4JH3E
JH3-generation Yanmar diesel: naturally aspirated 1.995 L inline four rated 56 hp at 3800 rpm.
The JH3 series (1999 to mid-2000s) moved to an 84 x 90 mm bore and stroke: 1.496 L for the three-cylinder 3JH3E and 1.995 L for the four-cylinder models, rated at 3800 rpm. Yanmar marketed it as lighter and quieter than the JH2 and compliant with the EU BSO emission rules. Package letters in the code denote the drive: B = KM3A/KM4A down-angle gear, T = KBW21 parallel gear (turbo models), H = KMH4A hydraulic down-angle gear, C = saildrive.
The 4JH3E replaced the 4JH2E. Gear options were KM3P parallel, KM3A down-angle (4JH3BE), KBW20-1 parallel and KM4A1 down-angle packages, and SD31/SD40 saildrive versions (4JH3CE).
It was replaced by the 4JH4E in 2004.
