Generator quieting

You are correct, it is a EM 3000. I thought that if someone had some success, they might share. I could and most likely will google but I thought my chances were better on this form.

Then I doubt it's an EU series genset as that's the designation Honda uses for their variable speed inverter series. With an open frame synchronous genset such as you describe about the best you could do to control the racket is mount it in a box, preferably lined with noise control barrier, and equipped with a large cooling fan that will move a lot of air across the engine and force it out through a large vent on the opposite side. These are pretty elementary designs, plenty of which can be found with a Google search.

I cannot find a HOnda EU 3000 non inverter generator. If it is an older construction type generator it is going to be very difficult to quiet down.

Doable, but I would not bother trying. Jim

Here in Canada there are two Honda 3K models, one known as the EU3000iS which is the class leader in "quiet" inverter gensets and the EU3000iK (known as the Handi in the US) which isn't the same at all and is significantly noisier. If yours is the latter I can understand why you'd want to quiet it down, the former not so much. I built a Generator Quiet Box for my own EU2000i but for a 3K genset it would have to be quite a bit larger and I suspect a handful to move around. Although I fashioned my own exhaust bezel you'd certainly find it easier to design a box by first replacing the 3K's exhaust bezel with this one from Generator Line. For lining the interior of the box I used Reflectix for economic reasons but you'd achieve far better results using a noise control barrier such as this from West Marine. Done correctly, to achieve maximum results, this won't be inexpensive. ;)

Might be tuff. I thought the Honda 3000 is one of the quietest generators available?
Maybe an insulated box?
