First introduced as an outboard drag racing propeller, the Lightning E.T. also delivers top performance in a variety of single-engine recreational boat applications, including bass, flats and modified vee bottom boats running up to 300hp. Besides delivering an incredible hole shot and awesome acceleration, the Lightning E.T. also produces natural bow lift, reducing drag and increasing the efficiency of the boat. This adds up to higher speeds and better fuel economy with less engine trim - because less horsepower is used to lift the boat, and more power is devoted to achieving top-end speed and acceleration. The exclusive Mercury  X7  alloy makes the Mercury Racing® Lightning E.T.® propeller extremely durable.
