Decoding the OMC electric stringer sterndrive model numbers.

Also see: Sterndrive, Ltd.'s OMC Identification Guide for 1968 - 1977

OMC offered many engine combinations with the electric stringer sterndrive over the 15-year production life from 1962 to 1977. An alphanumeric model number schema was used from 1962 through 1972. Beginning in 1969 a more detailed schema was employed to detail the various mounting and steering options. An all-numeric schema was implemented in 1973. View 1973 - 1977 Electric Stringer model numbers here.

OMC assigned each engine family a unique two-letter alpha designator:
A third letter (E) is used to designate the "extended"  (high profile )15-inch lower unit leg, which was 4.5 inches longer than the "short" (low profile) leg version.

All OMC/Evinrude/Johnson boats utilized the "extended" drives.

The two-digit numeric indicates the sequential model year, beginning in the first year of production, 1962 with "10,"  1963 with 11, 1964 with 12, and so on up to "20" in 1972.

From 1969 to the 1972 additional letters indicate the mounting system and steering system, following the two-letter engine type designator.
The third letter position is either "F" = Floor Mount, or "T" = Transom Mount.  The fourth letter position indicates the type of steering system with "M" = Mechanical, "R" = Rope/cable/pulley, and "P" = Push-Pull (TruCourse closed-cable).
