4JH45
Common-rail Yanmar JH-CR diesel: naturally aspirated 2.19 L inline four rated 45 mhp at 3000 rpm.
The JH-CR series is Yanmar's electronically controlled common-rail JH generation, launched in 2014 with the 4JH45, 4JH57, 4JH80 and 4JH110 and joined by the three-cylinder 3JH40 in 2018. It is based on Yanmar's TNV industrial block with a Bosch common-rail system and ECU, keeps roughly the footprint of the mechanical JH engines for repowers, works with mechanical controls as standard or the VC10/VC20 electronic vessel-control system, and complies with EPA Tier 3 and RCD 2. Yanmar certifies it for recreational and light-duty commercial use.
The 4JH45 and 4JH57 share one naturally aspirated 2.19 L engine and differ only in rating; they succeeded the mechanical 4JH5E. Gear options are KM35P, KM35A2, KM4A1, ZF30M, ZF25 and ZF25A, or the SD60-5 saildrive.
