One thing you might consider if you are worried about crevice corrosion is replacing the keel bolts with something other than stainless (assuming they are stainless now). The feasibility of this would depend on how the existing bolts are attached to the keel -- are they "j" bolts that were put in the keel when it was cast (i.e., bent into a j shape) or are there pockets in the keel and the bolts are basically a rod with threads and nuts at each end? If the latter, it is possible to replace them. This is actually what I am doing on my boat right now (the keel is coming off this week). We are going to use silicon bronze for replacement bolts, which avoids the crevice corrosion issue. More expensive than stainless, but more durable for this application. There are other options than silicon bronze as well.
