Has anyone ever replaced the small wheel that is part of the system to raise and lower the keel? I have a swing keel and noticed last fall when I pulled the boat that a stainless wheel was hanging from the vectran line that raises and lowers the keel. The wheel should be located in the keel trunk under the boat. When I had the boated lifted at the yard this spring to re-attach the wheel it appeared the two bolts that held it in place had striped the threads in the hull. The mechanic at the yard suggested I drill through the hull in order to install a back plate. Since that would penetrate the water ballast tank I passed and instead drilled a hole in the end of the keel and attached the vectran line there. This should get me through this year but I would rather fix it properly. Any ideas?

I searched the old posts, because I thought I'd seen a picture of this, but it is too far away to tell whether they are studs embedded in the fiberglass or a metal plate glassed in with threaded holes. Your repair will likely be dictated by this finding. (your post seems to support Pauls recollection.)

Here is a quote from an old post by Paul of Joint decision-

"Do you mean the 'turning ball' or are you referring to the 'lead block' that is screwed into the top of the keel well above the point where the line attaches to the centerboard? I'm assuming you refer to the 'lead block'.

I believe that the wheel is held in place with a rivet! So if the wheel has come out, then you should probably replace the whole lead block rather than just put a bolt in place which will most certainly wear rapidly. (assuming you operate the centerboard )

You should find that the lead block is bolted to a metal plate with 1/4" bolts.

Any indication what caused this???

You will need to get the boat out of the water and home. Then follow directions on this site to lift the bow and drop the keel (sounds bad, but it's a 1 hour procedure tops)

I don't remember if it was studs or tapped holes, but according to Paul's recollection a metal plate is glassed in your hull. I would guess you could attempt first to overdrill and tap the hole with a good quality tap. I say good quality, because nothing is more frustrating than having a harbor freight cheapy break off in the hole. I would pay significantly to avoid this... your mileage may vary. I own the HF set, (with several broken taps) but I'd spring for a nice single tap for that job.

Next try would be to measure the depth of the stripped holes and, with depth stopped drill bit, drill adjacent (for or aft by 1/2") holes the proper size to tap a fresh set of the original size holes.

Next try would be epoxying a set of stainless allthread studs in the stripped holes slightly undersize and attaching it with locknuts.

Just a few ideas.... hope any of this helps. It sounds like you should only be out of service one long day.

It is the lead block that came loose. Both 1/4 inch bolts are still attached. The yard mechanic thought they were bolted in the fiberglass. I could'nt imagine doing that without some backing. Having a metal plate glassed in makes more sense. I think I'll try tapping the holes in the fall since the boat is in the water for the season. I alway like to have a project to look forward to. Thanks Essen.

Essen, I looked through the website but couldn't find the instructions for lifting the bow, as you described. Could you tell me where to find it?

I didn't think the 250 WB has a keel. They have a <i>centerboard</i> to provide lateral resistance. The water ballast takes the place of the weight of a keel.
