Yamaha EF2000iS Generators

Thanks for all the info looks like I’m going with the Yamaha 2000’s, I’ve got a 15000 btu ac unit and two parallel 2000’s should do it. I like to the 44 lb so I can move them in and out of the pickup bed without any struggle, they will be stored in a tool box just in front of the hitch. I’m going to do some NASCAR infield camping so I’m looking forward to my first dry camping.

Hi,

I'd look seriously at either twin Champion inverter generators, or the new 3100 watt Champion inverter generator.

Otherwise I'd go for the Yamaha 3000 SEB unit.

My 2400is will run my ac but it failed to restart it on one hot day in June a few years ago. Made rush trip to get Champion and have not used my Yamaha since for ac. Twin 2000's are a sure thing, 2400is is marginal.

I like how the Yamahas have a fuel petcock, which means that you can run the carb bowl dry for storage.

I love my Yamaha 2000is....could only afford one at the time, but will be buying the second when I need it. Presently, all our camping is at c/gs with electric hookups. Now, some day when we go off the grid, we'll get the second one.

I also did the research, and decided blue was better than red...and initially I was thinking red.

Weight, the EF3000 weighs 136 lb where the 2000 weighs 44. A little more money but very convenient.

but one EF240iS weighs 75 lbs and it will run microwave, etc. I am still trying to find out if it will start/run a 13,5 AC however. at 75lbs it is less than 2 x 44

I would take the Yamaha over the Honda if I were to do it all over again.

Here is some more info I had saved on comparison of the two brands.
Honda pros:
- ton of dealers, no lack of service or parts
- a lot of units in operation since they came out first
- fuel pump so it's easy to add a bulk fuel tank
- Honda has the guts to post how long the unit can run with a 2KW load (30 mins)
- 3 year warranty, consumer or commercial use - doesn't matter which.

Honda cons:
- WTH? no removable cylinder head!
- plastic camshaft with a single lobe that is timing belt driven (how long will this last being in contact with oil?)
- plastic oil slinger disintegrates after 7K - 15K hours. Engine fails shortly after
- aluminum cylinder bore
- cannot run the carb dry as the shutoff petcock kills the ignition too.


Yamaha pros:
- conventional construction, cast iron liner, removable cyl head, metal camshaft
- fuel level gauge
- fuel petcock doesn't kill the engine so you can run it dry

Yamaha cons:
- a LOT less dealers and service centers
- no mention of the 2KW rating on this generator anywhere

I have (2) Yamaha 2000. I love them. I did alot of research as I was interesed in buying the Honda as well. The reasons I choose the Yamaha are:
- The Yamaha has a fuel gauge.
- The Yamaha has a easy to access fuel shut off. (I have had fuel issues with the Honda 2000s).
- The Yamaha has a longer "rated" life
- The valve timing mechanisim was better on the Yamaha ( I forget now exactly what is was, Honda uses a belt.
Both are execellent machines and it took me some time and effort to decide, but I am happy with my choice. Check out Wise Sales online they have alot of information and are excellent to buy from.
As for using the generators I use the parrallel cables and run both units when using the AC (econo swithes off on both units) and if I don't need all that power I can run a single unit in econo mode and you can barely here it. One recomendation I have if you buy two units is get the hour meters I use the meters to equal out the run time.
