Response to Hello Dan.  The Century 1.5 HP Square Flange 56Y Full Rate EE Motor - B2842  or  Century 1.5 HP Square Flange 56Y Full Rate Motor - B2858 are compatible Single-Speed replacement motors for the model 0-193990-07.   The Energy Efficient B2842 is slightly more expensive than the B2858.  The reduced amperage draw of the B2842 pays back that investment in approx. 3 months time based on an 8-hour/day operating cycle.
