Mix Marinade Mix, oil, vinegar and water in small bowl. Reserve 1/4 cup for brushing. Place shrimp in large resealable plastic bag or glass dish. Add remaining marinade; turn to coat well. Refrigerate 15 minutes or longer for extra flavor. (Marinate seafood no longer than 30 minutes.)
Meanwhile, cut bacon slices in half to make 16 pieces. Place 2 layers of paper towels on microwaveable plate. Place 8 pieces of bacon in single layer on paper towels. Cover with 1 layer of paper towel. Microwave on HIGH 2 to 4 minutes or until bacon is partially cooked. Repeat with remaining bacon. Set aside.
Peel pineapple then halve lengthwise. Cut off core from each half. Slice pineapple crosswise so pieces are same thickness as shrimp. Wrap 1 piece bacon around each pineapple slice. Remove shrimp from marinade. Discard any remaining marinade. Alternately thread 2 shrimp and a bacon-wrapped pineapple onto each skewer.
Grill skewers over medium-high heat 4 to 6 minutes or until shrimp is cooked through, turning occasionally and brushing with reserved marinade.
