Q: I was interested in buying the Generac GP17500E. I did my homework and believe it is the one for me. The questions I have are:

1. Can I convert it to propane?

2. How long will a 15lb propane tank last on this generator if I'm not powering the whole house and just the bare necessities?

Thank you Ryan

by Ryan from New York on October 16, 2013

A: Thanks for your inquiry.

We at Power Equipment Direct do not recommend converting your gasoline portable generator to an alternative fuel and doing so will void the manufacturer’s warranty and may cause damage to the generator itself. These conversions are not recommended by any of the generator manufacturers.

Gasoline has an Ignition Point of 475–536 °F. When a generator is manufactured to run solely on gasoline these temperatures are taken into consideration and the engine components are made to handle these temperatures.

Propane (LP) has an Ignition Point of 920-1020°F and Natural Gas (NG) has an Ignition Point of 900–1500°F. These higher temperatures will cause damage over time on any “gas only” powered engine.

The following guidelines cover Honda engines (Also applies to other engine manufacturers) modified to run on fuels other than the one for which they were designed, such as converting an engine to run on propane (LP) or natural gas (NG).


• Honda gasoline engines are certified to operate on unleaded fuel with a pump octane rating of 86 or higher, containing no more than 10% ethanol (E10).

• Any change to the original configuration of a certified Honda engine is a potential violation of the Clean Air Act prohibition against tampering (40 CFR §1068.101(b)(1)). The tampering prohibition is important because poorly designed and installed modifications can increase emissions.

• The Clean Air Act prohibits anyone from removing or rendering inoperative any device or design element installed on engines in compliance with regulations. These actions are considered tampering, which carries a civil penalty up to $37,500 for each engine or equipment in violation.

• Engines converted by a third party (OEM, dealer, converter, etc.) to run on a different fuel type must be recertified with the EPA on the new fuel to comply with applicable emission standards. The third party must recertify under a new family and notify Honda to not include the modified engines in the original family.

• Converted engines to be sold for use in California must meet CARB requirements and the converter must obtain approval from CARB. EPA certificates or tampering exemptions will not satisfy the requirement for CARB certification.

• Once certified, the third party must remove the Honda emission control label and apply a compliant emission control label for the new fuel indicating the new certifying manufacturer. Honda will no longer assume any responsibility as the certifying manufacturer.

• The Honda Distributor's Limited Warranty does not extend to parts affected or damaged by the conversion to or use of fuel other than the fuel for which the engine was originally designed.


• Honda offers V-twin engines specifically designed and certified for use in LP/NG applications. The engines incorporate special design features that address the higher combustion temperatures and reduced lubrication to the valve guide area (since it is a dry fuel, not liquid). Please contact your sales representative or distributor for additional information.


Disclaimer: The guidance provided is intended for Honda dealer/distributor informational purposes only and not for the purpose of providing legal advice. You must contact the appropriate certifying agencies if you require information on how regulations apply to your specific application.

The regulations and additional information can be found at these web sites:

EPA - EPA

CARB - CARB


The run times will always vary based on the actual load put on the generator.

Q: Is the Yamaha 1000is generator USFS compliant?
I want to use on forest service land.
Spark arrestor etc.?
Ditto for the 2000 model.

Thank you

by Don from Washington on October 09, 2013

A: Thank you for your inquiry....

Yes, the Yamaha inverter generators meet all USFS requirements and they all include spark arresters.

Q: I just ordered a Yamaha 2000 generator. What type of oil do you recommend? Preferrably an oil I can buy anywhere. Synthetic vs. traditional? 10w-40?

A: Thank you for your inquiry.....

Per the owner's manual (Page 28), available on our site under the specs tab, list the following:
Recommended engine oil:
A. Yamalube 4 (10W40)
SAE 10W30 or 10W40
B. SAE #30
C. SAE #20
D. SAE 10W
Recommended engine oil grade:
API Service SE type or higher
Engine Oil Quantity:
0.4 L (0.42 US qt., 0.35 lmp qt.)

Q: Do you recommend conversion to Propane for the Yamaha EF2000iS? And which fuel, gasoline or propane gets the most 'bang' for the buck?
by LYLE ARAKAKI from Hawaii on May 11, 2013

A: In regards to your question, the Yamaha generators are engineered and designed to operate on gasoline only and they do not have a specific conversion kit. We recommend using gasoline only because if you use a different fuel type you will void the warranty.

