Honda Gasoline Engine – 11 HP, 389cc, Recoil Start - GX390HI

Honda GX390 Gasoline Engine

The Honda GX390H1 is a highly reliable air-cooled, 4-stroke OHV gasoline engine engineered specifically for heavy-duty industrial, agricultural, and commercial applications. Built to drive demanding equipment such as tillers, generators, welders, and heavy-duty water pumps, this robust engine delivers a maximum power output of 11.1 HP (8.2 kW) at 3600 rpm from a 389cc displacement. Its advanced OHV design, paired with variable ignition timing, ensures excellent combustion efficiency. This results in high power output alongside reduced fuel consumption and exceptional exhaust emissions performance that meets the world's most stringent environmental legislation.

Designed for long-term durability in harsh work environments, the GX390H1 features a highly durable cast iron cylinder sleeve and purpose-built components that actively resist wear over prolonged use. Operator convenience is prioritized through an easy-to-grip soft recoil starter handle combined with an automatic decompression system, guaranteeing a smooth and effortless start every time. Supported by a generous 6.1-liter fuel tank, this engine provides extended, continuous runtimes for demanding work shifts while maintaining noticeably low vibration and noise levels for optimal user comfort.
