Powerfin

The company headquarters is located in Hurricane, Utah, although it was formerly in El Campo, Texas and originated in Arlington, Washington.

[2][3][4][5][6] Powerfin produces carbon fiber two, three, four and five-bladed propellers for two-stroke and four-stroke engines up to the Rotax 914 of 115 hp (86 kW).

[2][4][5][6] The company is noted for its use of the Clark Y airfoil, infinite blade angle adjustment, as well as for the very low rotating inertia of its designs, a key wear factor on lightweight engine gearboxes.

The propeller blades are constructed of carbon fiber and aramid pre-preg cloth with a foam core, and cured in an autoclave.

The company's Apex series of two- to five-bladed propeller hubs were CAD/CAM designed and are created on a Haas VF-4 CNC vertical milling station.
