Decoding the OMC electric stringer sterndrive model numbers. 

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.

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.

OMC Designator Engine OEM Type Cu. In. Disp
DU OMC V-4 89.5
CU, GU, LU, SU, VU Chevy II I-4 153
HU Buick/Jeep V-6 225
JU, WU Chevy I-6 250
KU Chevy V-8 283
NU Ford (UK) I-4 98
TU-14,15, and 16 Buick V8 300
TU-17, 19 Chevy V8 307
TU-20, 21 Chevy V8 307
XU Chevy V8 307

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).
