When I first got my '84 C-27 10 years ago, I found that the keelboat nuts were 
eaten halfway through, and plier tight. Happily, the boat had not developed the 
"smile". I replaced the nuts with new stainless (the original  nuts and bolts 
in my boat were 5/8" stainless). I have been able to work these nuts down to 60 
ft. lb. As I noticed that the bilge pump hose could not suck the water level 
below about 1 1/2 inches, I installed a strainer box on the end of the hose and 
secured it to the bottom of the sump. The pump can now draw the water level 
down to 1/8". 

This season, realizing that I had 22 years under the keel, I decided as a 
precaution to purchase Catalina Direct's lag keelbolt kit, plus 3 extra bolts, 
for a total of 8. I believe that nothing succeeds like overkill. I installed 
the first pair of bolts 10" ahead of the first existing pair, and the other 3 
pairs equally between the existing two pairs. I used a 1/2" drill to turn the 
bit. I found that the "tef gel" product that came with the kit made the bolt so 
sticky that I couldn't draw it all the way down with a 3' bar on the wrench, so 
I used Permatex anti-seize compound. That's that silver stuff that's hard to 
get off your fingers, but it lubricates, and helps keep dissimilar metals from 
corroding together. Slow going, though. Takes a lot of time and torque to run 
those bolts down into the lead.

My boat should now last forever - ha!

        Listees,
             After a, ahem, hard grounding, my Catalina smile has reappeared 
(last seen 6-7 years ago) — not badly, but a thin line at the keel joint is 
visible on one side.  The boatyard service manager has recommended 
re-torque-ing the keel bolts.  Naturally, the yard will do the job for a fee, 
though I don't have a quote.  I'm concerned about these 30 yr-old bolts 
breaking off under 60+ ft-lbs of torque.
             Any of you who have done this yourselves:
        1. How did you clean off the accumulated rust (They were rusty, right)?
        2. Were you able to budge the nuts?
        3. Did you remove them —one at a time, of course — and clean the 
threads?
        4. Did you replace with stainless nuts?
        5. What torque?

             For those who have installed SS Lag Bolts in your keel.
        1. Did you buy the $279.95 kit from Catalina Direct?  (5 bolts, 1 drill 
bit, washers)
        2. What size is the drill bit?
        3. Did drilling require a rotary hammer type drill, or just a powerful 
standard drill?

             I have source of SS 1/2" x 8" SS lag bolts @ 14.95 each.  Specs 
say 18-8 stainless; no mention of 316.  Thoughts on using these?

             Thanks for comments on your experience.

        Fair Winds,
