Two years after its first electronically-controlled common-rail engines became available, Yanmar Marine USA Corp now announces the next generation of its lightweight BY Series diesels. These state-of-the-art BY2 Series engines feature many new improvements, including a glow plug controller that virtually eliminates cold-start white smoke.
The Yanmar BY2 Series engine control unit has also been reprogrammed from torque to speed control, providing a smoother operation and better synchronization for twin engine applications. For simpler installation and servicing, the fuel inlet and return connections are now incorporated into a single manifold mounted on the lower side of the engine. A two-piece flywheel housing enable both sterndrive and inboard configurations. A full metal top cover and fully-jacketed, water-cooled exhaust manifold with modifications to the turbocharger and heat exchanger protect the fuel system components and result in a lower profile.
Employing innovative NMEA CAN-bus technology, the advanced BY2 Series diesel engines provide the same output as their powerful predecessors. The updated four-cylinder 150 and 180 hp models, as well as the six-cylinder 220 and 260 hp versions all meet the latest EPA and RCD emissions regulations.
