* 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.

      PowerTech!' patented
CushionLok hub
    system is a modular (fits all motor brands simply by changing driver and/or hardware), adjustable, field-serviceable design (no more trips to the local prop shop for a rehub) which, not only, withstands higher heat and torque loads than standard, press-in-style rubber hubs, but affords maximum drivetrain protection and super-soft forward and reverse drive engagement, as well. The hub system' cushioned rotation comes from the rotational movement of the propeller about the hub, which is allowed by the compression of the black cushioning rods inside hub cavity. In essence, the CushionLok hub acts as a rotational shock absorber, both, on drive engagement and in the event of an impact.
