The propeller holds a rotating hub and radiating blades that create a helical spiral and exert linear thrust on a working surface when spun fluid such as water.
Propellers drive a boat over water or pump fluid via a pipe or duct. The blades have a design that their rotating motion through the fluid generates a pressure differential between the blade's surfaces. The majority of naval propellers are screw propellers with helical blades that rotate on a propeller shaft with a nearly horizontal axis.
Propeller 4889-3130-19 provides a good stern lift featuring 15 tooth spline and 4.25-inch gearcase exhaust, and a rubber-mounted hub.
