Winner of the Miami 2018 Innovation Award for the Inboard Engine category.



YANMAR introduces the 3JH40 as the world’s smallest common rail inboard marine diesel engine in displacement, dimensions, and weight.



The 3-cylinder 3JH40, with an output of 40 mhp, will enable a whole new category of smaller leisure boat owners and commercial vessel operators to benefit for the first time from the efficiency and performance advantages associated with the most recent electronically-managed CR fuel-injection technology.



With an output of 40 MHP @ 3000 rpm (29.4 kW @ 3000 rpm), the 3JH40 is the smallest common rail inboard marine diesel in:



  • Displacement, with only 3 cylinders measuring 1.642 L (100 cu in)
  • Physical size, measuring 774 x 580 x 632mm
  • Weight, measuring 192kg without gear

Through common rail technology, the 3JH40 offers minimal fuel consumption and exceptionally low noise and emission levels, exceeding EPA Tier 3 and EU RCD Tier 2 emission regulations for virtually smoke and odor-free operation.



The 4-stroke, water-cooled 3JH40 is an ideal solution for new builds and repowering applications, specifically monohull sailing yachts and catamarans up to 45ft, small motor boats or sloops, and light duty commercial craft.



*The next largest common rail inboard marine diesel engines are the YANMAR 4JHCR line: 45, 57, 80, 110 MHP.
