We propose a modal synthesis method for solving this type of problem, coupling dynamic substructure of Craig and Bampton type and acoustic subdomain based on a pressure formulation. The application of the proposed method is performed on a boat propeller with four blades, in air and water. Our numerical results are confronted to some experimental study which allows validate jointly the calculation process and the proposed method.}}
