Grilled Salmon

I'm really sorry, but first of all, I have to say EW. Anything fish related on here (except for canned tuna) is all Patrick's doing. I don't like it one bit (I know, I'm missing out, blah blah but even the "slight" smell of salmon grosses me out. Anyway-since we have the grill now and I don't have to cook it inside Patrick can make all the salmon he wants. He found this recipe for a "yummy" marinade (had to take his word for it).

1 1/2 pounds salmon fillets
lemon pepper to taste (he used 1/4c lemon juice and 1/4tsp pepper, per reviewer suggestion, since we don't have lemon pepper)
garlic powder to taste
salt to taste
1/3 cup soy sauce
1/3 cup brown sugar
1/3 cup water
1/4 cup vegetable oil

Season salmon fillets with lemon pepper, garlic powder, and salt. In a small bowl, stir together soy sauce, brown sugar, water, and vegetable oil until sugar is dissolved. Place fish in a large resealable plastic bag with the soy sauce mixture, seal, and turn to coat. Refrigerate for at least 2 hours.

Preheat grill for medium heat. Lightly oil grill grate. Place salmon on the preheated grill, and discard marinade. Cook salmon for 6 to 8 minutes per side, or until the fish flakes easily with a fork.
