What Determines The Direction A Pwc Will Travel?

PWC are propelled by a jet drive where water is drawn into a pump and then forced out under pressure through a steering nozzle at the back of the unit. This «jet» of pressurized water is directed by the steering control—when the steering control is turned, the steering nozzle turns in the same direction.

What is needed for steering control on a PWC?

Most PWCs have a lanyard connected to the start/stop switch. If your PWC is equipped with such a switch, it will not start unless the lanyard is attached to it. Never start your engine without attaching the lanyard to your wrist or PFD. If you fall off, the engine automatically stops running so your craft will not travel a great distance and you can easily swim to it. PWC operators need to keep in mind that a jet drive requires moving water through the drive nozzle for maneuverability. In other words you must have power applied in order to maintain steering control. If you release the throttle to idle or if the engine shuts off during operation you will lose all steering control. In either situation, the PWC will continue in the direction it was headed before the throttle was released or the engine was shut-off.

It will prevent the PWC from running unattended in areas populated by swimmers or other watercraft. Operation of the steering control will have no effect. If you are approaching a dock, shore, or other vessel at a speed greater than you can control and you release the throttle to idle or shut off the engine, you will have no maneuvering capability and the PWC will continue its forward movement.

Newer PWCs have a reverse mechanism that you can use to slow the forward motion of the vessel. These PWCs are equipped with cowlings that allow them to operate in reverse. The reverse cowling is a specially designed diverter that can be lowered over the jet nozzle.

The water jet produced by the jet nozzle hits the reverse cowling and is directed back toward the front of the PWC, thus producing a force that propels the PWC backward. Although this feature is convenient for low speed operations in close quarters, it can be quite dangerous if used in situations for which it was not designed.

Operating in reverse can greatly reduce the ability to steer. Using the reverse feature at other than idle speed can throw the operator forward, and perhaps off, the PWC. In addition, using reverse at high speed can raise the stern of the PWC, pushing the bow down and under water.

What is the best way to roll PWC?

Most manufacturers have placed a decal at the rear or bottom of the craft that indicates the direction to roll your PWC to return it to an upright position. If no decal exists, check your owner’s manual or ask the dealer. With this information, you should be able to roll the PWC over and reboard with little trouble.

What is the best way to roll the PWC to turn it upright?

What is the best way to roll the PWC to turn it upright? Roll the PWC according to the decal on the craft. Which of these is the most common cause of fatal boating accidents in Florida?.

Which action is safe for a PWC?

Keep hands, feet, loose clothing, and hair away from the pump intake area. Before cleaning debris from the pump intake, be sure to shut off the engine. The jet of water exiting the steering nozzle at the rear of the PWC can cause severe internal injuries.

What determines the direction a PWC will travel quizlet?

PWC are propelled by a jet drive where water is drawn into a pump and then forced out under pressure through a steering nozzle at the back of the unit. This «jet» of pressurized water is directed by the steering control—when the steering control is turned, the steering nozzle turns in the same direction.

What is the most important thing to remember about steering a PWC quizlet?

The most important thing to remember about steering most PWCs (and other jet-drive vessels) is that you always must have power in order to maintain control. If you allow the engine on a PWC or other jet-propelled vessel to return to idle or shut off during operation, you may lose all steering control.

Which way do you turn a jet ski back over?

Riding your jet ski is a great way to enjoy a summer day. While most are easy to handle, accidents happen, including flipping it over. When this happens it’s important to know what steps to take so you don’t permanently damage your jet ski or its engine. Here’s what to do if you flip your jet ski. What Determines The Direction A Pwc Will TravelThere’s a sticker on the back of most jet skis that shows you how to right it. Read the directions and follow them. If you don’t, you could force water in the crank case and the jet ski won’t restart. When water gets in the crank case it can damage the engine. If you’ve flipped your jet ski and the engine is still running, turn the engine off first to minimize the chances of water getting sucked in through the air intake.

For most jet ski models you’ll want to flip them back over in a counter-clockwise direction or the direction that allows the exhaust to hit the water last. If water is in the crank case, get your jet ski back to shore.

Next, remove the plugs. With the plugs out and wires grounded, crank the engine. Grounding the wires avoids igniting fumes. In most cases jet skis have a ground lug for the plug wires. You’ll want to clean and dry the plugs. Then put a small amount of fuel in the cylinder holes before reinserting the plugs.

  1. Now you’re ready to crank it
  2. If your jet ski starts and stalls, clean and dry the plugs again
  3. Sometimes starting fluid cleans the plugs quicker
  4. You can keep applying starting fluid to the plugs and starting the engine until it starts

Once the engine starts, let it run for 30 seconds and then put it on the water. Let it run on the water for a while, 5 minutes or so and everything should be okay. Letting your jet ski sit with water in the crank case for any amount of time will ruin its engine.

