Keel Bolts REPAIR Info. request.
Ahoy! Is there any one out there that has knowledge about the details involved with replacing the keel bolts (Rusted) on a Clipper Marine 23 foot sailboat?
I have inquired locally, with the yards and the prices range from arround six to eight hundred to 3 or 4 K. So, before commiting to putting her on the hard for a couple months and being grounded :(, I'm checking out doing it myself. Any suggestions or first hand knowledge that will assist in avoiding pit-falls will be greatly accepted.
Thanks, in advance for your reply.

Does it have a fixed or swing keel? Is the keel cast iron or lead or other?

Clipper Marine MK23, She is a twin keel boat, draws about 24 in of water. The bilge (What there is of it) is only about four to six inches deep. The nuts holding the keel bolts are almost rusted off. This boat was a recent "Gift". I have been fixer-up'n it for the past two months. Actually, the boat is in really good shape, after a good cleaning. However, I am concerned about the seaworthness of the vessel, what with the bolts in the bad condition they are. I'm just looking for comments from fo;ks that have tackled this type of problem. Thanks for your reply,

THANKS, for the info/web site. PROBLEM, Mine is a twin keel, not a swing keel. I can see that Mike had a fairly easy project with his boat. I am afraid my job will be much more complicated and probability four times the work. I'm still looking if you have anything as good as this for twin keels, fixed cast iron.

Nuts are often made of inferior metals, not the same stainless or bronze that keel bolts are. And, even with stainless nuts, sometimes plain steel washers are used with them.

So you might want to use a nut cracker, or a Dremel tool, to split off just one keel bolt NUT ONLY, from the center of one of your keels. Then use some rust remover to clean up the keel bolt, and see if the bolt itself is a problem--or just the nut.

If the nuts are the only problem, remove them and replace them one at a time. Check for the size of the nuts and make sure to retorque the new ones to the proper torque range. I'd apply a generous amount of threaed lock (LocTite) to lock and seal the threads, then apply a generous coat of something like beeswax over the whole, to waterproof it. (Easy to remove for inspection, sticks well, durable enough, cheap.)

hooyasailor, go to the following website for a discussion on replacing keel bolts in a cast iron keel on a Catalina 25. If your keels are cast iron, the process should be about the same. For more specific info, join the forum and ask the members. There's no charge and you don't have to own a Catalina to join.

And if you need a good cheap supply of beeswax, just go to the local home improvement store and buy a toilet wax ring.

Great Info - Thanks
This web is great. Good photos of the keel bolts, (Only wish mine looked that good) problem is mine are in really bad condition. One bolt is almost completely gone from rust. I've got a big job ahead, but thanks for your input, now I'll be letting you know when you should come over, so we can get started on replacing these rusted keel nuts. By the way,,, do you have a good heavy duty side grinder you can bring alone. see ya in a couple months, after I get her back into the water.

ps. Thanks to the other tips, "bees wax" werebeagle; hellosailor; pigslo,, OH YES,, We'll be expecting all you guys over for this tesk, it should-outta go quickly that way. You sure are a great gang to offer to help out this way.
