Cummins MerCruiser Diesel has extended its innovative Quantum diesel technology on the QSD2.0 platform with the release of the QSD2.0-170hp for inboard applications. This propulsion system is well suited for small, single-engine boats. The new package is EPA, RCD and IMO certified, and the QSD2.0-170hp engine, first introduced last spring, will still be offered with the Bravo One, Two and Three sterndrives. As announced last fall, the QSD2.0-170 is also available with the Alpha sterndrive with a 1.62:1 gear ratio, perfect for small runabouts. The QSD2.0 is offered in ratings from 115 to 170hp. The entire 2.0 family boasts a new turbocharger for increased power and an advanced ECM with SmartCraft compatibility to monitor various engine parameters. The QSD2.0 line also features advanced components such as the integrated heat exchanger and exhaust manifold, which help reduce overall package size and weight. Impressive acceleration and precise throttle response are the result of a proven high-pressure common-rail fuel system that includes seawater aftercooling.
