I recently bought a 1995 Sea Nymph FM 161. I've been going over everything on the boat, and I'm wondering what the secret is to maintaining the pedestal seat posts. The pedestals are all hard to remove from the bases (although they all come out.....just too much effort is required!). I can see where the former owner put a pipe wrench on the posts to get them out. Should they be cleaned up and lubed with silicone, or is there some other secret to this?
