Re: ef3000iSEB: fluctuating engine speed in economy mode w/no load

 Let me know if the controller (board) repair works. My information suggests their has been a problem in this area for sometime. Yamaha of america techs when contacted (must be authorized dealer) recomend changing the speed control board with very little discussion. Been told new board is of a different design. Please be advised that this all second hand information. After much ado my ef3000iSEB seems to run just fine, however econ rpm seems higher than I remember.  Good Luck.       B
