Very much like an engine in any other vehicle. The most obvious difference would probably be the cooling system.
That depends on the type of boat and whether you you have an inboard or outboard, or a gas or diesel engine. look at http://newboatbuilders.com/pages/carbonmonoxide.html The worst situation is a boat with enclosed living spaces, an inboard gas engine and an exhaust system leak. But boats with as powered generators have had significant problems too. On a cabin motorboat you can get a stationwagon affect from the low pressure area immediately behind the boat causing exhaust to be trapped behind the boat. We would need a more specific question. What type of boat, how big, gas engines? does it have a generator, air conditioning?
Running the exhaust blower will expel fuel or exhaust vapors trapped in the engine compartment. This is a precautionary step. A visual inspection the engine compartment is also a good habit to get into if you have not started the boat for some time. Things to look (and smell) for in the engine compartment that might tell you something is wrong with your boat before you start it include: fuel or exhaust, water, and broken or loose motor parts.

what does a no power boat ahead sign look like
The boat is built on a set made to look like a basement. The boat is wheeled out, like any other prop, to make room for a new boat project.

It was an old fashioned boat with a sail and people hoisting stuff.
