The All-New GCV pressure washer engine delivers more power and more torque for premium residential applications, along with a range of technological attributes, innovative features and a simple design that make the new model even more reliable and easier to operate and maintain. Net horsepower more closely correlates with the power the operator will experience when using a Honda engine powered product.
The power rating of the engines indicated in this document measures the net power output at rpm rpm for model GXH50, GXV50, GX25 and GX35 and net torque at rpm, as tested on a production engine.
Mass production engines may vary from this value. Actual power output for the engine installed in the final machine will vary depending on numerous factors, including the operation speed of the engine in application, environmental conditions, maintenance and other variables.
WARNING: This product can expose you to chemicals including soots, tars, and mineral oils, which are known to the State of California to cause cancer, and carbon monoxide, which is known to the State of California to cause birth defects or other reproductive harm.

Once the engine is up and running, the Auto Choke automatically returns to an optimal operating position. This system, which is connected to the camshaft, reduces compression by opening the exhaust valve slightly when the engine is being started. This reduces the amount of force needed to start the engine and improves starting performance.
The system disengages automatically after the engine starts to prevent any power loss during normal operation. Its lighter piston and other moving parts help keep vibration to a comfortable level.
It enables a variety of complicated electronic controls to be linked to improve operability. A truly innovative combination of a compact combustion chamber, overhead cam configuration and uniblock construction significantly reduces fuel and oil consumption as compared to conventional side-valve engines. Plus, simple construction has minimized the number of parts, making the engine more reliable and easier to operate.
New V-shaped valves and a pent-roof combustion chamber enable air in cylinder to flow more smoothly and maximizes the mixing of fuel. The longer stroke design also enhances turbulence in the cylinder, helping the mixture of air and fuel.
Drive-By-Wire unlike conventional models, has no throttle cable. An ECU controls a throttle motor via an electrical signal. Ideal throttle control is possible, from conventional type user-operated throttle control, to a variety of automatic control by the ECU. Electronic Fuel Injection EFI , which detects the state of the engine using sensors supplies the optimum amount of fuel to the engine according to its working conditions.
EFI Improves fuel economy, reduces exhaust gas, and achieves excellent usability and easy maintenance. Electronic Fuel Injection eliminates the need for a manual choke, making starting simple. In addition, starting is improved as the fuel is sealed within the injector and fuel hose reducing fuel deterioration, and making smooth engine startup possible even after long-term storage.
The electronic governor minimizes governor droop. This increases available power. For most normal engines, available power is decreased when the engine is approaching wide open throttle. Engine diagnosis utilizes Dr. The new integrated Fuel-Off position on the engine control allows the user to stop the flow of fuel to the engine when pressure washing is complete.
How does it work - With the engine running and the switch placed in the Fuel-Off position, the fuel flow to the carburetor is stopped.
The engine will continue to run until the majority of fuel remaining in the carburetor is consumed and the engine shuts down. Using the Fuel Off feature when shutting your pressure washer down helps prevent sticky carburetor buildup which makes for cleaner storage and easier future starting. Upright, sideways, even upside down — the Mini 4-Strokes will still run great. An exclusive Honda rotary-slinger lubrication system keeps oil in a completely misted state and circulates it using pressure fluctuations generated by the movement of the piston.
Built-in passages effectively return the circulated oil to the oil reservoir from every part of the engine. An oil return port positioned in the center of the reservoir prevents oil from accidentally flowing into the combustion chamber. This substantially reduces both oil consumption and the emission of unburned oil in the exhaust. The results include better all-around environmental performance and operating costs that actually decrease the more the engine is used! It offers the highest V-Twin compression ratio on the market.
The power is transmitted through forged-steel connecting rods and a forged-steel crankshaft, supported by a full-pressure lubrication system. The lubrication system uses a high capacity pump with discrete chambers.
This facilitates consistent oil delivery. Radically smart. It eliminates the head gasket, head bolts, and allows for more airflow and better cooling.
Speaking of cooling, improved cooling means better combustion management. Cooling is also improved by each of the lightweight aluminum pushrods being housed in a separate tube to achieve enhanced airflow.
When you put it all together with fewer parts you get an engine with reduced emissions and greater-than-ever durability. On some models, it also offers programmable governor and throttle modes for unprecedented flexibility. A diagnostic LED helps with trouble shooting. Stepper motors precisely control throttle and choke position. Control panel mounted LED indicator informs the user about potential problems using 10 different trouble codes.
The indicator is designed to stop the engine, or alert the operator of potential issues, helping to protect and extend engine life. Small engine timing belts are usually external and are subject to wear caused by dirt. The system consists of an oil level sensor inside the crankcase. When the oil reaches a level that is too low for safe operation, the engine warns you or stops automatically.
The OHV design, new V-shaped valves and a pent-roof shape of combustion chamber enable air in cylinder to flow more smoothly increasing combustion efficiency, allowing for higher compression ratios and greater power output.
The OHV layout, with enhanced valve positioning and combustion chamber, the new GCV pumps out an increase in torque of 18 percent and a nine percent horsepower gain over the GCV; GCV also showed a strong increase in torque of 13 percent and 10 percent horsepower gain over the GCV STR Governor Self Tuning Regulator minimizes engine droop seen with traditional mechanical governor systems by electronically regulating the throttle opening to maintain constant, stable engine speed even under changing load conditions, resulting in exceptional performance and enhanced user satisfaction.
The result:. Powerful, Simple, Reliable Power. Overhead valve OHV configuration and pent roof design increase combustion efficiency, allowing for higher compression ratios and greater power output. Learn More Powerful torque across a wide RPM range helps reduce engine speed drop from sudden load increases.
One of the lightest OHV engines in their class Simplified engine layout makes quick work of disassembly with fewer tools and quicker repairs.
Optimized muffler structure reduces engine noise and improves operator comfort Enhanced crankshaft balance results in lower vibration. High quality materials and purpose built components ensure reliable long term use Fuel-Off position allows user to run carburetor out of fuel making it less susceptible to contamination Learn More.
Auto Choke System eliminates manual operation making it easy to use for all operators Learn More Large diameter fuel opening reduces potential spills and makes refueling easier Long oil tube makes draining and filling quick and easy Easily accessible spark plug.
