BY3 Sterndrive Series 150-260mhp

BY3 Sterndrive Series 150-260mhp
Hailed as setting new standards for the boating industry, the leading-edge BY3 series engines continue at the same output as their predecessors but incorporate many upgrades, including the reprogramming of the ECU from torque to speed control, providing even smoother operation and better synchronisation on twin-engine applications. Choose from shaftdrive or the hydrodynamic YANMAR ZT350 sterndrive. These tough but lightweight, common rail electronic BY3 diesel meet the latest EPA and RCD emissions regulations.
