Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board.
Gasoline petcock lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
Fuel gauge allows fuel level to be seen at-a-glance.
The EF2000iS is powerful, portable and retro-modern and delivers maximum output with minimum effort. It weighs a mere 44 compact pounds, making it easy to transport.
The EF2000iS is fitted with Yamaha’s most technologically sophisticated muffler. It’s so quiet that you can have a conversation near one and may not realize it is running. (51.5 dBA to 61 dBA – ¼ rated to rated load).
It is very compact (2.2 cu.ft.) which makes it easy to store and transport.
If you need extra juice, the EF2000iS has you covered — a convenient parallel function lets you connect two generators to deliver up to 25 rated amps.
Meets even strict California Air Resources Board and Environmental Protection Agency standards for low emissions.
Yamaha’s Oil Watch Warning System helps prevent engine damage from low oil and provides added peace of mind.
