The propeller thrust is not going to go around a corner, through two sets of bevel gears in an outdrive. It is also not going to go through a V-drive.
My Ski Nautique has a 1.23 to 1 reduction transmission, the thrust does not make it past the driven gear in that transmission.
I would think that most "direct drive transmissions", even ones that have the propeller shaft in line with the crankshaft have a thrust bearing somewhere in them.

It is possible that some design may apply propeller thrust directly to the thrust bearing on the crankshaft, but I cannot think the thrust bearing on the crankshaft would last very long in that application.

Hey DanielC, What year Nautique do you have? Been working at the company that built your drivetrain for 15 years.

Troutman,
I have a 1997 Ski Nautique, with 2443.3 hours. It has the Ford GT-40 engine, and is still running great. The hull was built in October of 1996.
So, you work for PCM?

Yes, that GT-40 is an awesome engine w/ plenty of torque. I worked in the warranty for my first 9 years, and now i build subassemblies such as motor mounts, fuel control cells, potentiometers for drive by throttle and catalytic converters for our exhaust systems.
