Great little generator. Review by Nathan
Quality

I did a pile of research before ordering the Yamaha 2000 over the Honda 2000. The only reason I went with the Yamaha was it was a little better value. A good friend of mine has the Honda and I can't say there is any difference in sound at all. Great Generator and Great Company to deal with. (Posted on 9/5/14)

I ordered the Yamaha 2000 watt generator from, Wise because I was leaving for a fishing/camping trip in 2 weeks. I accidently gave them the right street address but the wrong city and zip. ( recently moved, had the old address stuck in my head ) the day it was supposed to be delivered I realized what I had done. All it took was one phone call to Wise Sales and they fixed the problem and my generator was at my door two days later. My hat's off to the customer service Dept. at Wise for getting it to my door on time.
As far as the Yamaha goes, I'm brand loyal to neither Honda or Yamaha but after doing several hours of research on the Net, I found that the Yami is the one to go with. (Posted on 5/30/14)

After many weeks of a bitter winter, I finally decided to get a generator to use in case of a power outage. Upon recommendation of my brother-in-law, I opted for the Yamaha from Wise Equipment.

I just tested it out, cranked on the very first pull. Will run a fridge along with something else small. Takes everything she has to run a commercial bun coffee maker with both burners on, that was the biggest load I could put on it. Clean power, quit. I always recommend Yamaha for just about anything. I have a Honda pump, I love Honda, but comparing the 2000 watt models, the Yamaha has the advantage in features and construction. ***** It's quite, it's nice, but that 2000 watts goes fast ****** (Posted on 2/23/14)

Shipping was extremely fast. The folks at Wise are incredibly efficient. As for the generator, I love it, but since it is still new, time will be the real judge. It's light-weight and easy to operate. After testing with several items, such as fans , quartz heaters, blow dryers.. etc. I really love the way the engines ramps up according to current draw. Ultimately this will save me lots of gas, and at times of no draw it's almost silent. I should have bought this long ago. (Posted on 11/4/13)

Yamaha Generator 2000ISReview by Jeff
Quality

Did a ton of research on the Honda vs Yamaha. Found that the emmission compliance time for the Yamaha is two times longer than the Honda. The Yamaha also has a fuel gauge and the fuel drain, which Honda does not. Honda charges for the battery charging cable and Yamaha throws them in for free. Overall both are great generators but the Yamaha is more bang for your buck. When it arrived I put oil and gas in it and it fired right up. Wise shipped the unit well protected and it made it to me without a scratch. Thanks Wise! (Posted on 11/1/13)

This product was purchased after doing a ton of research and has been a great choice. I was torn between the Honda and the Yamaha as I assume we all are.

I have no complaints about this generator. It's easy to start and runs well. I did find it awkward to fill the oil reservoir. It's too bad that the cover has to be removed and the oil filled from an awkward angle. But, that aside, this is a tight machine. (Posted on 7/1/13)
The best purchase we've made for our RVReview by Reno Nevada Family
Quality
Value
I purchased the Yamaha ef200is over the Honda equivalent for a few reasons. Here's my reasoning.

Yamaha has a fuel gauge. Very nice when checking the fuel level in the dark
Yamaha has a separate shut off for fuel. Allows you to run the carb dry before you store it.
Yamaha has a shut off control on the fill cap. Eliminates fumes accumulating in the basement storage of our motorhome. Honda may have the same
Yamaha EPA certification period is 500 hours. Honda is 250. Most Chinese made knock offs are 125. This might be an attribute of the engine build tolerences.
Yamaha draws it's fresh air from the top of the generator housing, versus the Honda which draws from the bottom. If the generator is sitting on the ground directly this would be a nice benefit.

I can't say enough good about Wisesales folks. Shipping was fast, and the price was very fair. We absolutely love the generator and wouldn't hesitate to but anything else from Yamaha or Wisesales.

On a side note. I would recommend to anyone purchasing the generator. Purchase the screw in oil change oil change funnel. The headaches it will eliminate by making your oil changes easier is well worth the money spent. (Posted on 6/29/13)

I bought this unit just b/4 going on our camping trip to the high sierras early this month of June 2013. We were dry camping. I only started the unit a couple of times at home for about 10 minutes each time. Went camping and the only negative thing I can say about this unit is that the unit gave out very strong carbonmonoxide exhaust fumes and I could not run the unit for very long as it was fuming my campsite and my neighboring campers. So I don't know if possibly the altitude had something to do with it or what. We were at 6800 ft above sea level.

Defective out of the boxReview by Titanic

Received the Yamaha after considering both the Honda and Yamaha 2000 model generator. Liked the fuel shut-off, fuel quantity and battery charging cables on the Yamaha. I serviced the unit with oil, got it running, but it was always hard to start. Took it camping in Florida, our first night in the new camper and the generator died and would not restart just after dark. We went home the next morning and called Yamaha and they gave me a couple of numbers for local service centers. Called one and since it was quite a distance decided to do some trouble-shooting on my own. Pulled the brand new air filter ok. Pulled the plug and it seemed a bit fouled. Reinstalled and then pulled the exhaust spark arrestor. The screen was more than 60% blocked with what looked like yellow fiberglass insulation. Removed it and the machine started right up and now has about ten hours of first pull starts and trouble free service. Leaving for Yellowstone in 2 days! (Posted on 6/9/13)

Everything it promised to beReview by JW
Value

After struggling through hurricane Sandy with an underpowered generator which simply would not run my fridge and seeing the gas lines after it was over I had a long time to think about generator essentials.

