HONDA UMC425 Powerhead

As the largest single cylinder engine of Honda’s flagship GX range, the Honda GX390 Stationary Engine is used in all sorts of applications. From Pressure Washers and Construction/Industrial equipment, to Tillers/Cultivators, Generators and Commercial Lawn & Garden Equipment, it can be found working hard all over Australia. Due to its power and emissions compliance, heavy-duty Forestry Equipment, Agricultural Equipment and Water Pumps are also powered by the gutsy GX390.

EASY ON YOUR POCKET, HARD-WORKING

A digital CDI ignition system with variable timing and an increased compression ratio combines with the GX390’s Precision Camshaft design to offer precise valve timing and optimal valve overlap for better fuel efficiency. It draws on decades of Honda engineering with its OHV design, delivering increased efficiency and optimal power transfer where and when you need it. The use of lightweight, noise-reducing materials and a forged steel crankshaft & rigid crankcase results in an exceptionally quiet engine – an improved piston design reduces mechanical noise, with an overall reduction of engine noise by up to 5 dB.

PROVEN RELIABILITY

The Honda GX390 Stationary Engine offers precision-engineered components resulting in lower vibration, and a Ball Bearing-supported Crankshaft for greater stability. It also offers an improved piston design and a heavy duty balancer shaft to deliver smooth performance. Helical cut gears, a large capacity, multi-chamber exhaust system and sophisticated air intake system also makes for an exceptionally quiet engine. And with Oil Alert, a simple Throttle Control, large Fuel Tank and Automotive Type Fuel Cap, Dual Oil Drains and Fills, an easily accessible Spark Plug and Heavy Duty Recoil Starter, the Stationary Engine GX390’s features go on and on.

3 YEAR WARRANTY

Just like the entire GX Engine range, the GX390 is covered by an extensive Honda 3 Year Domestic and 1 Year Commercial Warranty. And for those who want a little bit more, available extras include Gear reduction options, Electric start option, Spark arrester and Charge & Lamp Coils with Multiple Output Options. Low profile versions also available.
