• Prop Spec: Diameter 10.3"X13" Pitch, 13 Spline Tooth, 4 Blades; Compatible with Mercury spitfire engines 25/30/35/40/45/48/50/55/60/70/75 HP
• Material: Made of high-strength aluminum alloy, lightweight and durable, surface treated with coating, with good corrosion resistance
• Superior Water Grip and Acceleration: At the same rotational speed, the 4-blade design offers greater total blade surface area in contact with water, enabling more efficient conversion of engine torque into forward thrust. Acceleration from standstill to glide is more rapid and powerful.
• Unparalleled Smoothness: More evenly distributed blades significantly reduce vibration and noise. The vessel operates with enhanced stability and quietness, greatly improving onboard comfort.
• Enhanced heavy-load/towing capability: Robust low-RPM thrust makes it ideal for towing operations; when the hull is deeper in the water, powerful low-end torque is even more essential for propulsion.