I came up with a list of improvements for my Honda generator such as an inverter which would not constrain the unit to a fixed speed to mainatin frequency and provide clean power at varying speeds. When I was complete, guess what somebody had already done it! Having had to clean out the main jet and strip down the carburrettor as the storm was gaining momentum I don't need telling about the need to drain down after the unit has been used; this was one unit that had that feature. Surprisingly Honda Don't and you have to take off the covers to drain it.

When I got the unit I put about a pint of gas into it and it went third pull. The acid test was with the big fridge and it revved up as soon as the compressor kicked in, returned to normal speed and continued as if nothing had happened. It took a few minutes for the unit to die when I turned off the fuel and adding oil was messy but that was it. Don't tip it up when filling as it over fills and makes a mess everywhere. Better than the Honda in every respect; Honda make good engines but they need to catch up with these people and lower the price.

This is a good compromise between power and economy, the bigger cheaper genrators are great but if you can't get gas to put in them they are of no use! The real surprise is that at 44lb it is like a samll suitcase and can go with you on camping trips too! (Posted on 3/1/13)

Love it. Quiet enough to ignore from 20' away. During our recent 2 day outage, it just kept chugging away. Kenmore fridge + fan + computer + lamp. No problem. 8000 btu window air conditioner? A bit more of a challenge, would hack it in low speed with Econ mode off.

I would buy it again. Or maybe, I will buy another one so I can parallel them. I also have a big 10kW B&S generator, but didn't run that because it is too noisy (used it to power my tablesaw, etc, but that was it). (Posted on 7/2/12)

Excelent product for my application. I just got the generator to be use on my boat to power an Eight thounsand btu a/c plus a 60 amp batterie charger all at the same time. Well it did it and running the test I plugged in by mistake an 1500 watts cabin heater that also worked fine. I was imprest. The econo switch work fine but I did see a slow start when the a/c compressor went on, the blower dropped speed but for a couple of sec then the speed came back very strong. The rpm on the generator when up for no more than 5 sec and then drop to a lettle more than idle with the a/c running fine. A/c, Batterie Charger and a table fan all at the same time no problems at all for this little guy to power up. Life is good. I was looking for a generator with more power but this one seen to be doing the job. Good buy plus wise got it delivered at my front door in 3 days. (Posted on 5/16/12)

I bought the Yamaha ef2000is to replace a 3 week old honda eu2000 that i bought locally (i live in NY). The honda was blowing blue smoke on startup after roughly 5 hours of light use. Was getting worse with each startup. Oil level was correct (dealer set up unit) Took unit to two different dealers and both were telling me that it is normal?! Sold it in disgust for a loss and bought this Yamaha from wise. This generator is better in every way than the honda. Better features, just as quiet and powerful. Starts on first pull. Have around 20 hours on it at the moment and love it. Wish i had gone this route in the first place. Had bought Honda because all my friends have them. Now after they checked out my Yamaha they all said if they could do it again they would get the Yamaha. Highly recommend this unit and buying from wisesales. (Posted on 4/10/12)

Yamaha vs HondaReview by Donald

I have two Honda 2000's and have had them for 4 years each. I thought I would try a Yamaha based on these reviews. Wise took my order and shipped promptly. It was well packed and easy to unpack and easy to start. I took this generator to my hunt camp in Northern Ontario. It was cold there, around 0'F. The Yamaha starts easier than the Honda in cold weather
I put 30 hrs on the Yamaha before writing this. I added one of those inductive hour meters. It was very difficult to install compared to the Honda
The Yamaha seems to have a better finish than the Honda but I do not like the fact that you need a phillips screwdriver to remove two screws to get the cover off where the Honda utilized a coin. It is also tricky to snap the maintenance cover on and off after you have removed the screws. The screws on the Yamaha just fall out while the Honda screw uses a keeper so it won't fall away from the cover.
I found negligible difference in fuel consumption and noise between the two.

Now the problem. I have always used a Honda to power the cabin. I usually have the satellite TV running, a few lights, a fan. In the morning I run a coffee maker and toaster (at different times). While running the Yamaha with TV, lights and a fan running, If I started the toaster the TV would instantly go black as it would when the coffee maker was turned on. This NEVER happened with the Honda. It seems the Yamaha just doesn't have that quick ramp up power capability when a fast current draw comes on line.