With these units designed and engineered to operate on gasoline, which has an ignition temperature of 485 F and Propane/Natural Gas has an ignition temperature of 1008 F, by changing the fuel type that over time you can easily damage the internal components of the engine and shorten the life of the unit.

by Mike, Product Expert
Q: Can you recommend a Transfer Kit for this Generator?
I would need an Inlet Box as well.

by GH from Maryland on February 07, 2013

A: The following switch is the best recommendation for use with the Yamaha EF2000iS which only produces 120V so the switch will only handle 120V.

Model 15114A

The switch comes with a standard 15A outlet but if you need to have an outdoor inlet box then the following model would be the correct one...

Model PB15

Q: What is a inverter generator?
by Francine Breland from New Jersey on December 28, 2012

A: An inverter generator is a power generator that can process raw power into a power feed similar to the power received through power lines. The generator part of an inverter generator is usually powered by gasoline or diesel fuel. "Inverter" means that the power is converted from direct current (DC) into alternating current (AC).

Typically inverter generators are much smaller then standard open frame style generators and tend to operate at very low noise levels. This makes them perfect for tailgating or camping and in some cases able to power one or two items in your home in an emergency.

Q: I am looking at the Yamaha 2kw to power a small 5000 btu a/c on a boat. I have read several reviews that the Yamaha can power it...would you agree?
by Steve from Florida on September 12, 2012

A: The average 5000 BTU AC unit can require an estimated 1300 - 1600 watts at start-up so based on that it should be able to handle it.

However, the only true way to tell is to find out the starting amperage and calculate it using Ohms Law...

Starting Amps x Volts = Watts

by Mike, Product Expert
Q: We have a high efficiency Triangle Tube boiler that was installed 2 years ago. According to my plumber my 30 year old Honda generator is the reason the boiler's electronic switch would not turn on during a recent power outage. I never had a problem with the 30 year old boiler that the new one replaced. Is my plumber correct?
by Steve from Alaska on September 11, 2012

A: Probably. I have a Triangle Tube boiler in my home for radiant floor heating & had to factor in the controller on it, as well as the high efficiency furnace, when putting in my new generator. These new solid state controllers are sensitive to voltage and harmonics. If either aren't within the design specs of the board the controllers wont recognize the power from the generator.

The key is to oversize the generator and ensure that the new generator has greater voltage regulation capabilities and cleaner waveform. These weren't requirements 30 years ago and your Honda of that era probably served you well. For today, you would have to replace the generator with a newer model.

If you had a 5kW Honda in the past (guessing) then a new EU6500 would be an ideal upgrade. You could also explore an automatic standby unit as they will have clean power and tight voltage regulation as well. If you need help choosing a new generator, please give us a call. We can help you navigate thru the options.

Q: I am looking to purchase the 2000iS and need to know what adapter to use to plug into my 30 amp TT?

by Josie from Arizona on August 22, 2012

A: Since this generator has standard 20A outlets you would want to use the following adapter...

Q: I want to get 2 Yamaha 2000 watt generators to run together. Are there 2 different generators or at they the same generators? These need to be wired together to double their power. What are the part numbers I need to get the 4000 watt capacity?
by Al Watson from Utah on June 23, 2012

A: You would get 2 of the EF2000iS generators along with the Reliance Controls Sidewinder parallel cable if you are connecting to your RV cord.

If you are connecting to a manual transfer switch in your home you would want the Yamaha Twin Tech parallel cable instead since it has a 30A twist lock connection instead of the 30A RV connection.

by Mike, Product Expert
Q: Jim, We just bought a 24' Rinker cabin boat, and would like to use this generator for our air. what are your thoughts on that? Is it safe?
by Audrey Johnston from Missouri on June 07, 2012

A: Unfortunately, the EF2000iS will not be large enough to run you RV AC unit. A typical 13,500 BTU AC unit requires approximately 2800 watts at start-up.

You would be able to do it if you purchase another one and then parallel them together with a parallel cord. This will provide you with enough starting wattage to start and run your AC and some other conveniences in the RV.

I would recommend the Sidewinder cable as the perfect cord to use when paralleling the Yamaha units.

Your other option would be to go with a larger inverter generator like the Yamaha EF2800iSE or the boost model if you just want to have one unit.

Any of the inverter models are safe to use and extremely quiet and meet all National Forestry regulations for noise levels.
by Mike, Product Expert
Q: Can you connect two EF2000iS generators and make a 4000 watt generator? If you can, do you have an RV adapter to connect the generators and connect your RV?
by Bobby Walters from Texas on February 07, 2012

A: You can parallel 2 of the EF2000iS Yamaha portable inverter generators. The following Reliance Controls Sidewinder parallel cable has a RV connection.

