A vee bottom boat having one or two inboard engines with the drive shafts thereof extending through the hull to position a propeller in a position such that when the boat is planing at cruising speed the propeller will be surface-running or operating in half-submerged condition. A rudder is located directly in rear of the propeller. A partly cylindrical splash guard is provided over the propeller and prevents "rooster-tailing." In addition, a water supply duct having a radius approximating that of the propeller is provided extending forwardly a short distance from the propeller. A transmission connecting the engine to a propeller shaft includes a chain which permits advantageous location of the propeller shaft relative to the engine and its output shaft.
