These are the pros. The cons are basically just the opposite...

Water jet:

higher speed without cavitation
smaller machinery (but it's basically inboard)
smaller draught requirement
increased manoeuvreability with a steerable nozzle
(potentially) quieter
doesn't chew up divers/fish

Propeller(s):

doesn't take up as much internal space
cheaper
more efficient at low speed
lighter
easier to clear if clogged
