Also how is this cooled? From my knowledge it should be liquid like all other boat engines, but I can't find any intakes or places where the water would exit. It does not have a fan on the fly wheel either.

Throttle is more controlled by ignition timing than the carb throttle opening. I'm not exactly sure, but shutdown might be just by retarding the throttle till it can't run. The throttling arm moves the whole ignition plate, and also opens/closes the carb butterfly as it moves. I figure it has a single carb for both cylinders? As to shop manuals, you'll need to do some google digging. Here is some info:
that explains the oversized, connected to every thing throttle. There is just one carb for both cylinders.

I had an old Mercury with no apparent kill switch. The choke was the kill system of choice.
Be sure it pumps water through the cooling system when you start it up. There's usually a telltale hole that pees water below the power head and above the water line so you can see it working. A common problem is a bad water pump impeller or clogged passages.
