Whisk lime juice, 2 tablespoons of the oil, lemon juice, honey, ½ teaspoon salt, and ginger in a small bowl. Pour over the mango mixture, cover and chill for 1 hour.
Preheat your grill to medium heat.
Rub the top of the salmon with the remaining 1 tablespoon oil and season with salt and pepper.
Grill fish, skin side down (without flipping), over indirect heat for 16 to 18 minutes, or until easily flakes with fork.
Use an extra large spatula or rimless baking sheet to gently lift salmon off the grill, leaving skin on the grill rack.
Allow the salmon to cool for about 5 minutes.
