とを特徴とする高速艇用プロペラ。In a propeller for a high-speed boat that operates in a diagonal flow state, a hole is formed in the blade root of the propeller blade, passing through from the blade pressure side to the blade back side, and the circular passage is such that the front side opening is smaller than the rear side opening. A high-speed boat propeller characterized by a diagonal opening near the leading edge of the propeller.
