Got an answer!
Emailed a Yanmar service/training center in NJ w/ pictures of the motor installation and the dipstick. Here is their response:
"It is our recommendation that you fill the crankcase oil to the "Full"
mark on the dipstick. This will give you correct lubrication under all
conditions and engine angles."
This makes sense to me so I'm going with it. The range of opinions I received was amazing, including one from Yanmar that made no sense at all. BTW, the dipsticks on Yanmar 2GM's differ. I have a dock mate who has the same motor and dipstick I do (2 1/2" between high and low marks). His motor is mounted with a mere 3 degree angle, compared to mine at 10 degrees. So, not all are 3/4" apart.
