The NRS has extensive cup and a high rake angle. This prop provides very good lift. It is more aggressive than the RED and less agrressive than the PTR blade style. This is an excellent choice for flats style boats and dual motor, v-bottom off-shore applications. The NRS is perfect when replacing a Yamaha GYT, Turbo and Stileto, also the Michigan Rapture and the Mercury Laser. The 4-blade version provides better overall performance. Every PowerTech propeller is expertly crafted for high-performance and durability, even in the harshest saltwater conditions.

* 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.
