This from the manual....
Robert, I have the manual for the 240 O'day and this is what it say's concerning the Keel: "The keel is an external,bolted on, lead casting. The keel is bolted to an external stub with three 3/4" stainless steel bolts. Additionaly, between the hull and keel casting is an epoxy adhesive. The external lead keel is generally recognized as the best way of attaching ballast in order to get the weight as low as possible. Also, an external lead keel provides much better impact resistance than either external iron or internal ballast of any type. The wings also aid in stability and give additionla "lift." " Sorry this might not be enough info. I would find someone with this type of experience and tools to do this job. I do remember asking on this forum who made the keel and a lead keel manufator in canada made the wing keel for our boat. Might do a google search to find them. also search this site for info I asked about the keel. Hopes this helps. Alan " The Wiser Choice"
