Boating Magazine recently examined the popular myth that 4-stroke outboard engines are more fuel efficient than 2-stroke engines. Comparisons are often made between older, carbureted two-strokes and newer fuel-injected four-strokes. In those cases, the enhanced economy comes from the fuel delivery system, not from the number of revolutions in a power cycle. Compare modern two-strokes like Evinrude’s E-TEC outboards to modern four-strokes, and the difference is too close to call.
Karl Sandstrom, product manager for BRP’s Evinrude Outboard Division, explains how the modern direct injected 2-stroke engines can compete head-to-head with, and in some cases, out-perform 4-stroke engines on fuel economy. He gives some great insight into the benefits of the new direct injected 2-stroke technology.
