Most of the more advanced pumps have buckets which shoot down and to the
sides(along with forwards), when you turn the nozzel, the side forces get
unbalanced and spin the boat. Often with larger jets the pumps are also
clutched and with multi units they have an option to independently control
the steering per pump.

All my experience has been with big block Berkeley and Dominator pumps.
Those keep a "neutral" by equally maintaining rear, and forward thrust.

A properly set up Berk or Dom will not move in "neutral" no matter what way
the nozzle is pointed.

Oh well...live and learn!
