2012 Yamaha 20hp exploded diagram

I'm trying to sort out a carb issue with a Yamaha 20hp 4st.

Unfortunately the owner has been in to the carb before me and I think there might be something missing, could do with an exploded diagram.

Where would I get one?

How about this? - might not be the right model (there were many 20HP's).

Unfortunately the deposits are salt.

Apparently the engine was on a boat that had turned turtle in a storm.

Looked through the oil filler and cam lobes are rusty and 250ml of water came out of the sump BEFORE the oil appeared.

The end is near!
