M_Boats: Trunk Disease

Finally got around to looking at the keel on my (’84) M17 and it has the disease—the centerboard trunk is separated all the way around the lip. I can have it hoisted up next week and see if the centerboard operates. If not…well, let’s worry about that later. In the mean time I’d like to know if the two centerboard pins are sleeved where they go through the stub keel, and if not, how to make them seal inside the slot.
