760 superjet terrible vibration

I have a 1991 Superjet that has a 61x Waveraider 701 in it. When you barely pull the throttle, it shakes the whole ski to when your going on plane, after that its fine, runs smooth unless you drop it down where you get off of plane?? Any help???
 
So that looks like the most common problem? Though mine only shakes when I barely give it gas to idle out of a no wake zone and that's when the shaking starts and ends when I am standing up, going..
