I have two 70hp motors.

* One is model# 70473-M and the other is 70773S.
* How do I switch lower units?

I tried last year on the earmuffs but it didnt work.
I think I was getting reverse in forward and neutral in reverse.
Cant quite remember, but it definately wasnt right.
Is this just a matter of having two shift rods that are different lengths and swapping?
Or is more that I need to do?
