Generally, you can't. If you can identify the model, you can determine the years in which it was manufactured, and sometimes narrow that down by variations in the model's specifications.
1966 20 hp.
The "J" in the model number signifies a Johnson motor. The 110 is the hp. The "T" says the motor has a trim. The "L" identifies a shaft length of 20". To answer your question, the "CU" signifies a date of 1987.
