H22 Leaks

[Carina22]

I have a new to me 1983 H22. The boat sat on a trailer for at least 5 years and when I launched it a couple of weeks ago, the boat took on water to the extent of a couple of inches per day - although with an automatic bilge pump, the water ingress may have been much greater. I have the boat in a yard now and am in the process of replacing the centerboard keel bushing and resealing the assembley and am going to replace all three through hulls. Is there anythig else I should do while the boat is out of the water? Any thoughts or experiences with leaks on a Hunter 22 or other would be appreciated.

I would think thru hulls or the cockpit drain hose is split. Also check the sea **** for leaks around the valve stem maybe.
