230-51-5d Is a 51-54 5hp Based on the Gale 5D10 with 360 degree reverse.
Value is subjective depends intirely on condition and who wants it.
A comeplete non running motor of unknown condition $25 to $50
A good running comeplete motor 100 150.A factory new restored motor
200- 400.Again final price depends on who is buying it.
