Evinrude 90HP question

[azsportpilot]

Hello all, I'm new here

I'm looking at an older boat with a 1991 Evinrude 90hp on it

NADA lists 2 models:

E90TLEI..... $945.00
and
E90TLAI......$925.00

whats the difference, NADA books the E model a bit higher in value

any help would be greatly appreciated
thanks

ok, so i found the model decoder in the sticky above

still can't figure out the "A" model

E= Evinrude
90 = 90hp
EI = 1991
AI - ?

E-90-JL-EI....J = Jet Drive,………………………………... L = 20” Long
E-90-ML-EI...M = Manual Tilt - Electric Start,….… L = 20” Long
E-90-SL-EI....S = Sail - Special Styling,…………….. L = 20” Long
E-90-TL-AI....T = Trim and Tilt - Electric Start,…. L = 20” Long……… not sure what the “A” means, EI is 1991… AI is? (Still built in 1991 apparently)
E-90-TL-EI....T = Trim and Tilt - Electric Start,…..L = 20” Long
E-90-TX-EI...T = Trim and Tilt , ………….....………….X = 25” X-long

EI - 1991

so what the heck is an E90TLAI?
