Yanmar Marine engine
4JH4E
In production 2004–2006
Early JH4-generation Yanmar diesel: naturally aspirated 2.19 L inline four rated 54 hp at 3000 rpm.
The JH4 series (2004) introduced a new 88 mm-bore block and combustion system for the naturally aspirated models (3JH4E 1.642 L, 4JH4E 2.19 L) with the rated speed cut to 3000 rpm; Yanmar claimed about 25% more torque and lower noise than the JH3. The turbo JH4 models (4JH4-TE, 4JH4-HTE) kept the 84 mm-bore 1.995 L block at 3200 rpm.
The 4JH4E replaced the 4JH3E. It was sold with KM35A (and other KM gear) shaft packages or the SD50 saildrive. From January 2007 it was superseded by the 4JH4AE, the same rating with a redesigned injection pump.
