Product description

Safe and reliable

  • The safety factor of shafting parts is higher than the ship code standard, so as to ensure the safety and reliability of parts
  • Side-pulling bolts are arranged on engine block to ensure the optimal stress distribution of the engine block, so as to reduce the deformation of parts and improve the service life
  • Replace the filter without stopping

Strong power

  • High power, about 15% higher than similar products
  • High explosive pressure, about 20% higher than similar products
  • The maximum torque output can be maintained at 70%-100% rated speed, and the range of high torque speed is wide

Economical and fuel-efficient
