Not long, but it depends on the motor. Water is used in many boat motors to cool the engine and carry away exhaust. Motors that do not have radiators or heat exchangers will rapidly overheat if run without a supply of cooler water.
The definition of motorboat is any kind of boat with a motor that runs it. It is usually any type of boat that is available as long as it has a motor. For example, a car is not a boat so it is not a motorboat.

Depends on how fast the boat is traveling. On a boat traveling at 30 mph it will take 30 minutes.
It depends where you're sailing from!
A boat floats because it is less dense than the water it displaces. The upward force acting on the boat from the water is called buoyancy, which counteracts the force of gravity pulling the boat downward. As long as the weight of the boat is less than the weight of the water it displaces, the boat will float on the surface of the water.
In theory yes you can. As long as the engine will fit in the boat, is waterproofed, and can be rigged to move the boats propeller.
The answer depends on the average speed of the boat and how long you can maintain that speed without stopping for refuelling, rest and so on.
Yes, a paper boat can float on water as long as it is well-made and the paper is not too thin. The boat's ability to float depends on its design and the displacement of water.
This question depends on the type of boat you have. Normally as long as your boat can do around 25+ mph you should be able to pull a skier out of the water. So if you have a 18ft boat with a 115hp depending on the weight of the boat you will be able to tow a skier out of the water.
Any age, as long as you have a license. Once you are 12 you can drive a boat with of any horse power.
In theory yes you can. As long as the engine will fit in the boat, is waterproofed, and can be rigged to move the boats propeller.
Water about a minute and oil not very long at all!! hope this helps... Some electric motors are designed to run for years without either. If you mean, instead, "a water-cooled gasoline engine", you might expect it to run for a few minutes but it will be damaged.
