ABSTRACT:
This invention is directed to an improved tandem marine propeller having sets of radially extending blades which are connected at their roots to a hub in tandem arrangement for minimizing drag adjacent the hub and having the blades configured by skewing one set forward and the other set backward and raking the blades of the two sets toward each other so that outer portions of the blades are equispaced radially about the hub and lie substantially in a common plane of rotation whereby loading on the blades of both sets is substantially equalized for increased efficiency.
