There are a lot of reasons. If the drain plugs aren't in, that would do it. Also, the impeller shaft seals or carbon ring may be worn. One way to tell is to get the jet ski dry, place it in the water, and then run it with the seat off. You should be able to tell where the water is coming from.

What will cause a jet ski to take in water?
damage to the hull or drain plug(s) not in place or missing. Another cause for a jetski taking on water can be loose rubber hoses inside the hull. If a rubber hose that is connected to the exhaust is loose the hull can quickly fill up with water. If you notice your hull is filling up with water get to the shore and check all the hoses to make sure they are installed properly. This is usually the number one reason why a ski without hull damage takes on water. Especially if the engine has recently been installed after a rebuild. Even professional shops will occasionally leave hoses loose. I have helped numerous folks at the lake because they find their ski full of water before they even leave the boat ramp, serous damage can happen to the motor if the water is sucked into the reed cages and not taken care of properly.
Where is the water drain in a 1989 kawasaki jet ski?
In a 1989 Kawasaki Jet Ski, the water drain is typically located at the rear of the watercraft, near the bottom of the hull. It may also be near the engine compartment where any excess water can exit the ski. It's important to check the owner's manual for specific locations and maintenance tips related to the drain. Always ensure the drain is clear to prevent water accumulation.
Can you crank a jet ski out of the water?
Yes. You can crank and start a jet ski out of the water. However, without water, there will be no cooling for the engine, exhaust, and driveline. So generally it is not recommended to let the engine run more than a few seconds. Many people crank a jet ski out of the water to prime the fuel system prior to placing the jet ski in the water.

No they don't. The force of the water against the front of the jet ski will stop it when you slow down. :)

How does a jet ski powered jet pack work and what are its main features?
A jet ski-powered jet pack works by using water propulsion from a jet ski to lift the rider into the air. The main features of a jet ski-powered jet pack include a harness for the rider, a hose connecting the jet pack to the jet ski, and controls for steering and height adjustment.
Why does a jet ski pump water out the exhuast?
A jet ski pumps water out of the exhaust as part of its propulsion system. It uses a jet propulsion mechanism that draws water from the body of water, pressurizes it, and then expels it through the exhaust. This process not only creates thrust to propel the jet ski forward but also cools the engine by circulating water through it. The expelled water creates a visible spray, which is characteristic of jet ski operation.
