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.
