During today’s International Boatbuilders Exhibition and Conference (IBEX) trade show in Louisville, Ky., Mercury Marine unveiled its new Enertia ECO propeller line. Available in left- and right-hand rotations and 17-, 19-, 21- and 23-inches pitches, the 16-inch diameter three-blade props reportedly deliver a 10-percent increase in fuel economy at cruising speeds.
“Mercury Marine already produces fuel-efficient engines, as well as driver aids such as the ECO Screen display,” said Jared Reichenberger, brand manager for Mercury Propellers, in a press release from the company. “As marina gasoline prices have continued to rise, however, customers are increasingly focused on fuel economy. We realized an appreciable fuel economy gain could be found in the design of the propeller itself.”
According to the release, the efficiency gains reaped by the Enertia ECO propellers line are a byproduct of their design, which features large blade surface area and progressive rake that was made possible by building the props with Mercury’s X7 stainless steel alloy. While the Enertia ECO design reportedly results in reduced hull drag through increased bow lift at cruising speeds, it still matches the performance of other Mercury propellers such as the Enertia and Revolution 4, according to the press material.
Price is $795 per propeller.
