Combine all the ingredients except the fish in a small bowl.
Score the fish several times.
Pour the marinade over the fish and coat on both sides.
Place in the refrigerator for 1½ to 2 hours, turning from time to time and spooning the marinade over the fillets.
Towards the end of the marinating time, start the charcoal or gas grill.
Take a large sheet of foil and poke holes in it (small enough to keep the fish away from the grill but plentiful enough to let the smoke come through).
Place the foil on the grill and, trying to avoid the holes, spoon on some of the marinade.
Add the fish and cook for 8 to ten minutes on each side, basting as you turn.
