This web page on replacining a Pearson 26 keel bolts looks similar to the older Santana cast iron keel bolts: http://dan.pfeiffer.net/p26/keel.htm

:: I put new bolts on mine a few years ago when I had it
:: out at the Berkeley Marine Center. I told the boatyard
:: what I planned to do, so when they hauled it they also
:: blocked the keel so it wouldn't tip when the bolts were
:: out. In my case, removing the nuts inside the boat was
:: pretty easy, and then we just knocked the bolts
:: (actually flathead machine screws) out with a hammer and
:: replaced them with stainless steel that I got from Steve
:: Seal. Once they were out I had the boatyard raise the
:: boat a few inches and the keel came right out of the
:: cavity it is set into. We cleaned out the area and
:: replaced the screws using 5200 as a sealant after the
:: boat was lowered back on to the keel. I understand that
:: will make it extremely difficult to pull the screws out
:: again, but it probably won't be necessary. I still get
:: the rusting at the hull joint which is endemic for these
:: boats. I understand there is a new epoxy that one can
:: use in the joint that is extremely sticky and will keep
:: the keel from rusting. I strongly suggest that you
:: replace the bolts with stainless, since rumor has it a
:: few keels have fallen off due to bolt failure.
