Gentlemen. I have a 1982 Johnson 140 outboard Model # J140TLCNB Serial Number J56982**. I am setting the shift rod height and the guide I found lists two measurements. One for V4 and V6 60 degree of 21 5/16". And another for a V4 crossflow of 21 13/16" - 21 7/8". I'm pretty sure my motor is the crossflow V4, but I want to be sure. Thanks in advance
