Vibration under power

Seems it is my turn... went out this afternoon and everything was ok for 2 sets then we felt a vibration starting at 1800 rpm untill on plane then you can just barely feel it. felt like damaged or fouled prop but no damage can be seen on shaft or propeller transfluid is full and not burned. I have read a lot of posts about engine and trans alingment. Can misalingment happen suddenly or am I looking at a trans problem? My buddy says it feels "like a bad u-joint".

Thanks for any help

Is it an Acme prop? They bend so easily you don't even need to feel when you touch the bottom to do damage. Noting like the old log grinding OJs.
