I already searched for this and couldn't find anything on the nuts specifically. My bolts/studs are ss, but the nuts appear to be regular steel. About half are heavy rusted. They are covered with some goop. Not sure if this is factory or not. I ant to replace them one at a time and might even have to sirgically remove them. Any help or history would be great.

Sounds like a factory mistake, gooped by a P.O. as we often recommend here for the rusting mild steel bolts on the earlier cast iron keels. I'm assuming you have the encapsulated lead keel... (If you tap the side of it, it goes " ".) My '85 had that, and I believe they started using the lead in '84. My studs, nuts and washers were shiny stainless at least until I sold her in 2006.

I suspect yours is OK, especially as long as the nuts are gooped. But I'm not looking at them.

Yes, lead keel. Definitely ss studs. I wouldn't care except half thr nuts look like they are barely half there. I will probably replace with ss nuts. I think the torque spec was like 120ft lbs. I will wait a little for more replies.

I have photos of the bolts. I belive they are stainless. They are mostly non magnetic. However i feel like the orrigional sealant, smells like thickened resin must have failed and the stainless started to rust. I would appreciate any info on this. I want to clean up the bolts and reseal them, any recommendations on what type of sealant would be appreciated.

It could be that your boat was caught up in the transition period from steel to SS. Looks like you got the SS studs but might have got the steel nuts that Catalina had to use up before using the new SS nuts.

That first photo shows what looks like a little rust, but stainless can discolor like that, and cause discoloration around it. And there are different grades of stainless (304, 316, etc.). They all require some oxygen to stay shiny looking, so covering it with resin is likely to create that look. Your 18:10 photo looks suspicious--what do you get from a magnet on that nut? The others look like about what I'd expect. (I don't recall mine being covered with anything.)

Dave, Passage’s nuts are still nice and shiny. There’s no goop on them and no rust. I occasionally get at most a pint of water in the bilge after a heavy rain but that hasn’t created anything even vaguely similar to the 18:10:12 photo.

I can’t believe we’re discussing Passage’s nuts!

They are slightly magnetic. Not like a mild steel, and not like 316ss. I suspect they are 304 and we're bedded with thickened resin witch the extra was used to cover the studs. The lack of o2 caused all the staining. I am going to clean them up and keep them open and keep an eye on them

I have water getting into the bilge from the deck fittings which I will of course take care in my project; but I just do not get it why compartments below seats are actually "connected" to the bilge; is it a design fault? am I missing something there? If I just fiberglass, that water (from the deck) will not make it to the bilge and will remain underseat with no effect on keel bolts, am I right? I just saw a picture from another member with exactly same layout as mine (picture below)
