BUKH S270

BUKH SOLAS MARINE DIESEL ENGINE
270 HP (199 KW)

The BUKH S-Series Piezo controlled common rail injections system delivers 270 HP and 57,6 kg·m torque from the 3.0 liter V6 CRDI engine.

The advanced design also makes it ultralight, quiet an fuel efficient with extremely compact dimensions. The CGI block is lighter and quieter than conventional gray cast iron and demonstrates at least 85 percent higher tensile strength, 45 percent higher stiffnee and approximately double the fatique strength of iron and aluminum.
