It seems the amount of money you get can depend on where you are on the trade route, and/or changes randomly. For one example, as Britian at war with pretty much the entire Med. Basin, I had a fleet of ships blockading a combined French/Spanish/Maratha/Russian/Italian trade route. At one point, I moved the ships from just inside the Med to just outside, and my income jumped up by about 6000.
