Fits 4" Motor Diameter. The props include the nut attachment and can be installed in seconds. The patented Weedless Wedge is the only 100% weedless prop in the history of fishing. And it delivers full power so there's no need to carry an extra prop and a wrench. The design behind the Weedless Wedge is both simple and brilliant. The leading edge on each propeller blade is shaped with a swept-back edge that always meets at an angle of less than 45 degrees. That wedges weeds away from the hub even at slow fishing speeds. Even through a jungle. Minn Kota MKP-33.
