What Affects The Weight
- Hull Material: The hull’s material and construction method play a significant role in its weight. For instance, fiberglass is a common material used in many jet skis because of its balance between strength and weight. Some newer models may use advanced composites to reduce weight further.
- Engine Size and Type: Larger engines will generally weigh more than smaller ones. Additionally, the type of engine (2-stroke vs. 4-stroke) can influence weight. Four-stroke engines, common in newer jet skis, tend to be heavier than two-stroke engines.
- Fuel and Oil: The weight of a full tank of fuel and oil can significantly increase the overall weight of the jet ski. For instance, a gallon of gasoline weighs about 6-7 pounds.
- Battery: Batteries, dual battery systems, can add to the weight.
- Additional Equipment and Features: Features like reverse systems, braking systems, sound systems, coolers, and larger storage compartments can add to the jet ski’s weight.
- Aftermarket Modifications: Any modifications or aftermarket parts added to the jet ski can influence its weight. This includes larger impellers, reinforced hull components, or additional accessories.
- Water and Debris: After usage, water can become trapped in various parts of the jet ski, adding to its weight. Additionally, debris or marine growth on the hull can also contribute to weight over time.
- Towing and Wake Features: Some jet skis are equipped with features for towing (like for wakeboarding or tubing) which can add to the weight.
- Cooling System: Some jet skis use a closed-loop cooling system that uses coolant, whereas others use direct lake or seawater. The type and amount of coolant or water can influence the jet ski’s weight.
Weight And Costs
You’ll find that the cheaper the watercraft, the lighter it is, and the opposite is true.
The more affordable sit-down watercraft like the Sea-Doo Spark and Yamaha EX are some of the lightest watercraft on the market. While the heaviest watercraft are also the most expensive options, though you do have middle to high prices jet skis that are heavy, like the Sea-Doo Explorer Pro.
Trailer Weight
When it comes to jet ski trailer weight, there are two numbers to worry about, the weight of the actual trailer and what weight the trailer can hold.
The material that jet skis are made of can affect the weight too. An all-aluminum jet ski trailer will weigh less than a painted steel or galvanized trailer.
| Trailer Type | Weight (lbs) |
| Single | 150 to 300 |
| Double | 300 to 400 |
| 4-Place | 1000 to 1500 |
Trailer Tongue Weight
Tongue weight is the weight that is on the front of the trailer that connects to the truck.
It’s important to get this number right.
- A trailer that is tongue light means it’s easy to lift.
- A trailer that is tongue heavy means it’s hard to raise.
I know many people want the trailer to be easy to lift, but they can overdo it. You need weight on the trailer’s tongue to keep the trailer from bouncing too much. A light tongue means more weight is at the rear of the trailer. This can cause the trailer to sway at high speeds and more likely to pop off the ball or wreck.
Trailer safety is very important, here is why. More trailer safety tips can be found here.
The opposite is also true; you don’t want the nose of the trailer to be so heavy you can’t lift it off the ball of your truck.
No one should be lifting their jet ski off the ball without the assist of a tongue jack. I’ve pulled plenty of muscles learning this the hard way. You should be chocking or locking the wheels off with a block of wood when taking it off the trailer, too, as this guy learned the hard way.
