By 'spitting' I am referring to the steady stream of water that is
ejected at the back of the motor when it is running. The motor is a
90hp Mercury 4-stroke. For this type of motor, when it is out of the
water, should water also be ejected somewhere else, such as the
through hub exhaust as you mentionned ?

How safe is it to run an outboard out of the water but connected to a
garden hose with "muffs"?

Perfectly safe.

Is the water spitting a safe indicator of proper cooling?

Define "spitting".

Is there a steady stream from the tell-tale, and some water coming out
the through-hub exhaust (if so equipped)? If so, you're probably fine.

If you are getting a steady stream through the tell tale then water must be
coming out of the hub.
