Average PWC Gas Tank Sizes
Before we go into details about the average PWC gas tank sizes, don’t forget to check the fuel consumption specs as well as the calculated MPG for each model.
If you look at the average numbers,
the size of tanks on different
PWC models is between 5-20 gallons,
with an average of 15 gallons.
You may be curious about how many hours can you ride with 15 gallons in your tank. Take into account the fuel consumption of an average personal watercraft model:
An average watercraft can
run for 1-2 hours on full throttle
with a full tank of gas, while burning around
10-15 gallons of gas.
But again, these are average numbers, and the numbers vary from model to model.
The rule of thumb here is that supercharged PWCs have higher fuel consumption, while the non-supercharged models are much better on gas. If you’d like to know more about PWC superchargers, don’t miss our post on this topic.
Performance and displacement are other factors when it comes to PWC fuel consumption. The more horsepower and the larger displacement there is, the higher the gas consumption. You have to feed those horses!
The Average Usage
But will you ride at full throttle all the time? If you’re an experienced rider, you probably know the answer.
If you’re a beginner, you have to know that riding at full speed and doing tricks are quite exhausting, so you’ll hardly go full speed on long distances!
Because of this, you can typically ride much more on one tank of gas.
An average watercraft burns
3-4 gallons of gas per hour at best cruise speed.
This means you can ride around
4-7 hours on one tank of gas.
If you’re looking for the lowest gas mileage, currently the Sea-Doo Spark with 60 HP is the most fuel-efficient PWC model on the market. Lowest displacement + lowest performance + non-supercharged engine = lowest gas consumption!
This means you can ride the whole weekend even on one tank of gas (7.9 gallons). On one hand, you can’t expect the same top speed and acceleration on the Spark, which is what performance PWCs can offer you.
On the other hand is the Sea-Doo RXT-X 300 which can burn 25 gallons in a single hour. With a gas tank size of 18.5 gallons, you can empty your tank completely in around 45 min!
Sea-Doo Gas Tank Sizes
Sea-Doo gas tank sizes start from 7.9 gallons, and you can find the same tank in all Spark models. In the past, surprisingly, all of the other models came with the same 15-9 gallon fuel capacity!
The only exception is the Sea-Doo Fish Pro 2020, which is equipped with a gas tank of 18-5 gallon capacity. PWC fishing always means longer rides, so it’s a nice addition from Sea-Doo!
The good news for 2020 is that several other Sea-Doo models are equipped with this larger gas tank with 18.5 gallon capacity. So, finally you can find this tank in these Sea-Doo models:
– 7-9 gallon capacity: Sea-Doo Spark Family
– 15.9 gallon capacity: GTI line, Wake 170, GTR 230
– 18.5 gallon capacity: GTX Family, RXT-X, RXP-X, Wake Pro 230, Fish Pro
If you haven’t looked deep inside your PWC’s hull, then you probably haven’t seen your tank. If you’re interested in what it looks like don’t miss this video:
Yamaha WaveRunner Gas Tank Sizes
Yamaha WaveRunner gas tank sizes vary widely depending on the model. The Yamaha Superjet (stand up) has the smallest gas tank with 4.8 gallons.
When it comes to fuel gauges on PWCs, it’s good to know that they usually show the tank is empty while there are still a couple of gallons left in them. For example, on larger WaveRunner models (with the 18.5 gallon tanks) you can expect 5-6 gallons of gas in the tank when you see “empty” on your gauge.
Manufacturers set the gauges with this safety trick for good reason, as too many riders empty their tanks and get stuck on the water.
Jet Ski Gas Tank Sizes
When it comes to Kawasaki, their models have the largest fuel capacity on the market. Kawasaki Jet Ski gas tank sizes go from 6.1 gallons to 20.6 gallons, with the average being 18.5 gallons.
All of the other Kawasaki Jet Ski’s tank sizes are the same, with a whopping 20.6 gallons. (Ultra Line, and the new STX 160 Line)
Krash PWC Gas Tank Sizes
When it comes to the Krash PWC gas tank size and engine, things are pretty simple.
All of their models are equipped with the KV997 two-stroke engine, and a 4.75 gallon fuel tank. If something works, why would they use anything else?
