1983 C&C 29 Mk11 Keel Bolt Question
 
Hello, I'm a new member, & I just purchased a (1983) C&C 29 MK11 sailboat, I have to re-torque the keel bolts on this boat prior to launching in spring 2012. At present I can't get to the boat, but I would like to know from another knowledgable owner, as to how many keel bolts there are on this boat, also what size of bolts/nuts they are & finally, what is the torque value of these bolts, all specific information on this exact boat would be most appreciated.

Have you posted the question here?

C&C Yachts - C&C Photo Album & Resource Center

Look down the left hand meny for "Do it Yourself" then the menu after that for Keel bolt torque specs.. you will have to find out the bolt sizes, though. That info may well be here somewhere too.

Hello Faster, there's not much of the specific help I'm looking for there, I did see that link, but it covers a variety of boats & not specific to my needs, thanks anyhow. Ed

Actually it gives the torque specs (and wrench sizes) for all models, depending on keel bolt size.. as I mentioned you'll have to find out what size your bolts are somehow - but the torque requirements will be based on keel bolt diameter and material, not boat model or brand.

If you can obtain the manual for your boat from that it will have the bolt torque specs. We have them in our C&C 35 manual. You can download the manual from the C&C owners site which I woulkd recommend joining anyway. Also for technical information call South Shore yachts as they have many of the older C&C parts in stock and work on them extensively as their are quite a few on the Great Lakes.

On my C&C30 Mk 1 I believe there are 4 keel bolts (maybe 5). What I'm sure of is they are 1" diameter and are torqued to 350 ft lbs.
To actually torque them to specs, you'll need a deep well 1-1/2" socket (if the bolts are 1") and a torque multiplier or one heluva big torque wrench. I actually bought a torque multiplier and the deep well socket to allow use of my 1/2" torque wrench with 3/4" adapters to fit the socket and torque multiplier. It cost me about $175 for the tools.
If I had it to do over again, I'd let the yard do it, although I don't think they had the tools anyway.
They really needed it. They were just beyond hand tight and the C&C smile required yearly patching. Since torquing to specs, the smile has not reappeared.

I have a C&C 29-II (85). There are 5 total keel bolts with 2 different sizes of bolts as I recall. The 5th one is in the mast step. Also it is very important that the drain holes in the hidden small bilge under the mast step be open so that any residual water can drain into the regular bilge. There should be two 1/8' holes in the forward wall of your bilge. Unfortunately I can't recall the diameters of bolts and my boat is under wraps for the winter.

Check around and you can probably rent a +size torque ratchet and sockets. I got them at my local Ace hardware rental.

The info for all older C&C models is on the CNCphotoalmum.com The torque fl/lbs is listed by bolt/stud size.

KEEL BOLT TORQUE SPECIFICATIONS
MODEL SIZE BOLT DIAMETER FOOT POUNDS SOCKET NUT
MEGA ONLY 3/4" 90 1-1/8"
C&C 40 1-1/4" 450 1-7/8"
ALL OTHER 1/2" 80 3/4"
MODELS 3/4" 250 1-1/8"
1" 350 1-1/2"

Thank you MSMITH10, you're the closest to answering my specific question, although it's not the 29.MK11. I was hoping someone would have the actual manual on the (1983) C&C 29 MK11 which would give me the exact information I'm looking for :-
How many bolts
What size bolts, including nut size
The speficic torque for those bolts
I may have to finish up buying the manual to get the specific acurate information I'm looking for. Thanks everyone else for replying, Ed

Capt Ed I have the actual C&C 29-11 manual. Unfortunately it is not that good when it comes to details regarding the keel boats. I will send you a scan of the keel boat diagram when I'm back to my office at home late today. It does not give you any details on the keel boat size or specs. The torque figure cited in an earlier post are accurate. I'm guessing that the 2 sizes of bolts are 3/4" and 1". You will probably have to measure your to be sure. I had my fiberglass retorqued my bolts when he faired the keel. I do know you will need a 3/4" ratchet, breaker bar, and a pretty big torque wrench to do the job. I do have a complete service manual for the Yanmar 2GMf if you need it. Let me know. Here is another site with some more info on the boat. C&C 29 Mark II Resource Site
