The 3-cylinder 3JH40 has been developed by leading manufacturer YANMAR as the marine industry’s smallest CR inboard diesel engine. With an output of 40 mhp, it 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.

Offering minimal fuel consumption and exceptionally low noise and emission levels, the new YANMAR 3JH40 propulsion engine surpasses 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. Weighing 192 kg and with 1.642 L displacement, the engine can be operated by either standard mechanical cable controls or the YANMAR VC10 electronic control system.

Floris Lettinga, YANMAR MARINE INTERNATIONAL’s Senior Global Sales Manager, said: “We have launched the new YANMAR 3JH40 to answer the demand for a smaller common rail engine suitable for a wide range of commercial and leisure applications. By strengthening our JH-CR range of models, we are very pleased to introduce the significant benefits associated with common rail technology to more owners and operators. It is clear from the extensive variety of our new customers recently acquired that the YANMAR JH common rail range from 40 to 110 mhp has become the new global standard in sailboat propulsion.
