The Michigan Wheel Dyna Quad propellers are the predecessor of a newly designed series called Michigan DQX. The design has been modified to work better under heavy loads and in limited clearance areas. The latest technologies have been deployed in manufacturing the mold casting and or in the machine finishing process, thus increasing product accuracy and repeatability. The option to order size specific, in a range of bores, and with or without all degrees of cup is available. All “X” series propellers are CNC machined to facilitate very accurate and repeatable product.
