We live in a world of fast-paced technological innovation; many consumer products are being replaced or updated quarterly or even monthly. Mercury Racing® embraces wide-open innovation and the concept of constant product development, but we also believe in the old axiom “don’t fix what’s not broken.” Which is why, 25 years after its introduction, the Mercury Racing Lightning E.T.® propeller remains in our product line. The Lightning E.T. is no legacy product. It is still running strong as one of the most-efficient propellers for lightweight, two-stroke outboard-powered applications.
There’s been a surging interest in outboard drag racing and for competitors running our lightweight, high-revving Mercury Racing 2.5 liter motors, the Lightning E.T. continues to dominate, offering outstanding acceleration and top-end speed performance. What makes the Lightning E.T. so efficient? Its over-the-hub design, limited blade area and ample tip cupping combine to produce a propeller that spins up quickly and stays hooked up at high engine heights. The Lightning E.T. produces natural bow lift, thus requiring less trim for maximum speed – less horsepower is used to lift the boat and more is devoted to top-end speed and acceleration. With the Flo-Torq II Delrin® Hub System, the Lightning E.T. accepts both 1.0- and 1.25-inch solid hub kits for legacy CLE, 2.5 liter Sport Master, and 3.0 liter Sport Master gear cases.
In recreational applications, the Lightning E.T. shines on river runs and performance bass, flats and modified vee bottom boats. The Lightning E.T. provides a confidence-inspiring ride for hulls that generate lift at speed, on boats from Allison to STV and everything between. The Lightning E.T. has done it for 25 years and is still leading the way. What is your favorite Lightning E.T. equipped setup?
