'01 Mobius with TBI injection. Had a problem with boat fouling plugs and running very rich (black, sooty smoke). Replaced both temp sensors and thermostat. The boat runs better but is still running a little rich and now it just takes longer to foul the plugs. DO THESE MOTORS HAVE OXYGEN SENSORS? If so, where is it located on the TBI engine? I assumed it would be in the manifold/ risers but can not find. ANY OTHER OPINIONS ON RUNNING RICH?
