How do you tell the correct orientation of the thrust washer on a 15hp, 2 stroke Mercury outboard motor?

Should not be that hard. Tape up the ends so you can hold it with out getting cut, (if its ragged or sharp from damage). should be one nut holding the impeller on. If its to tight to hold try air or electric Impact wrench. If its bad you can tap with a hammer to help in removing the old one. If it turned on the shaft you will need to rent a puller. Repost if you need more help.

SOURCE: Re-assembling lower unit of 40HP Mercury 4 stroke

I found a lower gear case assembly diagram at http://www.crowleymarine.com/mercury_parts/6995/240.cfm which helped me understand how the shift mechanism works. This clued me in to the fact that I was missing the cam follower rod which I then found I had inadvertently mopped up in a shop towel when cleaning up spilled gear oil. After that discovery, assembly and operation was quick and successful.
