Just to add a couple of thoughts to this thread… Generally there are pockets and cavities within the leg of most outboards that can trap water. The manufacturers provide drain holes for these pockets. The problem is that after time these drain holes, often pretty small can get plugged up with carbon, mud and sand. Look over the lower part of your motor leg, look for small holes, these likely lead to cavities within the leg… be sure that they are obstruction free. When dropping a leg to service the water pump, that is a good time to check from the inside for plugged drain passages .
