Yamaho SHO revs way up upon starting.
Hello all, at about 35 hours on the motor every time i start it, it revs up to about 3000 rpms then settles down. Does this seem normal? It also seems like i can here something continuously running while the key is in the on position.. Thanks

It is not abnormal for some Yamaha's motor to rev up for a short period of time after it starts. My own truck (an F150) does it. Does not seem right but that is the way that it is.
I suspect that what you are hearing is humming from the electronic throttle valve when the key is in the on position.

3000 rpm seems high. Would be hard on a motor IMHO
