BUKH solas marine engine

270ps (199kW) ace. to ISO 8665

Piezo controlled common rail injection system delivers 270ps and 57,6kg-m torque from the 3.0 liter V6 Common Rail Direct Injection (CRDI) engine. Advanced design also makes it ultra light, quiet and fuel efficient with its dimensions extremely compact.

Durability and Reliability Advantageous is the use of Compacted Graphite Iron (CGI) for the cylinder block. The CGI block is lighter and quieter than conventional grey cast iron and demonstrates at least 80 percent higher tensile strength, 45 percent higher stiffness and approximately double the fatigue strength of iron and aluminium. It lasts longer than anyone of us ever expected. It is the source of innovation and improvement in the marine engine industry.
