Remove the ham from its package and pat it dry with paper towels. Score the ham by cutting into the rind of the ham in a diamond pattern making sure that the cuts are approximately 1/4-1/2" deep. Place the pan in a large disposable aluminum pan. Place 2 cups of water in the bottom of the pan around the ham.
Preheat the grill to medium high indirect heat (approximately 350 degrees F). In order to set this up, preheat the grill over medium high heat with all the burners on for 15-20 minutes. Then turn off all the burners except the outside burners and leave the middle burners off. Put the ham in the pan in the center of the grill over one of the burners that is off.
Cook for 1 1/2 to 2 hours until the ham reaches an internal temperature of 135 degrees F in the thickest part of the ham.
While the ham is on the grill, place the honey, bourbon, dijon mustard, salt and pepper in a small saucepan. Simmer over medium heat, whisking the ingredients together and cook until the honey melts (5-6 minutes) to make the glaze.
Baste the ham with the glaze during the last 30-45 minutes of the cook time. Brush the ham with the glaze every 10-15 minutes until the ham is cooked through.
Once the ham is heated through, let the ham rest at room temperature for 15-20 minutes. Then carefully move the ham to a large cutting board. Then carve the ham into large slices and enjoy!
