Q: I have a customer running propane on a Yamaha genset. While burning propane the engine burns excessive oil, not a problem on gasoline. Any ideas?
by Shane Bland from Florida on June 24, 2014

A: The Yamaha portable generators are engineered and warranted to operate on gasoline only. The reason your customer is burning through oil is due to the excessive temperatures of the unit.

Gasoline burns at 485 degrees F whereas propane burns at 1008 degrees F which will cause excessive heat within the engine in turn burning off the engine oil.


by Jared, Product Expert
Q: Can two of these be connected together? I need 3500 watts minimum to start my A/C unit.


by Jeff from California on October 16, 2013

A: Thanks for your inquiry.

The Yamaha High Current model is not compatible with parallel cables. We do offer the EF2000iS Parallel kit which will give you 4000 watts surge and 3200 watts running when using the 30-amp outlet. Below is a link to this kit.

by Ken from Kansas on May 08, 2013

A: You will find the oil recommendations on page 24 of the owner's manual....

Recommended Engine Oil:
A. YAMALUBE 4 (10W-40),
SAE 10W-30 or 10W-40

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.

by Jared, Product Expert
Q: Can we use the EF2400iSHC with an RV that only has a 30 amp or a 50 amp plug in?

by Mary Irish from Wisconsin on June 24, 2012

A: This model is too small for 50A output and in come cases it can be too small for 30A output.

This model is capable of producing 17A with a little surge capacity beyond that. It does have the capability of starting "Most" 13.5 BTU RV AC units when using a 20A power cord connected to a 30A RV connection with an adapter.

The EU3000ISEB is a better choice for output capacity and comfort due to its boost capacity and overall running capability.

Q: Is there a way to shut off the gas supply so I can run the carborator dry?
by Bill Garrett from Florida on June 24, 2012

A: Yes, all the Yamaha generators have a fuel valve shutoff allowing you to run the carb dry.

by Jared, Product Expert
Q: How does the EF2400ISHC run a 13,500 BTU air conditioners without a 30amp plungin?
by Larry Mitchell from Texas on June 15, 2012

A: You need to us a 20A cord that matches the 120V - 20A outlet to pull the maximum out of the generator.

by Jared, Product Expert
Q: Are there any good quality inverter generators with electronic ignition in the 3kw range or less?
by Rob from North Carolina on April 30, 2011

A: The Honda EU3000isA and the 2 Yamaha 2800 watt generators are electric start. Click the links below for additional info:

Small Inverter Generators

by Jared, Product Expert
Q: Will an inverter type generator be the right choice for running a sump pump that cuts in frequently? The pump is a 1/3 hp 9amp 115 volt. I currently have a 2500 watt porter cable (traditional) generator with Honda motor. I am looking at a Honda or Yamaha as a backup/replacement. I am unsure if I the EF2400 would be powerful enough for the regular and frequent start-ups.
by Geoff Winsor on January 20, 2011

A: The best thing to do is to calculate the starting amperage of the pump to find out what you need exactly. The formula to calculate wattage is - Starting Amps x Volts = Watts. Then you can determine the size that would suit your needs without purchasing something that may or may not work.

Electric Generators Direct Recommended

The 2000 watt high-current inverter generator from Yamaha is specifically designed to start stubborn, high surge electric motors such as those found on rooftop air conditioners. Until now, a person typically had to resort to a more expensive 3,000 watt inverter generator to muscle through this start-up load. Yamaha claims the new EF2400iSHC will successfully start and run most 13,500 BTU air units.

In addition to its brute starting strength, the EF2400iSHC features an economy mode for... more

Five Years And Running Strong
I first purchased this unit to use in my race trailer to power my roof top AC unit and run other power tools. I have put several hundred hrs on this unit without an issue. I do change the oil on a regular basis and i need to change the plug and air filter but it runs strong, always starts and is reliable. Can't ask for much more.
Pros: Quiet, High Quality, Reliable, Durable
Cons: Heavy

So Far So Good!
I bought the EF2400ISHC in hopes that it could power our 25' Airstream's 13,500 BTU air conditioner. It works! I needed a gen that was small, but I didn't want to have to go with 2 generators running in parallel (seemed like 2x the opportunity for problems). I know it can't run everything simultaneously, but that's not what I was going for. The EF2400ISHC started right out of the box on the 2nd pull. It's light enough for me to be able to pull out of the bed of the pickup, and easily fits under... more

I've changed the oil at 10 hrs. - will change again at 20 hrs. After that every 50 hrs. Going for longevity.

Yamaha 2400ishc 6 Month Review
I am writing this review about 6 months after purchasing and using the EF2400ish Yamaha generator with a total of 40 hrs on it now. I would recommend this generator and would buy one again.

Honestly this has been a great little machine that uses very little fuel. It runs my 13.5k Coleman mach 3 ac in 90+ outside temp's with no issues at all, for hours at a time. As a precaution I did install a hard start kit as a precaution and use a 20amp to 30 amp plug. I am using the recommended Yamalube... more

Excellent, Compact, And Comparatively Quiet Generator
I have just used this Yamaha generator for 12.5 hours and it has worked very well for my purposes. It is impressively quiet, has the additional startup current that similarly sized, pure sine, compact generators don't have, and holds enough fuel to get one through an average work day without having to refuel. The only minor situation I encountered when I first extracted the new generator from its packing material was that part of the casing or sound insulation panel was not properly aligned... more

The Ef2400ishc Runs My Ac Perfectly
My wife and I just became parents to a beautiful baby girl. We love the lake, and upgraded boats to something more baby friendly. It's a 32 ft pontoon boat with an enclosed wheelhouse. As part of the deal we had to add an AC to keep baby girl cool. To power the AC while out on the water, I purchased the Yamaha EF2400iSHC from Electric Generators Direct. Their shipping was *SUPER FAST* with the expedite option. The AC is a 13,5000 BTU Coleman Mach III Powersaver. The EF2400iSHC has no problem... more

Awesome Generator
I reviewed and searched for weeks before finally deciding to buy this one.

I plan to use it on the mobile BBQ truck I'm building. It will handle most of my needs for now.

I will probably buy an extension soon so I can run both a small a/c and the food warmer I have on board, but for now it will do the job.

It's very quiet and easy on the ears. I'd highly recommend it!!

I purchased a Yamaha 2400ishc generator after reading reviews stating that it would run a 13500 BTU Air conditioner."Buyers beware" (It will not!). I have a 2011 Surveyor which is still brand new. I called Electric Generators direct and they told me they could not help me. No Returns. So To all. make sure it's the generator you need and don't trust all reviews. No Returns!! Expensive mistake.

Ran 10 Hours Then Stopped Making Electricity
This generator ran for 10 hours then quit. I was told to take it to a Yamaha Service Center, which I did (80 miles away!) They found that a wire was loose on a circuit board, which they fixed. The gasoline shut-off lever also broke the first time I tried to use it. They replaced it with a new one. When I returned to pick up the 3 month-old generator, I was told that Yamaha refused to cover the repairs under warranty because the generator was not "registered." Not sure what this... more

Don,
I would suggest contacting Yamaha directly @ (800) 962-7926 for clarification. Your sales receipt should be all that you need for a warranty claim. When contacting Yamaha, please let them know the name and contact information of the service center you took your generator to.
