The Michigan Dyna-Quad propeller design provides the same performance and speed characteristics as the Dyna-jet but recommended for vessels over 40’. The larger blade area makes accommodations for the added weight and thrust requirements of a bigger vessel. The four blades have the same speed and “dig” as a three blade with the added benefits of smooth maneuverability. The Dyna-Quad propeller is also a great choice for the commercial boat operator who demands a high level of performance.
