Hub and installation requirements

Requires an engine-specific Flo-Torq II or compatible SSR hub system, sold separately. Mercury FourStroke V8 and 350–400 HP Verado applications listed in the guide use SSR HD 8M0101603. Other engines require their exact listed kit; do not choose a kit from horsepower or spline count alone.

Choosing your replacement

Match the diameter, pitch and rotation stamped on your current propeller. Check the exact engine or drive model, year, gearcase and shaft against the manufacturer application table. This listing does not recommend pitch. Maintain the engine manufacturer's specified full-throttle RPM range under normal loaded operation.

Installation

Use the specified thrust washer, adapters, spacers, prop nut and retaining hardware. Follow the engine and hub instructions for lubrication and tightening torque; no universal prop-nut torque is provided here.

Original manufacturer photograph represents the propeller design. Selected dimensions may differ. The available photograph shows right-hand rotation; it is not a photo of the left-hand QS5007X.
