Heat a grill to medium and grill the andouille sausage, turning occasionally, until cooked through. Slice into 2-inch rounds.
Combine the seafood broth, potatoes and onion in a medium pot, bring to a boil and then reduce to a simmer. Cook until the potatoes are tender, 3 to 4 minutes. Add the andouille sausage, corn, shrimp, crab, clams and tomatoes.
Return to simmer and cook until the shrimp are cooked through, 3 to 4 minutes. Stir in the lemon juice and basil.
