[PSUBS-MAILIST] U joint prop

[Marc de Piolenc via Personal_Submersibles]

One U-joint causes a 1/rev vibration which can be quite severe. To get 
smooth action, you need a pair of U-joints, and the input and output 
shafts need to be parallel.

That, or you need to substitute a constant-velocity joint for the U-joint.
