Just bought this Capri 25. The keel bolts are fine. The nuts are rusty...not stainless.
Is there a technique to remove one by one? What torque for the new nuts?

Congrats on buying a Capri 25.

This is from Kent Nelson at Catalina.
"The keel torque for the 1/2" bolts should be 39 ft-lbs with the boat on the hard and the keel supported."

If you are just looking to replace the nuts and washers I would give one a good soaking with PB Blaster and let it set overnight to verify whether the nut will release or not. I have had good luck with this product removing corroded hardware. By the way, stainless can rust. Depends on the grade of stainless used.
Whatever process you follow your biggest fear would be twisting off a stud so approach it carefully. If the torque setting is 39 lbs., and the stud is corroded inside the nut, it will take less then 39 lbs. to break the stud. You might also use a nut splitter which may be more safe then twisting off the nut but again it will depend on the condition of the studs threads inside the nut if it is reusable.

If you have viable thread above the nuts, use a nut splitter or if that worries you, put a cap over the rusted nut that is held in place by an additional nut. Something like a stack of large washers that fit around the rusted nut with a smaller washer that is held in place by the additional nut.

I agree with all the info. that you have received.
My Capri came to me with SS nuts and flat washers, I added SS
lock washers one at a time so as not to free up the keel entirely and re-torqued to 39 lbs. I found outthat after a coulpe of years or so without the lock washers the nutswould loosen just a tad, 2 to 4 lbs.

An aside--- always take a small magnet with you whenever you go to
purchase ANYTHING out of stainless. Low grade ss will be attracted
to the magnet. PASS on anything that fails this easy test.

Checking with a magnet is excellent advice!
