Jet ski better known by the name personal water craft i.e PWC are like the motor cycles of the sea. u can basically cruise down the sea and feel the ocean breeze.
They are generally basically designed just like a normal vehicle with a normal piston engine. its starting system also similar i.e it includes a starter motor and solenoid but the funny thing is it has no transmission but instead the engine is coupled directly to the impeller by the drive shaft as shown below.
How a Jet ski works
The engine rests on the body of water that acts like a heat ex-changer hence cooling it, The impeller draws water inwards behind the personal water craft towards the steering nozzle faster than it gets in propelling the jet ski forward. the steering nozzle is activated either right or left by moving the steering handles to either direction this pushes water sideways hence steering the jet ski. in case you want to move reverse with no transmission the water from the steering nozzle is channeled to move downward towards the front hence reversing the jet ski. Just like a motor cycle a jet ski’s speed can be increased by a throttle located in the right handle.
A jet ski is not designed for deep waters or long haul trips due to its lack of navigation and enough safety equipment but its still a magnificent piece of naval engineering as shown in my types of modern ship article. they are also known for their speed hence used by many life guard, police and mostly the navy. They are designed safe, buoyant & streamlined enough to cruise on sea although high speeds without capsizing or tipping over when steering.
They are mainly used by tourists on the beach on vacation for recreational purposes or set out for sports and racing activities. They have a sitting capacity of two to three people.
