Yamaha Mercury 8A P165 service manual

Hi all!
I saw some posts earlier from people trying to fix up an old 8A P165 from Yamaha/Mercury. I'm in the same boat with my dad, badumtss 

I'm searching high and low but no luck locating its service manual. I have the owner's manual but it'd quite limited.

Anyone might have it on an external drive somewhere in the attic? It would be really useful for us to go ahead with this little project.
