The Honda GX160 is the most widely used small commercial engine on pest control and weed control power sprayers, and for good reason: it starts easily, runs smoothly, and lasts. This is the genuine Honda GX160UT2QX2, the standard recoil-start version with a 3/4" keyed horizontal shaft. It's an air-cooled, 4-stroke OHV engine rated at 5.5 gross HP, delivering 4.8 net HP (3.6 kW) at 3,600 RPM from 163cc, and it's backed by Honda's 2-year manufacturer's warranty. Orders over $199 ship free.

Keep your GX160 running with a fresh Honda GX160 air filter (17210-Z4M-821), especially in dusty Arizona conditions. Change the oil regularly, and use fresh fuel or a stabilizer before storage. Browse all Honda engines and parts, or shop the pumps they drive.
This engine ships ground only. FAA regulations don't allow it to ship by air.
This engine does not ship to California. The California Air Resources Board (CARB) prohibits the sale of these gas engines into California. To be exempt from CARB regulations, equipment must typically be used 51% or more in construction or farming. See CARB's guidance.
Engines that have been installed or have had gas put in them are not eligible for return, refund, or exchange. This ensures every customer receives an engine in brand-new condition.
