[C320-list] Shaft Replacement

[David J Cardoza]

If it was driving smooth prior to being pulled it likely wasn't bent.
Think washing machine out of balance during high speed spin or tires out
of balance on a highway. 1/4" off = 1/2" wobble.

Thank you Jeff.  I would be interested in the place that you got the  
shaft.  The marina wants a lot of $$$ to do the replacement.  I think  
it is possible that the marina created the problem when they hauled  
the boat.  I have a 1/4" bend starting just after the cutless.  Don't  
you think I would have a lot of vibration in the boat if it was there  
earlier as a result from hitting something?
