1. Combine first 6 ingredients in a small mixing bowl; whisk in olive oil in a slow, steady stream. Place scallops in a zip-top plastic freezer bag; add lime juice mixture. Cover or seal, and chill 30 minutes, turning once. Drain scallops, discarding marinade.
2. Microwave bacon, covered with paper towels, in 4 batches, at HIGH 3 to 4 minutes or until slightly brown. Wrap 1 bacon piece around each scallop, and secure with a wooden pick. Sprinkle evenly with salt and pepper.
3. Coat a cold cooking grate with cooking spray, and place grate on grill over medium-high heat (350° to 400°). Place scallops on grate, and grill, covered with grill lid, 3 to 4 minutes on each side or until bacon is crisp and scallops are done.
