4JH3-DTE
JH3-generation Yanmar diesel: highest-output turbocharged and intercooled 1.995 L inline four, 125 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 4JH3-DTE was supplied mainly with the KMH4A hydraulic down-angle gear (4JH3-DTHE; US market code 4JH3-DTBE), later also KM4A2, and suits small motorboats and heavier sailboats. It had no direct 125 hp successor in the JH4 series (the 4JH4-HTE tops out at 110 hp), and Yanmar's EMEA site still carried a 4JH3-DTE product page with EPA Tier 2/RCD 1 certification in 2020-2026.
