Can I swap factory tilt/trim from Mercury version 85hp to US Marine version 85?

[The Force power]

in 89 they changed water pump styles.
Not positive but they might swap(not parts,whole pumps)
They introduced the Hell Drive and needed a stub shaft to connect to the L drive.
I believe in 90 when they started on the 90/120/150 they standardized the gear ratio. They all had the same ratio at one point. Markings on the case should tell what's in there.

After seeing the pics: Both motors are US. Marine
The drive with the short shaft is from the 90's
not positive what year but doing some research can figure it out???
