The new EVO420 petrol engine is a 14.0HP 4-stroke engine from Evopower, and part of a new series of engines. A direct replacement engine for the Honda GX390 engine, it's actually 1.0hp more powerful, producing an overall engine displacement 420cc, compared to that of the 389cc for the Honda GX390. The engine shaft and mounting holes however, are exactly the same which allows for an extremely quick and easy change of engines when your old one needs replacing.

With a brand new series of professional engines, Evopower have paid close attention to quality without the expense of a Honda or equivalent market leading engine. Evopower prides itself on the quality of its products and a full UK parts department are there should you require any additional parts in the future.

Perfect for construction, agriculture and recreational use, the EVO420 is made to an industrial and commercial grade, with cast iron cylinder sleeves meaning you can expect the inside of the engine to be durable. The EP190 recoil start 4-stroke OHV petrol engine is designed to be fuel efficient as well as being quiet and smooth running during operation.

Having made their name manufacturing pressure washers and compactor plates for a range of applications, Evopower have now made their own popular and well-tested replacement engines, suited for a range of applications and environments.
