Honda Horizontal Engine 11.7 Net HP 389cc ES 1" x 3-21/32" #GX390-PAE2

In 1983, Honda Motor Company developed a revolutionary new 4-stroke, overhead valve engine that defined the future of small engine technology.

Now, almost 27 years later, Honda introduces the next generation of GX engines by offering more power, more quiet, less fuel consumption and less emissions than ever before. All this in a configuration that doesnt require modifications to equipment currently set up for the current GX Series.

More Power

The new Honda GX Series engines offer up to 6% more power over the original models. The increase in power is achieved through several innovative improvements.

Less Noise

Youll enjoy noise reduction levels ranging from 2.5 to 8db thanks to Hondas re-designed air cleaner and muffler. Vibration levels have also been reduced through the use of an all new, light weight piston.

Less Fuel

Fuel consumption has been reduced by 10% through dramatically improved combustion efficiency. The new GX series offers:

This means longer runs times and lower fuel costs for Honda owners.

Same Footprint

OEMs can pass along new improvements and features without having to worry about costly and time consuming product modifications. New GX Series models have the exact footprint and fit into the same envelope as their similarly sized predecessors.

EPA Phase 3 Ready!

Once again, Honda leads the way in offering power solutions that meet EPA Phase 3 emission regulations well ahead of schedule.

Even more importantly, Honda GX engines meet these regulations without the need for a catalyst.
