The present experimental datasets provide the open-water performance characteristics of surface-piercing propellers under various operating conditions. The open-water tests were conducted in a towing tank, considering various pitch ratios, immersion ratios, shaft inclination angles, and Froude numbers. The model propellers were of two different modified shapes of the Model-841-B with different pitch ratios. Thrust, torque, and efficiency were measured and calculated for each condition. A high-speed camera was used to observe the ventilated cavity around the propeller. The datasets included a detailed description of wedge-shaped support blocks to vary shaft inclination angles and a spray shield to eliminate the effects of spray on the data acquisition system under surface-piercing conditions. Descriptions were provided for a streamlined underwater casing and filming techniques designed to prevent the flow from affecting propulsion performance. The datasets can be used to enhance the understanding of the effects of operating conditions on the propulsion performance of surface-piercing propellers. The datasets will serve as benchmark data for predicting the open-water performance of surface-piercing propellers.
