Looking at my friends 81 Centurion yesterday and noticed that the Shaft and Prop is offset about 15 degrees from the rudder to the passanger side of the boat when looking at it from the rear. My SS is directly aligned with the rudder. Does anyone know if this is normal for a older Centurion?

The nothing looks bent and the prop and shaft turns with ease. The boat is smooth in the water with little or no vibration.

Any old timers out there ?

Probably offset to facilitate shaft removal as well as an attempt to offset prop walk when in reverse?

My PS 190's shaft was not inline with the rudder either.... I think..... It may have been our old Hydrodyne, but I am pretty sure it was my MC

Yup,
I had an 81 Nautique that had the same type of offset.

I know in single engine airplanes, the engine and/or rudder is mounted slighly off to compensate for the tourque of the engine pulling to the left at normal speeds. At low speeds and high power like during take off you have to compensate with more right rudder. Seems like it could be the same principle here.

My 85 Powerslot is offset a little bit - I can't quite get the shaft out without removing the rudder

15 degrees? That's about 6". Is it really offset that much?
