My retrofitted 4.3 TBI motor in a boat runs only open loop.  It still uses half the gas of the carb setup on the same motor. Look at the link below for details if you are interested.

+AD4-I worked with a former boat mechanic a few years ago who told me that mercuiser was using the vortec 350 in the boats for more power and fuel economy. They didn't use an o2 sensor because with the water cooling of the boat exh manifolds it can't stay hot enough. So the motor is just run in open loop. You may want to check that out.
