Key Features:
  • The EF4000DE/D are the “all-star utility infielders” of the Yamaha generator team. They do everything well, quietly, efficiently, and still have power in reserve. The EF4000DE/D have the Yamaha 357cc OHV engine with a unique combustion chamber design that enhances power output and efficiency.
  • For those who want the power and glory of electric starting*, there’s the push-button start EF4000DE with all the same features and specs as the manual-start EF4000D.
  • Thanks to its extra-large fuel tank, the EF4000DE/D can run continuously for 8.2 hours at rated load without refueling.
  • The EF4000DE has the convenience of electric starting*.
  • Full power, full time 120/240 dual voltage which allows you to run multiple appliances that require 120 or 240 voltage making it highly versatile.
  • Yamaha’s Oil Watch warning system prevents engine damage, avoiding costly repairs and minimizing down time.
Features
