Important Notes

This listing is for the Honda GX200 gas engine only, in your selected starting configuration. Pumps, mounting brackets, pulleys, couplings, belts, batteries, and other equipment components are NOT INCLUDED.

The Honda GX200 is an excellent option for gas softwash system replacements, custom softwash builds, and smaller-GPM pressure washer applications. However, the engine must be properly matched to the pump's horsepower, RPM, and torque requirements. The GPM and PSI that a system can produce will depend on the pump and drive configuration selected.

The engine features a 3/4-inch keyed horizontal shaft, but shaft diameter alone does not guarantee compatibility with every pump or existing engine configuration. Verify shaft length, mounting dimensions, coupling requirements, and operating speed before ordering.

The electric-start model requires a compatible starting battery and associated electrical connections. Confirm battery and accessory requirements for your particular installation before purchasing.

Engine oil must be added and checked according to Honda's instructions before initial operation. Always follow the manufacturer's operating, maintenance, and safety recommendations.
