Keel nuts

[DOCKHAND]

The nuts on the keel studs are rusted and need to be replaced, has anyone done this on a 27' there are two 3/4" and five 5/8" studs. If the studs are made from 18-8 or 316 SS which would only have a torque of 43-45 ft-lb for the 5/8" and 92-96 for the 3/4". Does anyone know what the torque is to be on these or does someone know what material the threaded studs are made from? The studs and washer are in good shape.

I have an S2 27 as well, but it is a "Model B," built in 1987, hull #80. I have not done this job, but I am pretty sure that all my keel bolts are identical diameter. In 2008 when the boat was surveyed, the surveyor's recommendation was to replace the rusted ferric washers on the keelbolts, rebed them with 3M 4200, then re-torque the nuts to 65 ft-lbs. I haven't done that yet...

There are numerous pictures of the two different bilge configurations in the "Photo" section. Don't know how many total owners are members, but we would like to increase the number. Welcome.

model B

Thanks for the info on the torque, I haven't got the old ones off yet because there is not much of the nut left and unable to get them turned. As for the models I'm not familiar with model B, or sure which models they had.

I don't know what S2 called them, either, but I have always called mine a "Model B." These boats were part of the 1987 run; maybe a few in late '86.

The attached picture shows the changes to the interior, galley to starboard. The bilge configuration is different, too. The mast is deck stepped, with a compression post, which you can see in the photos.

I came acrosss a thread where a person listed that they worked for S2 and was giving information on what they did at S2. Do you who that may be?

Have you tried cleaning your keel bolt nuts with some WD-40 and a scotch brite pad? They might not be as bad off as you think. Also, the chances of the actual nut failing are probably infinitesimal, even if the part you see (the outside .5mm) looks rusty.
I think the article you speak of is the infamous "13 page document" from S2?
