Vibration when max turning at idle speed -- common?

When a skier is down I follow the proper procedure of slowing down to a near full stop, turning at idle speed and then going straight back to the skier at whatever speed is appropriate depending on the circumstances. However, when I crank the wheel all the way so that the rudder is in the maximum turning position I get a lot of vibration. I figured this was normal and just usually back off the wheel a little bit to reduce the vibration.

However, I was driving my buddy's early 80s Ski Nautique last night and tried the same procedure and it was totally smooth with the wheel/rudder all the way to max turning position in either direction.

Is this vibration I get common to Mastercrafts or just unique to my boat? What is the cause?

I don't feel this vibration anytime except in hard turns at idle speed. The prop looks like it has been worked on but there are no significant dings or deformities.

I think something might be wrong with your boat, although my boat is a different model I don't get any vibrations turning like you described, might want to check rudder and/or cable for excessive play.

I feel the vibration in the steering wheel. Where would I feel the vibration if it was from the prop?

I don't feel the vibration in the floor, so I guess that means it is not the prop. A friend of mine suggested that maybe a bearing in the steering system has a problem and is allowing the rudder to vibrate when cranked over to an extreme angle. If there is looseness in the rudder I assume I should be able to feel it by simply putting my hand on the rudder and trying to move it?
