I have a 2009 200HO Evinrude Etec.  I just installed the i-command gauge and connected it to my engine.  When I turned on the key to the accessory position I get a buzzing sound.  I disconnected the NMEA 2000 cable from the engine and still get the buzzing sound everytime the key is turned to the accessory on position.  I even reconnected the NMEA 2000 connector to the original NMEA 2000 connector that went to the old harness and I still get the buzzing sound.  How do I get the buzzing sound to go away?  What have I done wrong?

The buzzing sound is comming from the fuel pump.  I started squeazing the priming bulb and then the sound stopped.  It is repeatable.  I don't know when this started when I installed the I-command gauge.

The HP fuel pump cycles everytime the key is turned on.

Should have always done it - guessing you just never noticed before due to ambient noise - I know I never did until a post on here mentioned it and I payed particular attention to listen for it. Mine will run for a few seconds and then stops even without priming with the ball

jimh   Love the comment.


I noticed he noise was different after I made changes to my EMM.  Has anything changed with your EMM? Firmwear update? Did you plug into it at all?

Low budget, love fishing. Cursed to own older boats that need more DIY attention than I really want to give them..