If you are planning to add one of those magnetic dipsticks or extended range fuel caps available at Wise be aware that the threads are different on the Honda and Yamaha

This may or may not be important to you. There are other features mentioned above that the Honda has whereas the Yamaha doesn't have that may outweigh this shortfall

Yamaha EF2000iSReview by Ray
Quality
Value
Received my new EF2000iS within 4 days of ordering which was excellent. Unboxed, and followed the instructions by putting the oil in first, and then fuel. Unit fired up on the First Crank. This Generator Far Exceeds all others which are currently for sale, not only with muffled Sound, but also generator output. This light weight unit currently out performs my Kipor 3000 watt unit which I had been using with my RV, not only by weight, but 50% less sound. I would strongly recommend this Yamaha Unit above all others. (Posted on 1/7/12)
Completely SatisfiedReview by latonline

Fast shipping, all items factory sealed and fresh(brand new). Although the Honda was available I liked a few features and design characteristics of the Yamaha better. Nothing against either brand, I've ridden them both (heh, heh). If you had been looking for the EF2000iS in the past 60 days you would know it was in very short supply. I could have bought from a few other places, but early on I kind of became attached to Wise Sales - based solely on customer reviews. Don't usually rely too much on these, but I found very few negative reviews - other than some that just sounded like "personal issues". (Posted on 12/22/11)
Great Quality, great generator!Review by pvp64

After much research I chose this over the Honda. We just suffered through out the Nor'Easter in October 2011. Trees down everywhere roads closed for days and we lost power for 5 days. Generator performed flawlessly and was the only reason we were able to keep sane. Thanks to Yamaha, we had some heat and lights at night and a cup of coffee in the morning. Buying from Wise was a pleasure and they were very helpful and answered all my questions. I am going to purchase a second with connect cable. (Posted on 11/28/11)
It's quality,quiet, and a 3 year warrantyReview by Dallas
Value

It started on the first pull. It costs @100.00 more than a Honda because it has more features and a tool kit. I just hope it lasts for a long time. It is quiet,not heavy, and right now its works great. The reason I got a Yamaha over a Honda is because I read all the reviews for both online and the Yamaha had better reviews. I feel I made the right choice. I think $XXX.XX is too much for any generator this size but I don't want a piece of junk and this Yamaha is top-of-the-line. (Posted on 11/21/11)
Excellent product and sales experienceReview by Dan

I shopped for weeks for a reliable generator for football tailgating. For years the Honda was the undisputed leader for quality. After comparing the Yamaha to the Honda and Generac in real world all day SEC football tailgating in all weather conditions the Yamaha is clearly the best product/value. Wise was price competitive with excellent customer service and prompt shipping. We received the generator in three days brand new in excellent condition. Easy setup, easy start and very reliable and quiet. I love the fuel gauge on top. We are buying another from Wise. (Posted on 10/27/11)
"Just buy it' Review by Jimmy C.
Quality

I just got my EF2000is yamaha last week and just like everyone else, I added the fuel and oil, gave it a pull, and it started with just one pull. If you bother to do your homework, you'll find out that the run time is better and it has a few nice features that the Honda doesn't have. And yes, they are both "pricey". But like they say: "you get what you pay for". Don't bother considering the "mongruls that you can buy for less" try to have them fixed by someone you can trust if they develop a problem!
The bottom line: invest your money in something you can depend on with confidence and "just buy it". (Posted on 9/21/11)
Happy to have AC in my trailer, and back up for my homeReview by Affable One

Service and delivery were great. It arrived quickly, undamaged, ready to go. Fit, finish, quality. I added oil, gas, and first pull gave a pleasing, quiet, result. I tested it at home with skil saws, hair dryers, portable heaters,,, this is fun! Then it was off to trailer storage to test trailer AC. Yamaha's advertising say's "works with most 13,500btu air conditioners". I had trouble with my AC starting consistently until I found out that (brand) had left the start capacitor out of my AC. $25 part for the AC later and the AC works fine. Had it not worked, it wouldn't have been Yamaha's fault... to many variables in AC units. I'm a VERY happy customer. (Posted on 9/10/11)
Absolutely Awesome Portable GeneratorReview by Driller

I ordered this generator on 8/24/2011 in preparation for Hurricane Irene. It was delivered as promised on 8/27/2011, literally hours before the storm hit my area. I simply added the required oil and read the instructions on starting. One pull and it was purring like a cat. The unit once put into service, except for gassing up, ran constantly for approximately 48 hours without missing a beat. It ran my refrigerator and several other small appliances and lights primarily in eco mode without problem. It is great on gas and relatively quite, as advertised. I'm sold on the solid build of this Yamaha! I'm really glad I purchased it over the equivalent Honda since the Yamaha has more features such as a gas gauge and carburetor cut off, which are very important to me. Bottom line: Great product from a top shelf distributor. This was truly a WISE purchase! Thanks... (Posted on 8/30/11)

Great generatorReview by Rats

Ordered two with a series connector kit. They work great. Quiet powerful and very portable. They replaced an old Briggs generator. Wow what an improvement. They are more expensive than some other generators, but you really get what you pay for.

Delivery was fast. I had one small problem with the order and customer service fixed it at once. (Posted on 8/25/11)
California okayReview by randle

I ended up getting this unit over the Honda cause it's CARB Compliant and can be shipped to me. They're comparable in both sound and quality, though I'd probably have gone with the Honda if the CA price would have been better. Overall this Generator is solid. It even gets a bit better fuel economy than the EU which is always nice. (Posted on 8/13/11)
