The laws of momentum. The boat is on a frictionless surface (water). The engine turns the propeller, which forces water backwards at speed. Since there is nothing to stop the boat moving - it moves forwards.

What relation do you find between the weight of the floating body and the waight of water that is displaced?
They are equal.When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down.Note - relation between volume(v) mass(m) and density(d) : d = m/v
A motor with an efficiency of 75 percent must supply 240 J of useful work. What amount of work must be supplied to the motor?
At least 320 J
How many knots is 15hp?
Doesn't work like that. 15 hp is the power of the motor, but the speed you get from 15 hp would depend on how hard it is to push the boat through the water. 15 hp on a canoe would be scary fast while 15 hp on a barge won't do a thing.

how does a brushless motor work?
A brushless motor has many jobs to do. It works in many different ways. In most or all cases, it helps run the boat. The motor is what keeps the boat going. http://en.wikipedia.org/wiki/Brushless_DC_electric_motor
