DESC: Minn Kota's Weedless Wedge for your 712 is the only patented weedless prop on the market today. The weeds are "wedged" away as you sweep through the water because of each blade's swept back edge, keeping the weeds away from your motor. Because of this brilliant design, this prop will deliver maximum power to your motor, eliminating the need to have an additional prop on hand. This inventive and simple idea will allow you to go to waters you've been unable to pass through! trolling motors
