How are jet skis powered?

What fuel do jet skis use?

Jet skis primarily use regular unleaded gasoline and premium gasoline. This is largely dependent on the specific model and manufacturer of the jet ski. If you are hoping to save money on gasoline, look for a jet ski that will take regular unleaded fuel.

How does a jet ski propulsion system work?

A jet ski generates forward thrust with a unique “corkscrew” style impeller. It draws a large volume of water into a propulsion channel, and then forces the water out through a size restricted cone shaped jet nozzle.

How far can a jet ski go on a full tank of gas?

In general, a jet ski can go somewhere from 75-150 miles on a tank of gas. Again, these numbers could vary widely depending on several factors like the jet ski’s performance, curb weight, fuel capacity, or the weather conditions.

How much is jet ski fuel?

The average cost is going to be around $50 per tank of gas. Again, you will have to experiment with your specific jet ski and see just how much it will be. Gas prices are changing all the time, so keep that in mind when calculating price too.

Are jet skis easy to work on?

Yamaha’s waverunners are not only dependable, but easy to work on. Many people are okay with occasional maintenance, (and they should be) but some engines can be very difficult to work on even for experienced mechanics.

Do jet skis have jet engines?

Your jet ski has a jet propulsion engine, which has an impeller that uses rotating fan blades to suck water into the engine and then forcefully eject it. These two motions—sucking in water and then ejecting it back out—are what propel the jet ski forward. Jet skis have throttles, similar to those on motorcycles.

Why do jet skis shoot water out the back?

The motor works hard to suck water into the vent at the bottom of the machine, and propel it from the back. Some of that water is used to cool down the motor so the watercraft does not overheat. Once the water has completed its cooling duties, it is expelled out the back of the vehicle in a neat water plume.
