Brand new 6015 vibrating very bad

[tangstank]

I got a brand new 6105 & plugged it in yesterday. It seems to be vibrating a LOT. I had it on the mount & the vibration is causing loud noise, & when I held it in my hand I noticed it was unusual vibration than my other 6105 (few months old)

What could be the issue here?

My best guess would be either the shaft is bent or a blue silicon bushing is missing at the end of the shaft. Keep in mind humans assemble everything so occasionally a piece is left out. I would take the propeller out and seperate the shaft and roll it flat on a counter to look for any warp or bow, the newer pumps use a pure titanium shaft, older pumps were 316TI, the pure titanium bends easier so is more prone to bowing. Also check that both silicon bushings are present at either end of the shaft, I can send whichever part is needed. Just PM me what you need and your address.
