Author Topic: Identifying Older Johnson Outboard Motors Model Numbers JBCornwell posted 11:16 AM ET (US) Up to about 1970, Johnson Model numbers were two or three letters and a two digit number. Prior to 1960 the RD seriers were based on a 40.5 cu-in. After 1960 the RD series were based on a 43.9 cu-in. The RX series were based on a 35.7cu-in. Block, and so forth.

Though the number usually identifies the year of production of that model, it is not a calendar year code. After 1970 model numbers include the HP, as in J33ELUTa. J=Johnson 33=HP E=electric start L=long (20') shaft UT=year code (see below) a=production run [After 1980] the year code uses the letters of the word, 'INTRODUCES' to represent the digits 1-0.
