Is it normal to have the rudder slightly off center from the drive shaft? Mine rudder is off to the left of center of the drive shaft when looking at it from the rear of the boat. When I was at the MC dealer today, I looked at several new boats on the showroom floor and noticed that some of them were off center also. However, some appeared to be lined up with the shaft perfectly. :confused:

Yes, it is normal and designed in for most ski boats.

Totally normal. Slightly off center. If the rudder was directly behind the
the prop there would be some slop. This offset adds to the slight pressure that you feel on the wheel. This allow the boat to always track straight because you the driver are holding the wheel tight.

It also allows you to remove the prop shaft without having to remove the rudder assembly.

It is also slightly off to one side (or the other as in CC) due to rotational torque from the drivetrain. Otherwise the boat would have a serios built-in lean under power.
