73 starcraft old merc to new merc

[RiverNoob]

Howdy everybody.
Been a while. Was wondering how hard it would be to update this boat to a newer merc like an alpha gen 2.
What's the minimum needs to be done for that?
Can you keep old engine and change out mate, gimble,, get adapter?
Does transom have to be redone?
Etc etc.
Thanks Fer lookin

Per Alpha to Gen 2 would to change out transom assembly, gimbal rings are different


Probably need to change out engine coupler, @Bondo and @Bt Doctur can help

Ayuh,...... You need to replace everything from the flywheel cover, 'n aft,....
The keyhole in the transom might need some tuning, but not to much,.....
