Question

how does motor boat work ?

Answer 1

A boat motor works like a car engine. It contains a series of piston heads in cylinders that move up and down. These pistons are connected to a crank shaft, which is turned as the pistons move up and down. The force that drives the pistons and causes them to move up and down is a small explosion of gasoline or diesel fuel. The more fuel pumped into the cylinders, the faster the pistons move and the faster the motor crank shaft spins.

Answer 2

In a motor boat, instead of driving a gear box the motor power a propeller. To steer a boat with an outdoor motor, you simply tilt the whole motor casing so the whole propeller pushes the water away from it an angle.
