So I got the motor back from Neu. No issues found but the bearings were replaced as a pre-caution. I reinstalled the motor and it is still doing the same thing. Bad shaking at near 50% throttle. I have a new prop that arrived today (Carbon APC) I am going to balance and install and see if the problem is still there. The only thing left would be the mount itself. It has a Hyde mount. The front is the rubber isolator disk arrangment that bolts to the motor and then the other half bolts to the fuse. The rear of the motor is supported by a ring. The rear ring fits snug. With the motor installed you can grab the prop and flex the motor about 1/8 inch in all the directions which seems normal but I am not sure.I am super frustrated!
