Stir together first 4 ingredients. Arrange chicken pieces, skin sides down, in an aluminum foil-lined roasting pan. Sprinkle both sides of chicken with seasoned salt mixture. Squeeze juice from lime over chicken. Spread jerk seasoning on both sides of chicken. Cover with plastic wrap, and chill 8 to 24 hours. Let stand at room temperature 30 minutes.
Light one side of grill, heating to 350° to 400° (medium-high) heat; leave other side unlit. Arrange chicken over unlit side, and grill, covered with grill lid, 1 hour and 10 minutes or until a meat thermometer inserted into thickest portion registers 170°. Garnish, if desired.
*1 (8-oz.) bottle liquid Jamaican jerk marinade may be substituted.
