Cook bacon in a frying pan until beginning to crisp. Blot on paper towels. Pat scallops dry and season with salt and pepper.
Wrap each scallop with a half slice of bacon; thread 2 scallops onto each skewer. Stir Ketchup with honey, soy sauce, lemon juice and garlic. Brush half of the sauce mixture over the scallops.
Grill kabobs for 3 to 5 minutes per side or until cooked through. Baste with remaining sauce during cooking.
