For an engine of its size, the GXH50 is surprisingly adaptable, and can be used to power a range of different products.

Agricultural equipment and Construction & Industrial equipment are just some of the products that get their power from the GXH50.

And the fact that one of Honda's own Water Pumps is powered by the GXH50 is a testament to the durability and reliance that can be placed on this little upstart.


The GXH50 uses a precision camshaft to form part of Honda's world-famous OHV design for increased efficiency and optimal power transfer.

It features a high compression ratio for better fuel efficiency than comparable engines, so the GXH50 will end up lighter on your pocket in the long run.

With a large fuel tank, oil alert, easily accessible spark plug, and high quality materials, fit and finish, it's a proven performer.


The GXH50 incorporates a ball bearing-supported crankshaft for greater stability, and its precision engineered components result in low vibration levels.

A large capacity, multi-chamber exhaust system and sophisticated air intake system equate to exceptionally quiet operation.

The forged steel crankshaft and rigid crankcase, and the light weight, noise-reducing materials that are used throughout, reduce mechanical noise for easy use.
