Combine marinade ingredients in large bowl. Rinse scallops and pat dry with paper towels. Cover scallops in marinade. Marinate scallops in fridge overnight or at least 4 hours, stirring occasionally.
Remove scallops from marinade. Skewer the scallops in pairs on doubled wooden skewers that have soaked for at least an hour in water. Scallop skewers should be grilled on high for a few minutes on each side. Squeeze lime over scallops when they are almost finished grilling. Serve hot
