How Much Does A Jet Ski Weigh?

Jet skis come in a wide range of sizes and models, even if you narrow your answer down to the three prominent market leaders in the personal watercraft industry: Yamaha, Kawasaki, and Sea-Doo.

But it is essential to know how much your jet ski weighs if you plan to attach it to a trailer or take it in your truck.

Average Jet Ski Weight

The average jet ski weight is difficult to measure because it depends on which vehicle you are measuring. Naturally, smaller jet skis will weigh less than larger jet skis.

It is better to think of the average jet ski weight as a range. When you compare the most popular jet ski models from the three leading manufacturers mentioned above, you get an average jet ski weight of roughly between 300 and 950 pounds. That is a lot of variation, so it is important to look at your jet ski manufacturer’s manual or instructions before loading it into your truck. Hence, you know whether your vehicle can handle transporting it.

Examples of Jet Ski Model Weights:

  • Yamaha SUPERJET — around 306 pounds
  • Sea-Doo Spark series — 400 to 500 pounds
  • Kawasaki SX-R — approximately 503 pounds
  • Yamaha EXR and EX series —500 to 600 pounds
  • Sea-Doo GTI series, Wake 170, GTX 170 — 600 to 800 pounds
  • Yamaha VX Series and GP1800R — 600 to 800 pounds
  • Sea-Doo RXT, RXP, GTX, and GTR series — 800 to 900 pounds
  • Yamaha FX Series — 800 to 900 pounds
  • Kawasaki Ultra 310 Series — 900 to 950 pounds

Always verify the information provided by your jet ski's instruction manual about your watercraft's overall weight before taking it anywhere, even when using the above chart. Your jet ski might weigh more or less than the above examples, even if it belongs to one of those series.

Additional Weight Bumps

In addition to the “true” or raw weights of the above jet ski models, you also have to consider the weight of fuel and oil. It doesn’t sound like a lot, but it can add up to more than you might think.

For instance, fuel weight is usually around six pounds or so per gallon. Oil weight is approximately seven pounds or so per gallon. If your jet ski has a full fuel tank, you will need to account for the resulting weight when making any calculations.

Furthermore, the other items you bring on your jet ski trip could add to the total weight of your setup.

Gear/Accessories

Many of the best jet skis have various storage compartments where you can store fuel, accessories, and gear. It is all too easy for you to add another fifty pounds or so to your jet ski through the storage compartment, and larger jet ski compartments can allow you to store hundreds of pounds of gear.

Examples of several items you might include in your jet ski’s storage compartments are anchors, bumpers, lifejackets, ropes, and more. Be sure to include these items when figuring out how much weight you need to pull behind your car or truck.

Trailer

If you plan to take your jet ski to the water by towing it, remember that you can’t just calculate the jet ski’s weight, plus the stored items. You also need to consider the weight of the trailer you plan to tow with the jet ski.

On average, single watercraft jet ski trailers can weigh anywhere between 170 and 275 pounds. Larger trailers that fit more than one jet ski can easily weigh up to 1,200 pounds in total, especially when the trailer in question has dual axles.

As with the jet ski itself, be sure to check out the instruction manual or manufacturer’s booklet with any jet ski trailer so you can adequately calculate the total weight you will be towing behind your personal vehicle.
