In the process of powerwashing my boat this morning, my friend discovered that the pin that holds the centerboard in the keel is missing. Does anyone know what I would use to replace it? Do you seal around the pin somehow? My friend asked about using 5200 marine sealant. We also found a small void (ding? hole?) in the hull under the water line. I am wondering if anyone has any recommendations for filling that. It isn't very deep but obviously has to be taken care of. Cherri M-15 #322 Cherri's Jubilee
