Before I start pulling fuses... It is a low volume buzzing sound, like a small electric pump, that continues as long as the key is in the ignition in ON position. Normal?

I've heard it is the electronic throttle valve, wonder if others have had the same going, or do I need to investigate?

Mine (F300 UCA) makes the same high pitch humming sound with key on. Electronic throttle valve responding - does the same with the motor running but you just can't hear it over the motor.

My F250XCA 4.2 (same motor) does the same thing. Electric throttle valve from everything I have researched

Hi Swatski, 'Dittos' to all the other responses... Our F300 UCA does the same....

Thank you, that is reassuring. Not well documented in any Yamaha manual I know of.
I my boat the ignition key controls only the Yamaha command link, I still have all other systems working with the key OFF.
