Yanmar Marine engine

4JH-HTE

In production 1985–1989

Original-generation Yanmar JH diesel: turbocharged and intercooled 1.644 L inline four rated 66 hp at 3600 rpm.

The original JH series was Yanmar's first four-cylinder JH family: a 78 x 86 mm, 1.644 L direct-injection, freshwater-cooled block with a Yanmar YPES in-line injection pump, shared by four ratings (4JHE, 4JH-TE, 4JH-HTE, 4JH-DTE). It was replaced by the larger-bore JH2 series (1.817 L) at the end of the 1980s.

The 4JH-HTE uses a water-cooled IHI RHB52HW turbocharger with a seawater-cooled plate-fin intercooler and the heavier KBW21 gear.

Its successor was the 4JH2-HTE.
