How Much Does A Jet Ski Weigh? [Towing & Dock]

Are you planning to hit the water on a jet ski and wondering about the weight factors involved?

Whether you’re a seasoned rider or new to the world of jet skis, understanding their weight and the weight of jet ski trailers is important for a smooth and safe experience.

In this guide, I’ll delve into the weights of various jet ski models from leading manufacturers like Sea-Doo, Yamaha, and Kawasaki. I’ll also explore the weight considerations for jet ski trailers and provide valuable insights into towing gear, trailer dimensions, and safety tips. So, let’s dive in and explore the world of jet ski weight to ensure you have all the necessary information for towing, docking, and enjoying your thrilling adventures on the water.

Jet Ski Weight

A jet ski weighs between 375 and 1,089 pounds. The average jet ski weight is 732 pounds.

The lightest standup jet ski is the Yamaha SuperJet at 375 pounds. The lightest sit-down jet ski is the Sea-Doo Spark 2up at 410 pounds. The heaviest jet ski is the Kawasaki ULTRA 310LX at 1,089 Pounds.

The advertised weight of a jet ski doesn’t always include fuel, gear, and other items that go along with a fully ready PWC. You also need to keep in mind the weight of the trailer if you’re pulling them with your truck.

How Much Does A 3-Seater Jet Ski Weigh?

The weight of a 3-seater jet ski ranges from 425 to 1,100 pounds.

A 3 person, or a 3-seater jet ski, is the most common seating capacity, with a 2-seater next. There were a few watercraft that had 4 person capacity, but they’re rare to see these days. You also have 1 person capacity, but mostly on standup jet skis.

How Much Does A 2-Seater Jet Ski Weigh?

The weight of a 2-seater jet ski ranges from 375 to 800 pounds.

A 2-seater jet ski is less common, mostly lower-end and racing watercraft have a 2 seater capacity.

  • 4-Place – Four jet skis, with a combined weight of 4,200 pounds.

Jet Ski Trailer Dimensions

If you’re storing your jet skis on a trailer in a garage or storage unit, you’ll need to know the dimensions that I cover here.

Tip: If you’re going to get a trailer and have the option of a Triton Aluminum Trailer, then get it. Sea-Doo, Karavan, and many others make trailers, and they work just fine. But I always have the best luck with Triton Trailers. I find that the Aluminum trailers like the Triton’s are lighter and hold up better to rust.

Why Jet Ski & Trailer Weight Is So Important?

It’s not always obvious why the weight of a jet ski, its trailer, or both is so important.

Below, I’ve listed why jet ski weight and trailer weight is so important.

  1. Truck capacity – Your tow vehicle has a rated capacity that it can haul and stop safely. It’s important you know this number and take into consideration not only the jet ski weight, but also its trailer along with any gear, too.
  2. Lift capacity – If you keep your jet ski on a drive-up lift or hoist, you will need to know the weight of your jet ski to use the lift properly. Lifts come in different sizes and rated for different weight capacity, so it’s important you get one rated for your jet ski.
  3. Don’t overload your trailer – A jet ski trailer can only hold so much weight. It’s not only the weight of the jet ski, but all the gear and fuel you carry needs to be considered.
  4. Don’t over load your jet ski – You don’t want to overload your jet ski weight capacity, as covered here.
  5. Fuel efficiency – The weight of a jet ski can impact its fuel efficiency. Heavier jet skis will require more power to propel through the water, resulting in increased fuel consumption. Understanding the weight of your jet ski allows you to make informed decisions regarding fueling and plan accordingly for longer rides. It can also affect the fuel efficiency of your tow vehicle too.
  6. Safety Considerations – Proper weight distribution is crucial for safe towing. Understanding the weight of your jet ski and trailer helps ensure that you distribute the load evenly, maintaining stability and reducing the risk of accidents or trailer sway during transportation.
  7. Maintenance and Repairs – Knowing the weight of your jet ski and trailer is essential for proper maintenance and repairs. It allows you to know what is the proper tire and axle that is rated for the weight of your jet ski trailer.
  8. Laws and regulations – Trailers in some places around the world require brakes after a certain weight capacity. So, knowing the weight of your jet ski and gear will play a role in what trailer you can buy.

