Dyna-Quad 4 Blade Propeller


0.69 E.A.R. - Diameter range: 17" - 46"

Like the Dyna-Jet, the four blade Dyna-Quad is one of the most popular recreational boat propellers in the world. The extra blade blade is advantageous for applications with increased thrust, constrained diameter, and/or noise and vibration concerns. The Dyna-Quad provides excellent performance, durability, and smoothness, making it a great choice for a wide range of boats.

Michigan Dyna-Quad propeller features include

A smoother operating propeller than a 3 blade propeller.
Your best choice if you require less vibration and increased fuel economy.
Made in the USA by Michigan Wheel Corporation - Grand Rapids, Michigan

Because of the many factors that are involved in sizing the correct inboard propeller, we no longer offer inboard propellers on line. Please call us at 800-446-9733, or email us at with your specific requirements. 

Bronze or Nibral: Most propellers are available in Bronze and in Nibral. Propellers that are over square (pitch is larger than diameter) are usually only available in Nibral because of the higher strength. If Nibral is the only option available the propeller is not available in Bronze. Bronze propellers are usable on boats with up to 200HP and Nibral should be used on boats with motors over 200HP. Special requests are possible but please call for availability.  

SPECIAL NOTE: Michigan Inboard Props are not returnable as they are stocked in a factory pilot bore and are machined to your boats shaft size. It is the customer's responsibility to provide accurate propeller bore dimensions. Inboard Propellers are purchased at the risk of the consumer and as such are advised to make sure the size and dimensions are correct for their boats requirements.