Q: Does the Yamaha 2000inverter generator warranty cover parts and labor for three years? It's for camping use, not commercial. Thanks
by John Miller from New York on January 26, 2011

A: This model Yamaha generator has a 3 year consumer warranty which would cover recreational/camping use. The owner's manual lists the fill limited warranty which you can review on our site.

The lightweight, fuel-efficient Yamaha EF2000iS inverter generator provides a practical, versatile machine that can go anywhere with ease.

No need to power up the big onboard generator – you can run your little EF2000iS all night long on less than a gallon of gas.

Yamaha is the only inverter generator we offer on our site that is rated as "extended" with a 500 hour engine life. All others are rated at 250 or even 125 hours. This engine life rating does not mean the engine will... more

Fantastic Generator
This unit is Fantastic, All of the other reviews have summed it up.

I like it so much that I put together an in depth video that talks about my generator, how to find out how much wattage you need and how to choose a generator that's right for you. It was all of the information that I wish I had when I was doing the research that it looks like your doing right now.

Good Luck!

Do Not Rely On It
I purchased this Yamaha gasoline powered unit as an extra to my Generac propane powered home back up portable generator, and for possible use on camping trips. This Yamaha has all of the important generator attributes.

Practically, however, out of the box, it was a disaster. After following instructions diligently, and after warmed up, the unit continued to spit, sputter and quit under load.

The last thing to check, tomorrow, is the spark plug gap. Even if that turns out to be the... more
Pros: Quiet
Cons: Expensive, Unreliable
Mike, the Portable Generator Expert
Product Expert
Howard,
Typically, an engine that will spit and sputter can be contributed to stale gasoline. You always need to use fresh fuel. Any gasoline/ethanol blend should be no more than 10% ethanol. This is extremely important on the East Coast because some stations have gasoline with 15% ethanol, which is fine for cars, but horrible for small engines.

Otherwise, if you're still having problems, you may want to take your generator to a Yamaha service center because it is covered by a 3-Year Warranty. Yamaha can be contacted directly @ (800) 962-7926

Are You Not Sure Between Honda Or Yamaha?
I was not sure between the HONDA or the YAMAHA until i did all the home work on it like your doing. The Honda seams to be the one to beat, and the YAMAHA DID IT! On you tube people start the Honda with up to 10 hard pulls, with the Yamaha I saw people start it with only 1 wimpy pull. You can also shut off the gas while the power is still on, so the gas thats still in the lines can burn out to keep the system clean. Honda can't do that. The motor is twice as good as the Honda for showing the... more

Carl,
This Yamaha and the comparable Honda model have a very similar db(A) rating. There really shouldn't be any noticeable difference in the sound each generator is creating unless one of the units is running on an "Eco" mode and the other isn't or one has a full load on it and the other has a smaller load. Like any other engine, you many notice a slightly lower noise output after the initial break-in period.

Shhhh!!!!!!!! Don't Wake The Generator
I purchased this Yamaha EF2000IS as a replacement for a Briggs & Stratton unit that was stolen from my boat. I can honestly say now that I am happy the old unit was stolen. This unit is everything that I thought it would be and more. The biggest thing for me was the noise factor. I ordered this online and the delivery was exactly as promised. I then put this unit (still in a sealed box) and put in on two flights overseas.

Wife Says Its A Keeper!
I had several points that had to be met before making a purchase. The unit had to be fuel efficient, quiet, lightweight and powerful enough to run a 8000 BTU portable air conditioner and a medical unit.

I had a hard time convincing my wife to buy another generator after investing almost $3000.00 in other brands that now sit in my workshop collecting dust.

Our love of camping has been on hold for 3 years. Every generator we tried was either too loud, too bulky or too heavy to lift.

I first used this at my boat dock to power the vacuum cleaner since there are no outlets there. I had the first of several conversations that go like this, "Nice generator, how much did it cost?." "Over $900.00", I said. Then they say the same thing that kept me from buying a generator in the past, "Oh, I could buy 5000 watts for $500.00."

The One Pull Start
After taking the generator out of the box & reading the directions. Filled it with oil & gas. It started on the first pull. I have used it 4-5 times since & it has started with 1 pull. The last time it was used it replaced a 3000 comm. gen. that would not start on a job site. It ran all day running saws, drills etc. all day long on 1 tank of gas. Its just a great generator & in this case you get what you pay for.

I use this generator mostly on the boat since it's easy to carry, store, and use. It's dependable and it's low fuel consumption mode allows it to run most of the night without refills. It can power my AC and most low voltage appliances. I choose this model over the similar Honda model because it had a fuel gauge, better reviews and price points.
