In small bowl, combine all ingredients, except salmon. Whisk until well combined. Pat fillets dry with paper towels.
Place salmon in a 1-gallon recloseable food storage bag; pour marinade over salmon. Seal bag and marinate, in refrigerator, at least 30 minutes or up to 2 hours.
Prepare grill to medium heat. Remove salmon from marinade; discard marinade. Place on grill; grill salmon 10 minutes per inch of thickness, or until fish flakes easily with fork, turning over half way through cooking.
