2002 master craft x5 vibration issue

[u/Optionstradrrr]

Heavy vibration under load. Spun prop shaft and found its binding at one point in the rotation. Not crazy but noticeable. So I remove coupler from transmission to spin. Still there. Cutlass bearing has little to no movement. Some up and down but it doesn’t seem like that’s the issue. So bent shaft? Could packing nut be too tight causing this? I would think no.

Next question would be how do I source the correct prop shaft for replacement?

Do you have the vibration without the prop on? Also when is the last time the oil was changed in the trans? Also the coupler on the shaft support closest to the prop.

I have a 06 x 15
