Yanmar Marine engine

4LH-DTE

In production 1990–2000

Yanmar 4LH-DTE: 170 hp (125 kW) at 3300 rpm, 3.455-litre turbocharged, intercooled four-cylinder marine diesel from the original 4LH series.

The 4LH is Yanmar's 3.455-litre four-cylinder marine diesel (100 x 110 mm bore and stroke) from the late 1980s and 1990s, built in four turbocharged output levels: 4LH-TE, 4LH-HTE, 4LH-DTE and 4LH-STE. It was replaced around 1998-2000 by the 4LHA series, which kept the same bore, stroke and displacement.

The DTE was the second-highest rating. Yanmar's 1998 catalogue lists it with a mechanical angle-drive marine gear as standard, and gives a continuous rating of 113.2 kW (154 hp) at 3200 rpm.

Its successor was the 190 hp 4LHA-DTE, later the 200 hp 4LHA-DTP.
