The Dyna Jet Cupped, which is a Michigan Wheel Federal Series ski boat propeller, is designed for high-power fast bottom boats.

Dyna jets propellers are made of a NiBrAl (Nickel, Bronze, Aluminum) alloy which provides extra strength, less flex, and greater durability.

With the Dyna Jet prop, the trailing edges of the blades are cupped for extra speed. Cupping also adds camber, maximizing thrust, and minimizing vibration of a cavitating propeller.
