[C320-list] Fwd: Re: Fwd: shaft alignment

[Jerry Brown]

Hi

On our MkII there was insufficient adjustment available to allow the shaft 
to be aligned with the boat as delivered.  The prop shaft was hitting the 
hull.  After a lot of work by the dealer and Catalina the issue was 
resolved.  They never shared with me the full solution but I do have 
modified engine mounting plates and a different coupling.  There was also 
work done on the hull where the shaft exits the hull.  If you are not able 
to stop the noise following the approach suggested on list you may want to 
contact your dealer and or Catalina.

If this is the situation occurs which I hope it does not give me a ping off 
list and I will give you more background

Regards