Gear Needed For Towing A Jet Ski Trailer

If you’re going to be towing a jet ski on a trailer, you’ll not only need to worry about weight, but the proper towing gear. Here is a list of items you should have if you want to tow any trailer…

  1. Hitch/Receiver – Every car or truck needs a hitch to tow a trailer. The hitch is the part that goes into the receiver. Some trucks or SUVs will come with a hitch, but if you don’t have one, then you need to have one installed.
  2. Ball Mount – After you get the hitch, you’ll need the ball mount and ball. The ball mount supports the tow ball and slides into the receiver tube.
  3. Ball – The ball is what the trailer rotates on and what you connect to your truck. Jet ski trailers use either a 2-inch or a 1 7/8 inch ball. The 2-inch ball is the most common, especially for newer trailers. Not sure which one to get? Get both, here is a ball mount combo with both ball sizes. *
  4. Receiver Lock – You may lock your trailer down at the coupler, but it’s nothing for a thief to unlatch the ball mount and plug that into their truck and drive away with your trailer. With a receiver lock like this one here*, you can keep that from happening.
  5. Light Adaptor – You know the number one thing most of my customers would forget to buy when picking up their new jet ski on a trailer? The adaptor for the lights. Jet ski trailers use a flat connector, and most trucks built within the last 20 years use the round light connector. In most states, you need lights on your trailer if you want to be legal. You must get a trailer light adaptor like this one here*, so it works with your jet ski trailer.

What Size Ball?

Jet ski trailers come in two ball sizes, a 2 inch and a 1 7/8 inch ball.

You’ll know what size ball you’ll need for your tow vehicle as the trailer will say the size you need right on top of the coupler as pictured below.

It’s important you use the right size ball for your trailer. While a 1 7/8-inch ball will work on a 2-inch trailer, it’s dangerous to do so, and you run the risk of the trailer falling off your vehicle.

What To Do With Trailer Chains?

It’s important you cross the chains on your trailer in case the trailer comes off the ball, the chains will cradle it.

If the chains are dragging, then twist them a few times to raise them up.

Can A Car Tow A Jet Ski?

With the proper hitch and accessories, most cars can be adapted to tow a watercraft just fine. But you must be very strict about tow capacity when it comes to a car, since it can’t tow as much as a truck.

When it comes to jet ski weight along with trailer weight, there is a lot more to consider with using a car to tow them. That is why I wrote this post about using a car to tow a jet ski and trailer.

Can You Carry One Jet Ski On A Double Trailer?

You can tow one jet ski on a double trailer by itself, as covered in this post here.

How To Back Up A Jet Ski Trailer

Backing up a jet ski trailer can be hard, especially if it’s a single trailer. Hooking up the trailer to your truck can be hard, too.

To help, I’ve created a guide showing you how to launch a jet ski from a trailer that covers all this and more.

To make backing up the trailer easier, you can buy boat trailer guides*. These guides are made for boats to guide them in from the water, but if you get long enough ones, it also allows you to see where the sides of your trailer are when backing up. Plus, it helps with loading the ski too as it can keep the rear from swinging away when you’re trying to load up.

More On Jet Ski Trailer Accessories

Did you know many trailers you buy won’t have a tongue jack? A tongue jack is needed if you want to easily get the trailer off the ball of your truck.

There are many other accessories you should look into getting for your jet ski trailer. I have a list of the must-have trailer accessories here.

  1. Thanks…very informative. One question; Is there a way to know the tongue weight based on the weights you’ve given here?

    Thanks, Terry

    • The weights given in the post are not exact numbers, they can vary depending on the watercraft. The tongue weight can also vary too and there is no exact number to give. If anything, I like having a heavy tongue than a light one to keep bouncing from happening. To help with the weight of the tongue I get a Tongue Jack which saves the back. As a general rule, always assume the trailer is tongue light when approaching it. I’ve been smacked and trailers noses flung up in the air because the trailer was light when got on it or took it off the ball. Better to be safe than sorry.
