Topic: Yamaha EF2000iS Generators
Posted By: jimmac28 on 05/16/13 06:31am

I'm about to buy two Yamaha EF2000iS Generators, plus the parallel cable. Does anyone have any experience with this setup good or bad? Thanks.

Hi All.

I can't say anything at all about the Yamaha EF2000is Generators. Excetp for the fact that a Yahama is a very good brand of Generatores.

Howevre ever, we do own the "Red Ones". We have a Pair of Honda EU2000is', Paralla Kit and Extended Run Tank. If your Yahams runs anything like the Twined Hondea's EU2000is do, you willl be one very Happy RV"er.

Its great to have the opetion to run only one Generator to Recharge your Battery Bank, and still have power left over to runs some lights and TV and a few other small draw items.

With our twin Honda's, I easily ran our 13,500 BTU TT A/C, and the Frideg and the Microwave, all at the same time, and still have some power left over.

We sure are glade we keep our Twind Honda EU2000I;s. Paralla Kit, and Extended Run Tan when we sold our 5er. With our Motornhomes built-in 5.5 G Generator plus the Twin Honda's, we can easily go past our Motorhomes 30 AMP limit anytine we feel like it.

Its nice to have all the "Generator Power", that you would really ever need with us. But at the same time, its one thing for sure that we will never have to worry about, "Not Having Enought Generator Power" and then some.

They are also easy to move around and very easy to even store.

Good Luck. Happy Travels. Dan & Jill & our Yorkie Kids

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

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.

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

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 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.

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

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.

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.

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.

No, the Honda EU2000i has a cast-iron cylinder. The block is aluminum. You might be thinking of the EU1000i, which is indeed 100% all-aluminum.

Hi Robert,

Thanks for the "straight goods"

What I know of Yahama's comes from a sales rep. but, it's enough to convince me I want a 1200.. (Just enough to charge batteries with my PDI 9180+Wizard)

Home was where I park it. but alas the.

I had just purchased a new Honda 2000, ran great the first 8 hrs. Fired it up a week later, started running a little rough, (I'm in California by the way, ethanol in fuel). About 3:00 am the generator shut off!! In the morning I drained the tank, put Seafoam in, sputtered a while still but next day it was fine. Came home and ordered a 2nd to go with it so we can run everything's at once in RV. Figured rare issue. After googling it, there's lots of problems, even with new. I'm thinking it's the chit fuel in calif.

Anyway, yesterday we setup for the livermore rodeo and the bastard shut off!! Emailed Amazon and I'm sending it back, along with the one in the box I just received yesterday. I haven't read as many issues on fuel with the yamahas, just the neglect of letting has sit in it forever. The seller that uses Amazon said, start the return process. I was going to just exchange for the convienence but either way I'll have to drain oil and fuel.

Hondas do have a carb drain screw and the attached hose drain out to the bottom on one side.

The Honda's have an electrical connection beside the shut-off switch that, when disconnected, only shuts off the fuel allowing it to run the carb and lines dry.

I pulled the plug again and it's actually running lean, makes sense with stumbling. I cleaned the "muffler" out. Opened the screw drained the fuel out. Took air cleaner off, put some Seafoam in carb. Fired it up, still rough. I moved the on/off gas cap switch as I've read that it opens more half closed, didn't work. Only thing that smoothed it out is half choke. I've probably read 500 threads on this issue and only one other guy had that issue with half choke. He even took it to the dealer and they couldn't figure it out? It's cool in livermore this weekend so we don't need the ac and we have enough propane to run the fridge. Wife needs it on for coffee. I've read where guys do all this stuff, modifying, using jet fuel ! And draining after every weekend out?? This isn't an old Coleman here, it's a $1000 Honda. I'll take the inline filter off (find YouTube how to get to it). If it's clear, I'm not taking the carb off. If this was a year old or I didn't maintain it, I'd understand, It's not. If this doesn't work I'll be returning both.

Thanks

Do yourself a favour, drain the tank and carb, get a can of Seafoam. Pour about 2 ounces into the tank and open the petcock(on/off switch) and let it sit for a couple days without starting it. Drain the carb again then add some fresh gas. Seafoam will "eat" its way through the carb, dissolve the crud and open up all the little passages. It might smoke a bit on start up, but that will be normal.

Posted By: Hundo24 on 06/10/17 07:21pm

I'm ok with doing that, although I did empty the tank, run Seafoam through it. Ran great for 2 tank fulls, (2gal). Like I mentioned early, this seems to be a common issue, especially in California with **** fuel. Will see how it feel about this on Monday.

Thanks
