Re: Rusty Keel Bolts - How bad is it?

hello Mathieu, Thanks for the info

A couple of questions...

In the boat I only readily see 8 bolts, but they say there are 11?
Did you change all of them?

I have some weeping water coming through...did you have that?

Did you change them while the boat was in water or on land?

Did you use a socket and breaker bar, or an impact wrench to remove? If an impact wrench was used, any particular model?

I can add some pics of the bolts...I will get that this weekend...its currently in water.

This was my uncles boat, he originally obtained in France (1985)...I inherited it and the keel bolts are the last things I have not touched in it as far as repair! Trying to make it last another 30 years!

Thank you
Bertrand

Re: Rusty Keel Bolts - How bad is it?

I did pulled one out and all threads are like new. We had a hard time with two of them, one was freaking torqued, and the others so rusty that it was impossible to have a good grip. I managed to grind it a little bit and fit a different socket on it.. I did not ordered from beneteau France because they don't stock them any more, but the boatyard finally got me a good price for same spec bolts...

Thanks to all of you, otherwise I might had agreed to remove the mast and separate de keel.

Cheers!

Re: I just replaced my Beneteau First 345 Keel Bolts

Hi, i am interested in your experience changing these keel bolts. I have a 1985 beneteau 345 first, and the original keel bolts....they are rusted and appear to be "weeping" water. thinking time to change and seal...from the outside, the last time short hauled..keel joint looked fine...These bolts have been looking and acting this way for years.

I see you used an impact wrench to loosen...how did the bolts on your boat look? Bad? were they dry or also somewhat wet? leaking? etc.?

Thanks,
Bert

Re: Rusty Keel Bolts - How bad is it?

If its leaking at all the only reliable way to seal it is to drop the keel. Once you get the nuts off or bolts out it's easy, just brace the keel up so it doesn't tip over and have the yard lift the hull off. If it looks like you'll have to work on the keel make sure they leave you enough room to do that.
My yard didn't even charge me for the extra lift time.

The Beneteau keel bolt replacement file is reproduced in its entirety in post #22 at (click on) Beneteau Keel Bolt Replacement Discussion. Unless you find that your keel bolts show signs of wetness once you've pulled one, there is no need to "drop the keel". In fact, the bolts can be replaced, one at a time (working in a star pattern), while the yacht is in the water.

FWIW...

Re: Rusty Keel Bolts - How bad is it?

When I pulled the galvanized bolts out of my Columbia 36 the forward most one was rusted right through below the surface. Didn't appear to be connected at all. The other eight looked almost new below the surface but very rusty on top where bilge water had gotten to them. I replaced them all and added an extra where the single bolt had rusted out, there's now two side by side. Since the joint was leaking I also dropped the keel to rebed. We're now waiting for a good day to set the hull back on the keel.

A couple of wacks with a maul on the top of the bolts to dislodge the larger rust and little work with a wire brush chucked into your drill will clean them up well enough for you to loosen and pull the bolts. That can be done one-bolt-at-a-time in the water, the process recommended by Beneteau, or, shoreside during a haul-out if you're the nervous type. If you will PM me with your email address I will forward copies of Beneteau's procedures for replacing the bolts. Once the new bolts are in place, they should be thoroughly coated with a moisture barrier as described in their literature but it's not a big deal. You'll do fine.

FWIW...
