 Dear Group,
I just hauled my boat for bottom paint and it looks like I have a shaft
alignment issue.
Here are links to pics

Facts
1.	The boat always had a bit of vibration between about 1500 and
2200 rpm
2.	I did wrap a line around the prop last summer but did not notice
any problems - vibration etc.
3.	The mechanic did to alignment etc. 12 months ago.
4.	Boat was surveyed 2 years ago before purchase
5.	The strut looks like it is offset a bit to port (not 90
degrees). Not aligned with rudder? 
6.	No visible wear on cutlass
7.	Evidence of shaft rubbing on bottom of log tube as it exits the
boat. See pictures shaft is buffed inside the log tube
8.	Hull 972 2004 Catalina 320

Questions:
1.	Looks like I need to replace strut?
2.	What process should I follow to troubleshoot?
3.	If strut is bent what other parts do your recommend to replace
while I'm at it
