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.

Q: Can I run an electric dryer (4 wire), and nothing else at the same time, using the l14-30r plug on the Yamaha EF6300iSDE and an appropriate extension cord such as I might find at Home Depot?
by Tracey Bowen from New Mexico on September 16, 2013

A: Thank you for your Inquiry!

The Yamaha, EF6300ISDE is rated to produce, 23 amps at 240 volts. It is likely that this unit can support your electric dryer, however you will need to determine the starting amperage of that appliance in order to be certain. You can find this information printed on the serial label of your dryer.

Also, we recommend using heavy gauge extension cords to connect heavy electronics. You can find these locally, or on our site as well....

Q: Is there a recommended way I can direct the exhaust while using my Yamaha generator in a shed? I built the shed specifically for the the generator so It can be used in the rain and snow.
by Gerald Barben from Pennsylvania on August 19, 2013

A: We do not offer or recommend any extended exhaust for portable generators. They are required to be run outdoors as they are air cooled and require proper air flow for engine cooling and exhaust.

The following GenTent is recommended for use with the Yamaha EF generators but also requires a PVC frame for support....see links below....

Q: Is it possible to run the yamaha EF6300iSDE on propane or natural gas? I have seen some kits but not sure if the engine is actually made for it. thanks
by Joe from Connecticut on February 08, 2013

A: 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.

We do not recommend altering the generators we offer to a different fuel type other then what they were engineered and designed for.

by Jared, Product Expert
Q: This Generator appears to be much more enclosed than usual. Does it require a cover for rain or snowy weather?
by Bill from New York on January 06, 2013

A: Yes, this unit does require a cover for wet weather as it is not water tight.

by Jared, Product Expert
Q: Are these quite running generators for like camping?
by Amy Braaten from Minnesota on July 31, 2012

A: Yes, the inverter style generators meet all the National Forestry requirements for noise levels.

by Jared, Product Expert
Q: Is the warranty on this product a factory warranty from Yamaha?
by Paul Turcotte from Maine on June 26, 2012

A: Yes, you get the full manufacturers warranty which would be covered by any local Yamaha service center that works on generators.

You can find the local service centers by clicking on the following link...

Electric Generators Direct Recommended

Yamaha is one of the only manufacturers to offer a 5500 Watt inverter generator.

We recommend the EF6300iS because of the "Inverter Technology", it's not your average 5500 Watt portable generator. Basically, it has the ability to generate clean power to run sensitive electronics and the extra wattage will be able to run most 15,000 BTU RV A/C Units.

Yamaha has been manufacturing quality power equipment for a long time, you can't go wrong with this inverter.

Outstanding Inverter Generator!
I bought this for our mobile boutique and wanted something semi-quiet for use during vendor events. This handles my AC unit and all other power requirements with ease!

"I had a very bad experience with Cabela's ordering the same unit ( they sent me the 4500). When I called your customer support they said it may ship about a week after I ordered it since it was factory direct. The next thing i know I received an email saying it was shipped and recieved it within the week! (Cabela's took 12 days) It was amazing and I will recommend everyone I talk to about ordering it here."

Love My New Generator! Quiet, Easy Start, Powerful
Wanted a Honda, but needed one to fit a specific spot in trailer....this one was the perfect size and I love it. I am so glad I found the Yamaha brand. My husband added straps to the lift ends, and two solid wood poles, make it easy to lift in and out of the trailer.
Pros: Quiet, Reliable, I'd Buy It Again, Fast
Cons: Heavy

Could Use Caster Wheels
This generator has four straight-axle mounted wheels. Two on one end need to be castered. As is, to turn when moving from place to place you have to pick up one end and move it sideways.

The screws securing the side panels need to be captive. They are lost screws waiting to happen.

The unit starts easily and runs quietly.

Great For Our Rv
We used this generator with our 34 ft RV, it ran two 15,000 btu AC units and we had lights, water pump etc. very impressed! It used 4.5 gals of fuel in 6 hours on economy and kept the RV at 69' in 102' weather. It's quiet and looks great, only issues are its heavy, especailly if you have to lift it in and out of the truck, and it can't be used in the rain!
Pros: Easy To Use, Quiet, High Quality, I'd Buy It Again
Cons: Heavy, Expensive

Great Product But Has Mobility Issues
I have this model and it works as advertised - which is it's great product. My issue is with the wheels. They are fixed and that means they do not swivel which (also) means if you need to change direction of where you're pushing, you need to pick up one end or at least drag one end sideways. It weighs 200+ pounds so that's no easy task especially for the ladies... I've made this feedback available to Yamaha (in 2012) and they did not seem to care...

I'm considering putting it on a dolly... more