Extra PWC Fuel Cans
There are many cases when the factory-installed gas tank size is not big enough, and you have to take extra fuel with you.
These cases are typically on fishing trips or longer jet ski tours. When it comes to extra PWC fuel cans (known as PWC jerry cans, or PWC gas cans), you can choose from several good solutions.
Many beginners think that it’s a good idea to place a smaller fuel can into the storage compartment of the craft. Never do that; it could be really dangerous!
If gas leaks from the can into the hull, the vapors from the leaking gas can easily cause an explosion!
If you want to take extra gas with you on your PWC,
the most common place to store it is the rear platform.
You may wondering how can you attach the extra fuel cans on this platform? Let’s check your opportunities one by one!
Attaching a PWC Jerry Can
The fastest and easiest way is to attach a PWC jerry can to your rear platform to fix them with a pair of traps. If you don’t need extra fuel regularly, you can consider this easy solution.
PWC Fuel Can Racks
If you bring extra fuel with you regularly, you will need a PWC fuel can rack. There are several good racks available on the market, and you can consider a simple PWC rack which can accommodate extra fuel cans, coolers or even bags.
If you are thinking of fishing, then PWC fishing racks are for you. They look similar to the simple racks, but they’re also equipped with a few rod holders to store your fishing rods. You can store your extra gas cans in these racks, or even on the side of them, depending on the model.
PWC Saddle Bag Fuel Cans
The other place to store some fuel cans is a PWC saddle bag.
If you have no passengers with you and also don’t want to add extra weight to the rear platform, this solution is for you. What’s more, you can store extra gear in the bags as well! Additionally, you don’ t have to drill into the fiberglass to affix it to your craft. Any drawbacks?
It can only hold smaller PWC gas cans, so your extra fuel capacity is limited.
Sea-Doo LinQ System
Do you have a Sea-Doo PWC? If yes, you probably heard about the unique Sea-Doo LinQ system.
In a nutshell, it’s a quick-attach rear platform cargo system which you can attach to specially designed Sea-Doo coolers, fuel cans or even storage boxes.
The LinQ system is a must-have accessory for every Sea-Doo owner, so if you don’t have this system, it’s highly recommended you install it!
Auxiliary PWC Fuel Tank
All solutions above are pretty good, except for one aspect. When you run out of gas and it’s time to refuel your craft, you have to open the cans and flush the fuel into the PWC.
Doing this, there is an obvious chance of fuel spillage or dripping, especially if you have heavier cans. These issues can be dangerous for the environment, and can damage the PWC as well. You have to always pay extra attention to this as fuel spillage could be an issue, especially if you ride in protected areas.
If you are an experienced long-distance rider, you can consider an auxiliary PWC fuel tank. This means you can connect your auxiliary tank to the main tank with a hose. It’s a really convenient and safe way to carry extra fuel on your PWC.
It’s clear that this solution is not for everyone, but if you’re thinking about a system like this, don’t hesitate to check a great step-by-step guide how to install one at Watercraft Journal.
As there are several models on the market; the Sea-Doo, WaveRunner and Jet Ski gas tank sizes vary widely.
The tank capacities start as low as 4.8 gallons and go up to 20.6 gallons, with the average being 15 gallons. If you ride your PWC on full throttle, you can empty your tank in 1-2 hours depending on the model. On the other hand, you can ride 5-7 hours if you ride your craft at best cruise speed.
Having safety in mind, the rule of thumb is to always use the 1/3 rule for fuel consumption during your rides. This means you should calculate 1/3 gas usage to go out, and 1/3 to go back.
This will leave 1/3 of your tank in case your way home takes longer than expected due to waves, drift or even wind. Also, it’s wise to inspect fuel tanks and fuel lines regularly to avoid explosions or accidents due to gas vapors in the engine compartment.
Also, don’t forget that large fuel can(s) installed on the rear platform can definitely affect the handling of the PWC, so be careful on your first ride with the extra cans!
Because of the extra weight – especially if you have extra gear or passengers with you beyond the cans – don’t forget to check your PWC’s weight limit.
This was our short review about PWC gas tank sizes, as well as extra fuel cans. We hope it was helpful!
