In a medium-sized mixing bowl, add the olive oil, Old Bay seasoning, lime juice, and lemon juice.
Using a wire whisk, mix well.
Place the tuna steaks in a shallow dish.
Pour the marinade over the tuna steaks and turn them occasionally to coat evenly.
Let the tuna marinate for 20 minutes.
Preheat the grill until it's hot.
Place the tuna steaks on the hottest part of the grill and sear for 1 to 2 minutes on each side.
Move the tuna steaks slightly away from the hottest area of the grill and cook for 8 to 10 minutes per inch of thickness.
If desired, squeeze fresh lemon over the tuna before serving.
