Quietly powers a wider range of applications for an extended time, while still portable and retro-cool.


  • Light weight — Easy transport
  • Compact — 2.2 cu.ft. size is easy to store and transport
  • Twin Tech (Parallel generator operation) - The EF2000iSv2 can be operated in parallel to deliver up to 30 amps.
  • Parallel generator operation - The EF2000iSv2 may be connected in parallel with an earlier model Yamaha EF2000iS.*
  • New controller with advanced programming - The addition of the new programming allows the EF2000iSv2 the ability to power a much wider range of applications than previous generation EF2000iS.
  • Smart Throttle varies engine speed based on load — Improves fuel economy and reduces noise. Runs up to 10.5 hours at ¼ rated load on a tank of gas.
  • Gasoline petcock - lets you shut off the gas to run the carb dry for storage and helps prevent stale gas problems.
  • Fuel gauge — See fuel gauge at-a-glance
  • Inverter system with Pulse Width Modulation (PWM) control — Produces a pure sine wave to run products with built-in microcomputers or microcomputer-controlled electric tools
  • OHV engine with cast iron cylinder liner — Efficient, reliable, powerful providing long life and excellent heat dissipation
  • OHV engine — Includes steel camshaft and valve train components
  • EPA & CARB Emission Engine Durability Rating — Yamaha generators have the longest emission engine durability ratings issued by the Environmental Protection Agency and the California Air Resources Board
