Yanmar Marine engine
4JH2E
In production 1989–1999
JH2-generation Yanmar diesel: naturally aspirated 1.817 L inline four rated 50 hp at 3600 rpm.
The JH2 series (c. 1989-1999) uprated the JH family with a larger 82 mm bore (82 x 86 mm): 1.817 L for the four-cylinder 4JH2 and 1.363 L for the three-cylinder 3JH2. It was replaced by the JH3 series in 1999.
The 4JH2E replaced the 4JHE. Yanmar's 1990 operation manual lists the 4JH2 family with KM3P2 cone-clutch (4JH2E only), KBW20/KBW21 multi-disc parallel gears and KM4A down-angle gears; 'B' in the model code (e.g. 4JH2-TBE) denotes the down-angle gear package.
It was succeeded by the 4JH3E (1.995 L) in 1999.
