Yamaha EF2000iS Review

Why did consumers buy the Yamaha EF2000iS


Reviews are overwhelmingly positive for the Yamaha generator. Many people liked the fuel gage and the lightness of the unit. The gas gauge is especially enjoyed by reviewers. Reviewers enjoyed how easy it was to change the operating speed and how easy the starter cord is to pull.


Most reviewers said their favorite thing about the generator was how quiet the unit runs. One commenter said he ran the generator at full engine speed and he could stand six feet away and carry on a regular volume conversation. There is an eco-setting of the generator which also helps make it quieter. One reviewer said he completely forgot about it because it was so quiet on a lower setting. Another said it was quieter than his boat’s engine. Yet another generator user said he bought two because he loved them so much and let a fellow camper borrow one because his generator was extremely loud.


The power behind the generator is favored by reviewers as well. They enjoyed the ability to run heavy duty power tools off of the generator and said it was better than others like it. The Yamaha could run the heavy power tools on the eco setting, allowing the generator to run more efficiently and quieter than other models. When the power went out for one reviewer, the generator was able to run the refrigerator overnight in eco mode. The fuel burn rate is very low as well, so the Yamaha uses a fraction of what larger generators use.


The gas power is not a problem for those sensitive to fumes. While Yamaha says that the generator should be stored in a well-ventilated area, the odor from the fumes is nonexistent.


Are there reasons why you should not buy the Yamaha EF2000is Generator


The biggest complaint about the Yamaha was the oil level. The generator does not include engine oil, so users had to buy their own 4-stroke oil to fill the unit. Reviewers also said they needed a funnel and a pan to catch excess oil.However some reviewers loved the fact that Yamaha put a small drip tray underneath the opening to catch a lot of the excess.

Some users disliked how expensive they are, but reviewers argued against their complaints. Reviewers said the generators are constructed with a labor intensive method. Inverters are built to insulate and are tightly arranged in their cases. Insulation is why the generator is so quiet and favored among reviewers. The care put into the construction is part of what you will be paying for. The generator is also highly portable, thanks to the construction. This convenience and light weight are also part of the cost.

For common complaints about the generator, reviewers offered some tips. If the generator is sitting around, then it needs to be run periodically. One reviewer suggested running them once a month for ten minutes. This ensures the generator will start easily when it is used again. When transporting the generators, reviewers say you need to tie them down because they tip over easily. When you start them after falling over, they will have a lot of white smoke thanks to the oil burn. Ratchet tie downs are better than bungee cords.
