Q: What does ECON stand for on the switch? While running the generator what position should if be in?

Thanks
Mark

by Mark Babin from Louisiana on February 08, 2012

A: ECON stands for Economy mode and the generator will alter the engine RPM based on the load on the unit giving it a quieter output and use less fuel.

The standard running mode keeps the unit running at top RPM for heavy loads keeping the output at its highest.

Q: How much oil does the Yamaha EF1000IS hold?
by Anonymous on April 21, 2011

A: The Yamaha EF1000IS holds 0.34 quart oil.
by Jim, Product Expert

Q: I am buying a Yamaha 1000is from you. If I plan to not use the generator for a period of 4 months, so I just have to use Sta-Bil in the fuel and I am fine? Or do you recommend a draining procedure between uses, or some other kind of procedure?

by Mitch Carter from California on January 24, 2011

A: We definitely recommend the use of Sta-Bil fuel stabilizer in your generator as it will keep your fuel fresh for up to 2 years. We do recommend that you start the generator once a month to lubricate the internal parts in the system and also throw a small load on it to verify good operation.

Jim's Recommendation

We recommended Coleman Powermate camping generators for years.

Now, those little Mega Pulse generators are equivalent to dial-up Internet service.

New Inverter technology is making the traditional camping generator obsolete. They are smaller, quieter and produce cleaner electricity. Until now, they've been expensive too.

Yamaha is one of the best when it comes to inverter generators. Consider this little 900 watt version as the "broadband" of new camping generators.

Yamaha Inverter Generator

Purchased the generator to run my cellar "sump pump" in the event of lost electricity. Although I have not used it for any extended period, it was easy to set up and run and is not loud. It started up with 1 or 2 pulls. The only complaint I have is the positioning of the oil cap. It is on the "side" of the unit and that makes it difficult to fill without spilling oil. It also makes it difficult to determine when it is full. If it could have been placed on the top, then it could also include a "dip stick" to be certain you have enough oil. Otherwise, the unit appears well made.

This little guy is terrific in a crunch!

I bought this generator to power a blender and a fan before Jimmy Buffett concerts. Little did I know how handy it would be when we lost power in the Midwest for 8 days!

I would fill the tank, give it a couple pulls, and it would run my refrigerator (and a fan at night) for 8 hours. I would let it cool off for a couple of hours, fill it back up with gas, and run it some more. It never let me down.

We even used it to charge our battery back-up so we could watch the Steelers-Browns game. The fridge had to fend for itself for a couple of hours, but it was worth it!

Very nice unit and runs as adverised, but seems loader than the Honda unit which specs at the same decibles.

Still relatively quiet and reliable. I have had it for almost a year now.

Yamaha EF1000iS - 900 Watt Inverter Generator Review

I got this generator two years ago when my wife was put on a C-PAP for her sleeping disorder. I knew her machine was computerised and we would need clean power to run it.
I first looked at the Honda 1000 watt inverter and was seriously considering it, but I decided to do a little comparing of the different brands first. I'm glad I did! The Yamaha blows the Honda out of the water, longer run time less noise, engine runs at a much slower speed and the 12 volt DC cables are included. They cost extra on the Honda.
I could get the honda from my employer at a discount but it still co... more

Yamaha EF1000iS - 900 Watt Inverter Generator Review

My Yamaha 1000i is the only one of it's type in my sailing club. Everyone else has a Honda. The Yanaha is by my follow sailing club members the LEAST noisy gernator in the club. We cruise often, and usually use generators to power AC accessories. My Yanaha uses far less fuel than the Honda's, and produces quite a bit less niose. This is especially true when the load is less than 75% of maximum. At full output, the Yamaha and Honda's are about the same noise level, with the Yamaha slightly lower. At 50% oputput, the Yamaha produces considerably less noise than the Honda's.
Best,

Yamaha EF1000iS - 900 Watt Inverter Generator Review

I purchase my Yamaha January 2005 andicipating the upcoming hurricane season. I live in South Florida and boy I am glad I made the purchase.

This little baby ran my 32" Sharp LCD tv, cable box, dvd player, notbook computer, internet & wireless router, 1 ceiling fan and my 18 cu/ft refrigerator. All while sipping on gas.

Best yet, it is quite as a curch mouse. All my neighbors were wondering why I had power. It served me well through both Katrina and Wilma.

It can literally run many days on 5 gallons of gas. It cost me pennies to... more

Yamaha EF1000iS - 900 Watt Inverter Generator Review

An absolutely amazing machine. This is the smallest, quietest, most gas-frugal generator you should ever consider for home standby use. Consider that the normal generator that you buy at a home improvement store is terribly loud and can drink up to one gallon an hour even with only a partial load. At $3 per gallon, that could be $500 per week! Now the EF1000is has much less capacity than those other generators, but if you are willing to live within its limitations, you will have a sewing-machine hum rather than a Briggs&Straton roar and a 5 gallon can of gas will last you for days... more
