The DuroMax XP9HP is one of our most compact and lightweight engines available, but don’t let the size fool you. This powerful 274 cc 4-stroke OHV engine has plenty of power for multiple light duty applications including go karts, pressure washers, trailer-mounted mobile carwashes, log splitters, rototillers, cultivators, and water/trash transfer pumps. The XP9HP is equipped with convenient features such as a large 1.3-gallon gas tank for longer runtimes and an E-Z pull recoil starter for starting the engine with ease. This engine is EPA and CARB approved for safe mandated use.
