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, roto tillers- cultivators, and water/trash transfer pumps. The engine is equipped with convenient features like a large 1.3-gallon gas tank for longer runtimes, an E-Z pull recoil starter for starting the engine with ease, and EPA and CARB approved for safe mandated use.
