This can hydrolock the engine leaving you stranded on the water possibly doing permanent damage. When you ride a jet ski, most of the time you get water in the hull.
This just happens as you are riding a craft on the water with air intakes to the engine bay. If you were to flip the jet ski, water rushes in the hull while it is waiting to be turned back over. There is a right way and a wrong way to flip the jet ski back over rightsize. If you flip it the right way, you will be fine, the wrong way, and you will send water rushing into your intake system or carburetors which can cause your engine to hydrolock and leave you stranded. Typically jet skis have a picture on the back of the ski illustrating the correct way to flip your craft.
If not, check your owners manual. When the engine runs or is cranked and the intake got water in it, it creates suction that can pull water into the engine.
Normally the engine will stop before damage occurs, but forcing the starter on the engine to cycle could cause irreparable damage. Once water is in the engine in any capacity you need to get it out of there as quickly as possible.
Leaving water in the engine for any length of time can lead to severe and costly damage, including engine replacement. Leaving water in there for even the span of a few hours can lead to the piston rings seizing to the cylinder wall, the crank and bearings to rust, and for the engine to seize beyond repair. Even if there appears to be other damage, for instance, if your jet ski was flipped during a collision or accident, it is imperitive that you get it correctly and safely flipped right side up, and get to shore to begin getting the water out of the engine.
This is the more common outcome of doing an uncontrolled or improper flip of the jet ski while it is running. The intake becomes submerged and it pulls water into the engine, generally stopping it very quickly by simply preventing ignition. This condition can be diagnosed by trying to start the jet ski once it has been properly flipped over in the water and being unable to start.
If suspected, it can be confirmed by pulling a spark plug and checking for moisture. Even as this is the least severe of the outcomes of flipping your jet ski, this is still a serious situation that requires you to take immediate action or risk irreparable damage to the engine of your jet ski. A hydraulic lock or hydrolock is a dangerous and often costly condition that can happen if the engine is forced to cycle while water is in the intake.
As above, its this propelled water smashing with the surrounding water around you that moves you forward. The water being pushed out the back would just fall down to Earth, giving you no forward motion whatsoever. Some people will choose to install motorcycle engines in a jet ski, as they have similar power ratings and, in some cases, fit right in. Modifying jet skis is only something that should be done with a licensed service professional, unless you have extensive experience. In most cases, you can top out at speeds of about 40 MPH, but there are many which are much faster.
Higher speeds come from having higher-powered motors, or those with a higher horsepower rating. But, as with everything that is exciting, there is obviously risk involved. At Sea the City, we take the most inexperienced riders and get them up in running in minutes.

Further, follow-up actions include returning the jet ski to its original upright position and switching off the engine.
If you are not familiar with the particular brand or model of the jet ski, a sticker on the bottom should provide detailed instructions on the correct way to do so. Reboarding the jet ski also requires some information and perhaps a certain level of skill in order to remain on board and not flip the watercraft again. Depending on the amount of water that the PWC has taken on, it is advisable to leave the engine switched off, start the bilge pump and have the jet ski towed back to shore.
If the watercraft was not flooded, and you are able to successfully flip it and re-board, you can continue the fun, remaining mindful of safety precautions and safe operation. A flipped jet ski is most likely an unmanned vessel, which could cause a collision and potentially life-threatening injuries if there is an accident.
These vessels are usually traveling at high speeds and being operated in a fun environment where people normally throw caution to the wind.
These are prime circumstances for disaster to strike. Observing various safety measures by operating responsibly, wearing appropriate clothing, and recommended accessories such as helmets, personal floatation devices , and other protective equipment reduce the risk of bodily injury in the event of an accident.
The engine shut-off cord, also known as a lanyard, should be worn at all times so that if the operator becomes separated from the PWC, he can switch off the engine to prevent accidents. It is imperative that one respects nature and the unpredictability of the open sea, and the fact that personal watercraft are powerful machines which must be operated with care.
