I have the Yamaha EF2000iS. I just happen to find it on line for $830 back in 1/10. It was drop shipped from the factory in WA. According to the specs, it is ~2db quieter and 2 lbs lighter than the Honda. With the right cord, it has the ability to be duplexed for a 4000wt rating. I can run my microwave with it.

Proper sound engineering is needed to reduce the sound of any generator. Sound can travel backwards through the air inlet unless it is properly baffled. Then you also ahve to remove the exhaust from the "box".

And why would you need to further quieten a EU1000i? They are pretty darn quiet to begine with.

Best pricing I found on the Honda generators was at Wise Equipment on their internet site.

I neglected to mention that the Hondas can be duplexed for 4 KW of power. There's a cable you use to connect them together. If you decide on a Honda try Mayberrys in NJ first. They had the best price I could find several years ago. It was just under $1000 with free delivery.

I have a generac genny in my coach that's pretty loud. Has anyone replaced the installed genny with a pair of the quiet hondas or yamahas and made them a permanent install with a fuel line from the coach's tank?

The propane Generac on my 5er got pretty loud when the exhaust pipe broke off near the manifold. Propped it up with some wood and made it though the weekend.

I'm interested in an answer from someone on this also.

The problem in mounting the EU200i hondas in a permanante install is the venting of the air inlet, air outlet and exhaust.

What we do on our 5er is to store the Honda pair in the are that notmally houses the Onan generator on the trailer. I lift the generators out and set them on the ground and hook up a plug to the trailer and we are good to go. I also keep the 6 gallon extended run tank in that compartment.

The Honda EU2000s are manual start which could be somewhat inconvenient while underway anyhow. On the other hand, Honda makes a 3000 watt generator that is not only electric start but also has the option of a wireless remote starter. Its the Honda EU3000iS Generator and is just as quiet as their EU2000.

If you want to run an EU3000i while on the road in your motorhome, best bet is to make a mount in the back bumper and run a power cable back there.

Marty,

Onan does make several quiet generators. We have a QD 7500 in our motorhome and it is pretty darn quiet after I did some additional sound deadening work. It is quiet enough that when DW is through using it for the convection oven when we are boondocking she usually forgets to turn it off because she can't hear it running (-:

To the poster that was concerned my Honda EU 1000i might overheat in its box. No problem I designed it so it wouldn't. It is now over 1200 hours and still going strong. I have a picture but Photobucket is screwed up and I can't get logged in to their site.

Jim

I'm the OP on this and I appreciate everyone's reply's. Good stuff for sure. Here's a friendly tip for others with the noisey Onans like me. Put some kind of sound deadening material directly beneath it when you're set up. It won't do anything to quiet the sound inside of the coach, but the sound outside is deadened a fair amount. I discovered this on our last season of tailgating. We're set up in a parking lot at the University and the sound bounces off of the pavement. I threw a rubber backed carpet mat under in and it made a big improvement. The kind of heavy mat the uniform companies rent. They work great. I later bunched up the mat to create ripples and it worked even better.

I have a whole stack of the carpet tiles like they use on raised floors in office buildings. I park in sand, but it does help a little when place below my 5500 Onan.

I've heard the Honda gets it's fresh air from the bottom and it is a good idea to sit it on plywood while on dirt. My Yammy gets it's air from the ends, but I still sit it on plywood.

I also machined a 3" extension, used the stock clamp to mounted it and put a Briggs and Stratton screw-on lawn mower muffler on the end. Lowered the dbs a little.
