Hello all, I'm new here, it's my first post... Here goes... I had a survey done yesterday on my 1978 C30 (my first boat ever) and I was told the keel bolts are fine but I was recommended to replace the nuts and washers for good measure since there is some corrosion and they are pretty old (who knows how old but they don't look like the originals). Question: Is it a good or bad idea to use nylock nuts as the keel bolt nuts? I bought 316 SS nylock nuts and regular washers that match the sizes of the replacement kit on Catalina Direct but on second thought I was wondering if water from the bilge gets trapped between the nylon and the nut it could cause the new nut to corrode prematurely. Yes or no? I haven't installed them yet, still learning that procedure, but I want the right nut and I haven't heard of anyone using nylock nuts on their keel bolts. It seems like there isn't much space for water to be trapped in there but I want to do the right thing. You all know more than I do and I appreciate your comments and any advice you have to offer. Cheers!
