PowerTech Boat Propeller | OSN Series | Motors 70 - 140HP

The OSN has a swept blade design with a narrow tip. It is an OEM equivalent for newer style OMC SST. It is available in 3 or 4 blades. The 4-blade version provides better overall performance including lift, hole-shot, handling and overall gip. Recommended for OMC engines. Every PowerTech propeller is expertly crafted for high-performance and durability, even in the harshest saltwater conditions.

    • Pressed-in rubber hub or Square universal hub*
* Square hubs (Flo-torq) consist of a square-profile sleeve. The primary advantage of square hubs is modularity, not performance, as the square hub can fit many motors with only hardware changes, but they tend to have two primary performance disadvantages, one, they tend to have a significantly shorter longevity, as compared to rubber hubs (depending on the application and conditions), and two, depending on the hub material chosen, they can create a hard connection from the prop to the shaft, so that any vibration is transferred directly to the shaft, the motor, and consequently, the boat.