The longer it sits with water in the crank case the more damage that will occur. It won’t take long for the engine to seize up, for the crank and crank bearings to rust and for the rings to seize to the cylinder walls.

When Steven Haig of Imperial, Missouri sunk his Yamaha Wave Runner he had to have it towed back to shore. Unfortunately, when it flipped and sunk it hit a submerged rock. It took two hours to bring it back up to the surface. The hull was so damaged the crushed fiberglass couldn’t support the jet ski’s weight on the trailer.

Haig knew the importance of removing all the water from the engine. He refused to let it sit over night with water in the engine. The day it sank he worked an hour and a half to get the engine running. A week after he got the engine running he repaired the hull.

Sometime later he rebuilt the carburetor from the water in the engine and didn’t experience any additional problems after that. Two years later, his Yamaha jet ski is back in use. It still runs great..

How should a PWC be rolled after a fall?

Reboarding a PWC — Should you fall off your PWC don’t abandon it. If it has not righted itself, turn it over. Most PWCs carry a label on the hull that indicates the direction that the PWC should be rolled. Be sure to right the PWC in the direction that the label indicates. If yours does not have a label, check your owner’s manual.

  • Approach the PWC from the stern and pull yourself up onto your knees on the boarding platform.
  • From there continue to pull yourself back up on the seat.
  • Be sure to attach the kill switch lanyard to the kill switch and to your body or PFD.
  • Start up and get back underway.

You should practice reboarding prior to operating the PWC to make sure you are able to do it alone. Remember, a PWC is less stable when idle in the water.

Do jet skis tip over easy?

How to Avoid Capsizing a Jet Ski —

  • Choose the Correct Jet Ski: First things first, begin by choosing the jet ski that fits you best. Should you decide to go with a stand up jet ski, keep in mind you will most likely end up swimming in the water several times. Older, vintage jet skis, as well as the new two seater Rec-Lite models, aren’t the best option if you enjoy riding regularly with passengers, or prefer to bring along a lot of gear.
  • Speed is Too Low:  Believe it or not, when a jet ski capsizes with multiple passengers, more often than not, the speed was most likely zero. A jet ski is more stable when they’re in motion! On the other hand, you must maintain a continuous speed during your turns. Without throttle, a jet ski can become unstable, or even unsteerable.
  • High Speed and Tricks: As obvious as it may seem, another easy way to flip a jet ski, is to take a turn too fast. You are guaranteed to flip a jet ski if you’re speeding forward before suddenly taking a sharp, out-of-control turn. Tricks and stunts, such as wave jumping, can also end with a capsized jet ski – even resulting in serious injuries. Be sure to know your limits when choosing to ride aggressively!
  • Too Much Weight: Always educate yourself on your jet ski’s weight limit, as an incorrect weight distribution can lead to issues of instability. A sudden wave can easily turn your jet ski over, if there is too much weight on the ski.
  • Passengers: Riding with passengers is always more difficult, which means more risks. Something as simple as a passenger who doesn’t shift their weight correctly in a turn, is enough to cause your jet ski to capsize. This is why it’s crucial to learn how to ride with passengers on a jet ski.
  • Drain Plugs: If you forget the drain plugs, this could be enough to make your jet ski capsize if a lot of water leaks into the hull. More significantly, the jet ski may start to sink.
  • Sucking Up a Rope: It’s important to never turn your jet ski over in the water to remove rope, or other debris, that may have been sucked up by your ski. You must tow your jet ski back to the dock if this has occurred.
  • Release it: If you begin to fall off, or feel the craft beginning to roll, get off the jet ski as soon as possible and jump into the water. If the jet ski began to flip over, and you stay in the saddle, you will do nothing but aid the flipping process by remaining in place during the roll.

How do you reboard a jet ski?

