Yanmar 2gm20f 16 hp Dip stick location

An access port might help here...

My boat has the 2GM20F as well. I found it to be fairly challenging to accurately pull, read and replace the dipstick when facing the engine head on.

Apparently, the PO had the same problem and I figured out quickly what the add on access port (screw on type) in the head was to be used for...it allowed easy access to the dipstick.

You may try this option in the future.
