I Purchased this new two seasons ago to irrigate my property.  This machine has paid for itself time and time again it is easy to start . starts on the first pull. It’s pretty economical on gas so easy on the pocketbook.  I highly recommend this machine to anyone out there. I spent a lot of time researching and the only answer was a Honda.  I would not hesitate to buy another one.  The only thing I would do to improve the machine would be to make a wheeled kit available for it. Thanks Mander for making this machine.  For a city boy who’s become a country boy Honda is the way to go.

Throws much water! Always starts with one pull

I've used this model pump for several years. I am in the construction field and I use it to de-water basements and fill a 1500 gallon hydro seeder.  This pump has given nothing but excellent service and when compared to other pump makes I've used these are head and shoulders above the rest.  This pump is extremely productive, fairly lightweight, and would start on one pull in near freezing temps! I am very satisfied with it and I only use Honda pumps for their continuous reliability!