How to Get Back on a Jet Ski After Falling – Reboarding Guide —

  • Stay calm. If you fall off a jet ski, the first and most important thing is to relax and stay calm. If you start to panic, you’ll find it harder to get back on the jet ski. Look around for where your jet ski is and swim over to it.
  • Turn the engine off. If you’ve fallen from your jet ski saddle, the safety lanyard probably shut the engine off immediately. But if your engine is still running for some reason, turn the engine off!
  • Flipping over the jet ski. If your jet ski has capsized, turn it upward in the right direction! You can find a sticker on the rear side of the jet ski. Read the instructions and follow them closely. If you don’t, you may force water into the jet ski’s engine which can cause a lot of damage!
  • Reboarding from the rear: Swim to the rear side of the jet ski for reboarding. Never try to get back on the jet ski from its side! They are too unstable and you may flip it over. The best practice is to reboard from the rear side in all cases!
  • Use the reboarding step. Most of the jet ski models today are equipped with a really cool feature called the reboarding step. You can find this unit on the rear side of the jet ski, and you can simply fold it down if you want to use it. Don’t worry; these steps are usually very convenient and covered with a knee-friendly surface.
  • Climbing up to the jet ski: Grab the jet ski’s passenger handrails; you can find them on the back of the saddle. Once your knee and feet are on the reboarding step, pull yourself up to the swim platform. It’s quite similar to how you climb up a ladder from a swimming pool. Depending on its size, you may find the jet ski a little unstable during the process. But don’t worry; just stay calm and try to keep your balance!
  • Consider a jet ski ladder. If you lack the upper body strength to pull yourself back up on the jet ski after a fall, you can also consider a special jet ski ladder that can be attached to the rear side.
  • Restart the jet ski. Once you are onboard, simply sit on the saddle, attach your safety lanyard and start the engine.

Which of the following is one of the legal requirements while operating a PWC?

Online Boating License & Boaters Safety Course Accredited by NASBLA My Profile Previous Search Close PWC are considered vessels and must comply with all safety equipment such as visual distress signals, life jackets, navigation lights, and sound producing device. In addition to the requirements previously stated applicable to all motorized vessels: 

  • Each person on a PWC or being towed by a PWC must wear a USCG approved PFD type I, II, III or V
  • Inflatable PFD are prohibited for personal watercraft use
  • The law requires anyone operating a PWC equipped with a lanyard cut-off switch to attach the lanyard to his or her person, clothing or life jacket. Operating a PWC equipped with a self-circling device is prohibited if the device has been altered
  • Maneuvering a PWC by weaving through congested vessel traffic, jumping the wake of another vessel unreasonably close or when visibility around the vessel is obstructed, or swerving at the last possible moment to avoid collision is classified as reckless operation of a vessel (a first-degree misdemeanor)
  • It is illegal for a person under the age of 14 to operate a PWC
  • A person must be at least 18 years old to rent a personal watercraft in Florida.
  • It is unlawful for a person to knowingly allow a person under 14 years old to operate a personal watercraft (a second-degree misdemeanor).
  • Personal watercraft may not be operated from 1/2 hour after sunset to 1/2 hour before sunrise, even if the PWCE is equipped with navigation lights. Remember, both federal and state law requires the use of navigation lights during periods of inclement weather and periods of reduced visibility, including the ½ hour before sunrise and the ½ hour after sunset.
  • You may not carry more passengers than the number for which the craft was designed to carry by the manufacturer. When towing someone on a tube or on water skis, the PWC must have the appropriate capacity to accommodate the operator, the observer, and the person being towed.


Which item is not required on a PWC?

Before You Ride —

  • Familiarize yourself with the owners’ manual and all safety warnings, paying particular attention to the operation of the jet jump.
  • PWC manufacturers recommend neoprene shorts or wetsuits to protect lower-body openings from impact with the water during a high-speed fall or the powerful thrust produced by the pump.
  • Never attempt to board when the engine is running, and keep loose clothing and long hair clear of the pump intake.
  • As with any type of boating, thoroughly understand boating laws and the rules of the road. Many states impose stricter age restrictions on personal watercraft use. Check local boating laws for the specifics in your area.
  • Different size PWC have different passenger and weight capacities; exceeding either could negatively affect the handling of the craft.
  • Familiarize yourself with the handlebar steering, throttle control and safety lanyard. Never operate a PWC without the safety lanyard attached to both craft and driver’s wrist or life jacket. Remove the lanyard whenever the craft is unattended to prevent unauthorized use.
  • Driver and passengers should always wear a Coast Guard-approved life jacket.
  • Eyewear will block the force of wind and water spray that could impair vision.
  • Gloves and footwear offer welcome additional grip and traction.
  • Wetsuits or windbreaker-style jacket/pant combos are advisable for cooler weather because PWC riders are far more exposed to the elements than the typical boater.


What is the leading cause of PWC accidents?

Preventing Accidents — Be aware of what is around you. The leading cause of PWC accidents is striking an object (usually another PWC). If you are operating your PWC in a congested area, slow down and look at what the boats around you are doing. To avoid being struck yourself, always look for other boats before making sharp or sudden turns.

Because PWCs are so small and maneuverable it is best to always give the other boats the right of way. Larger boats may not see you, and may not be able to get out of your way in time to avoid contact. Keeping a proper lookout can save your life.

As with any boat, operate at a safe speed. It is very easy to get thrown from a PWC, especially if you hit wakes or turn too quickly. Operating at a safe speed for the conditions will lower the risk of an accident. If you lend your PWC to a friend, make sure they know the Rules of the Road and how to operate your PWC.
