A jet ski or personal watercraft is a craft that is designed to accommodate between one and four people and is powered by a water jet. These days you can find a personal watercraft that has the power to not only carry passengers, but you can also tow a person on water-skis or a wakeboard. Jet skis allow the rider to have a more exhilarating experience with the water than a standard watercraft.

The jet ski is propelled by a directional water jet drive. The jet drive pulls water through an inlet where it is accelerated by the motor and passed through a directional outlet. Depending on the type and size of the motor, the personal watercraft can achieve a great deal of thrust and acceleration. All of the moving parts are internal providing better safety and less propeller fouling.

Most jet skis are powered by either a 2 or 4 stroke engine. The 2 stroke models possess more power and torque for smaller engine size, but they are louder and require premixed fuel. Many modern 2 stroke engines now possess advanced fuel injection systems that better fuel efficiency and performance. Some 4 stroke engines have turbo chargers to improve power and performance.

When you are selecting in a personal water craft here are some important points to consider.

• Look for a craft that has the right power and load characteristics for the intended use. Don’t buy a solo jet ski and expect to carry passengers or town anyone.
• Make certain the jetski you select has the correct safety equipment including a lanyard style engine cutoff switch that will kill the engine if the rider falls off.
• Look for a model with an electric starter - Find a model with a trailer that has space for fuel and gear.
• Make certain the personal watercraft is approved by the boating authority on your area.
