear of the centerboard trunk. You may have to find an alternate solution.

Maybe the yard could glass a small stainless round pin in to protect the tube from getting groved?

Sorry that should be grooved

You may be right. I was under the impression from previous readings there should be a sheave for the line to run over.
The yard thought the only way to fix it would be to do what you suggest.
The pendant is in very good shape and shows no sign of ware so I am wondering if it was replaced sometime in the past couple of years and the eye splice was poorly done so it is thicker and longer than stock? the sheave could still be there, just the eye splice or the pendant near the splice is too thick for too long a distance?

My options appear to be:
1. Install a new pendant with one size smaller line and be sure eye splice is short and tight. (Thanks Brian S for this idea)
2. Have boat raised, confirm no sheave present. Open the trunk from the top and attempt some sort of repair.
3. Do nothing and leave the board down a bit.

On the 1980 there is a step over a compartment. In that compartment are the two ends of the shafts the pendant line goes through connected by a rubber hose. I am thinking of pulling off that hose and try to get a look from there. Maybe a spy camera threaded down the opening?

Since there is no sign of wear on the pendant, I am thinking option 1 is the way to go.

The pin is a good idea.
If the line is wearing a groove in the tube, I might be able to get a SS tube that would fit the ID of the tube. Then have it cut 1/3 length wise and roll the end. Then it might be possible to push it in from the top and glass it in.

Hoping it does not come to that.

Brian, I plan to call Rudy next week. Thanks

Our original pendant was wire spliced to rope. We replaced ours with all rope. Our board gets sticky when it's more than 90% retracted, so we just marked the pendant so we never lift the board more than 90%. No ill effects in the past 3 years. During the off season when the boat is hauled we just rest it on the front and rear edges of the keel and let the board hang down to be painted.

My boat doesn't have a block. I don't know what year Oday made the change.

Well, if your 1983 25 doesn't have a sheave, either it was lost at some point, or O'DAY stopped installing them at some point (assuming that they ever did put one in the 25?) because 1983 was the last year for the 25 since the 26 was introduced in the Fall of 1983 as a 1984 model ,replacing the 25. The 26 did have that sheave from what I've heard.

My boat had the wire to rope pendant and the wire wore a groove deep into the glass. I bought a all rope pendant from D and R and installed it. I had no problem with lowering the board until late last season when I tried to lower it it would not go down. I chocked it up to growth on the board etc. but now that I read these posts, I wonder if the pendant got stuck in the groove when I last pulled it up. when i pulled the boat out at season end I saw no growth on the hull. HMMMM I wonder.

Talked to Rudy this afternoon. He said that the 25 never had a sheave, the smaller boats did.
I asked if he has heard before about the pendant wearing a groove in the side of the exit tube. He said it was more likely some crap or barnacles were causing the board to stick in the up position.
I might try a next size smaller line for the pendant like Brian suggested.
