Cast-Ironed Sleeved engine? peak 4,400 watts, 3,500 Constant. Runs 8 hours at 50% constant power (1,750 watts)
Wouldn't buy it.
Cast iron sleeve is desirable. On real cheap engines you just have the pot-metal block machined to create the cylinder walls while adding an iron sleeve will withstand the heat and wear better. Nobody is going to make such a very heavy (iron) and expensive (either iron or aluminum) block out of solid cast iron or aluminum for a consumer grade engine. An industrial rated engine would cost more than $300 by itself.
Granted, in this engine size/class you might not even be able to find one that doesn't have a cast iron sleeve, the "desirable" feature improvements in this type would be overhead valves and (type of) float carb used, as well as being a name brand engine so you have higher availability of replacement parts. It seems to have the former two but not the latter. I wonder if it has carb adjustments or if the EPA emissions factor swayed them to omit that feature.
"IF" it uses the following engine it does have overhead valves, http://www.maxtool.com/us/products/XP7HP.asp but I can't tell from the pictures as there are slight differences, but since I see no Duromax 7HP that isn't OHV, it probably is.
Try to avoid using ethanol gas blends in equipment like this.
can you overnite this to north carolina?
