Reduce oven temperature to 325 degrees and cook an additional 1 hour and 30 minutes or until thoroughly heated. Baste ham with maple syrup mixture every 30 minutes. Transfer ham to a platter, and let stand 15 minutes before slicing. Combine remaining syrup, remaining mustard, and marmalade in a small saucepan.
