Azipod units also aren't usually set up as "pullers".

Azipod is a trade name registered to the ABB corporation. Azipods are
podded azimuthing electric drives, and their design is based on placing
the propeller forward in undisturbed wake for highest efficiency.

You may be thinking of what are called "Z-drives" that are mounted on
tugboats and other small vessels. "Z-drives" are not Azipods but they
are azimuthing thrusters and may or may not incorporate a nozzle.
