The lack of a bushing does not seem to be a problem. I have had my 33 for over 10 years. The rudder has always worked well. The only problem is with a shoal draft boat. With the shoal draft the rudder is deeper than the keel. Any grounding will hit the rudder first and may bend the rudder post. This may force the rudder up to where it will rub on the hull. For my boat I had the rudder cut off 7" and 7" added to the trailing edge of the rudder. This makes for a square shaped rudder that works very well.
