The Significance of Weight Limits on Jet Skis

A watercraft is the closest many of us will get to a motorcycle without as many dangers that come with a motorcycle. It’s a unique experience, often with power and speed found in supercars.

It’s no wonder more people keep joining the sport or testing it out by renting a few machines.

As the more people join the jet ski world, they may have certain questions. Things like, what is the weight capacity? Are they and the passenger too heavy? What about the gear they need to carry? Let’s answer these common questions below!

Key Points:

Far too many people don’t realize one important factor about jet skis. There is a weight limit for all models that you must not go over! This capacity varies between 350–600 pounds per jet ski, with fitting 1–3 riders.

When considering this number, you need to not only consider rider weight, but also the weight of the gear and fuel.

Why does It matter?

I’m often surprised by other riders being so care-free with the weight capacity. It’s there for a reason, and it’s not a suggestion!!!

Here is why you should not go over these numbers:

  1. The watercraft becomes unstable and more tippy.
  2. The watercraft is harder to steer and control.
  3. You’re more likely to get hurt getting on and off when over the weight capacity.
  4. The watercraft could sink, especially if you keep flipping it.

Greater Chance To Flip

Being over capacity means it’s more likely to flip over, or it can sink. A jet ski that flips over or sinking raises the chances of the engine hydrolocking or getting damaged! (Fixing a hydrolocked engine is expensive – it requires a lot of oil changes so long the engine didn’t blow)

More Dangerous

If you do get the PWC out on the water while it’s being over the weight capacity, taking a turn too sharp will cause you to roll over.

You can also lose control of the steering, causing you to get hurt or damage your PWC.

Falling off a jet ski doesn’t mean it will turn around and come back to you, either.

Please don’t confuse the weight of the watercraft with its “weight limits”. The weight of the watercraft is how much it weighs, but the limit is how much it can hold, which is 350 to 600 pounds.

All Gear And Riders

This weight capacity includes all gear and rider weights combined. If everyone and everything on the jet ski happens to go over that number, the watercraft is not safe and risk sinking, damage, or personal injury.


Even if you have a 3-seater, it doesn’t mean you can ignore the max capacity.

The max capacity includes the weight of all the riders, and if all 3 people’s weight is more than the max capacity, you can’t ride it safely.

The same is true the other way around, even if 4 people are under the capacity, you CAN NOT have 4 people on a 3-person watercraft.

Water patrol takes the seating number very seriously, especially when it comes to pull sports.

It’s also a bit tricky at times because many PWCs look like 2-seaters but fits 3 people. The honest truth is that most 3-seaters fit two normal-sized adults, and a 2-seater fits one normal-sized adult.

rear handles of GTX

I’m a 240-pound man, and I feel very confident riding a 3 or 2 seater spark by myself.

I’ve even ridden two of me on my 3 seater spark, it’s possible, and no one fell off.

But I would not dare put any more weight beyond that. I’ve also ridden 2up on a 3 seater GTI and had no issues with that; it felt a lot more stable than the 3-seaters Spark, that is certain.



I started working at a power sports dealership in 2007, I worked in parts, service counter, and as a technician before moving to sales in 2013. I created in 2014 to answer common watercraft questions I would get from people. Now managing the site full-time, I continue to provide advice and web tools for my readers about watercraft. I've owned several watercraft, with a Sea-Doo Spark as my current main PWC.


  1. I’m 315lbs. I’ve been able to get onto a jet ski in shallow water using the step on the back, but I’ve never had to do it in open water. My question is, on a 3up Spark with a step, would trying to get on it in open water cause it to sink in the back or would it be able to support me pulling myself up into it.

    Great articles by the way!

    • I’m 240 and when I try to get on a 3up Spark from the open water it’s quite hard. The rear end does take a dive and getting up is only half the battle as you have to balance it when getting up. It requires a lot of upper body strength because you’re soaking wet. The bigger models like the GTI’s or GTX are less of an issue, those Sparks can be tricky.

  2. Does the weight limit (ie. 600 on RXT300) include the weight of the fuel? I thought it was just humans and cargo.
