Color-selecting IRAS sources provides a convenient means of pinpointing likely new water masers, an approach first tested by Engels et al. (1984). The initial results are reported here of a more extensive survey, during which 60 masers, 49 of them detections, were found. Most are associated with 1612-MHz masers, but seven are sources without other known masers. The results rule out the binary hypothesis as a plausible general explanation for the existence of the many sources having far-infrared colors typical of OH/infrared stars, which show no sign of any 1612-MHz emission. The data support the idea that sources evolve in both their colors and their rate of mass loss.
