2014 Yamaha EF5200DE





Less Noise, More Juice.

With 5200 watts of peak power, electric start, dual voltage, Thermal Breakers Circuitry, Brushless Alternator, and an Oil Watch Warning System, the EF5200 represents one of the best values in generator industry.

Key Features
  • The EF5200DE/D models fit perfectly between the EF4000DE/D and the EF6600DE/D, delivering an unbeatable combination of power and performance. ... all in a quiet, compact design. They are ideal at a remote site, or providing backup power at home.
  • For those who want the power and glory of electric starting, there's the push-button start EF5200DE with all the same features and specs as the manual-start EF5200D. (Battery not included)
  • The heart of the EF5200DE/D models are a muscular 357cc overhead valve engine that can run continuously for 7.4 hours at rated load on a single tank of gas.
  • The EF52000 models feature 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.
  • Full power, full time 120/240 dual voltage - Highly versatile.
  • OHV engine - Improved efficiency, increased reliability, quieter operation.
