Complete maps of the high-velocity (C-12)O emission of the B335 and L723 bipolar molecular outflows are presented, for which the angular resolution has been enhanced using maximum entropy. The B335 outflow appears to show a thin shell structure much like that of L1551 and lies nearly perpendicular to the line of sight, having an inclination out of the plane of the sky of only i = 9 + or - 1 deg. The outflow has a nearly constant opening angle from begining to end, where the outflow appears to have broken out of the cloud in both directions. Emission at the ends of the outflow shows signs of being reaccelerated. The mass of outflowing gas is about 1 percent of the molecular cloud and contains enough momentum and energy to disrupt the cloud core. The L723 outflow is very narrow and remains unresolved. Two nearly perpendicular axes of symmetry of the outflow suggest that the outflow axis has precessed. A curious sinuous ridge of redshifted emission traces the south edge of the blue lobe and may indicate a large velocity dispersion at the interface of the molecular outflow with the ambient cloud. 19 references.
