Fuel efficiency depends on the jet ski's weight and performance
The fuel efficiency of a jet ski depends on a variety of factors, including its weight and performance. The average jet ski can travel around 60 to 120 miles on a single tank of gas, which typically holds between 5 and 21 gallons of fuel. The engine size, supercharger, weight, riding conditions, and number of passengers all impact the range that a jet ski can travel.
The weight of a jet ski affects its fuel efficiency because it determines the size of the fuel tank and how far it can go. Heavier jet skis with larger fuel tanks may be able to travel farther distances but may not be the most fuel-efficient. On the other hand, lighter jet skis with smaller engines tend to be more fuel-efficient, such as the Sea-Doo Spark and Yamaha EX models. These models have smaller fuel tanks and lower horsepower, resulting in reduced fuel consumption.
Performance-wise, jet skis with higher horsepower engines, such as those over 250 HP, tend to have lower fuel efficiency, burning over 22 gallons per hour (GPH) at wide-open throttle (WOT). In contrast, jet skis with smaller engines and lower horsepower will have better fuel efficiency. For example, the 60HP Sea-Doo Spark base model has a fuel efficiency of 2.4 GPH at cruising speeds, while the larger engine models of the same brand can reach 6 GPH at WOT.
Riding conditions also play a significant role in fuel efficiency. Smooth and calm water conditions allow jet skis to travel farther on less gas, whereas choppy waters require the watercraft to work harder, increasing fuel consumption. Additionally, the number of passengers and gear loaded onto the jet ski contributes to its curb weight, which in turn affects fuel efficiency.
It is worth noting that fuel efficiency may be challenging to measure accurately, as it depends on various factors and can vary even within the same model. However, by considering the weight, engine specifications, and riding conditions, one can make informed decisions about fuel efficiency when choosing a jet ski.

Jet ski fuel consumption at full throttle
Jet ski fuel consumption varies depending on several factors, including the jet ski's performance, weight, fuel capacity, and weather conditions. Fuel consumption at full throttle is typically the most inefficient, as any motor vehicle burns the most fuel at the highest speed.
For example, the Sea-Doo GTI 4-stroke can burn through a full tank in about an hour when ridden at full throttle. The Yamaha EX Waverunner burns nearly eight gallons per hour, while the STX-15F Jet Ski consumes 14 gallons per hour. Flagship models can burn as high as 20-25 gallons per hour.
The average jet ski gets 3-5 MPG at full speed, depending on the jet ski's performance, weight, and weather conditions. At best cruise speed, an average jet ski gets 8-10 MPG, allowing for a ride time of 4-7 hours before needing to refill. The best cruise speed, which is the most fuel-efficient speed, is generally around 25-30 mph for most PWCs.
To calculate the fuel consumption in gallons per hour (GPH), use the formula: GPH = gallons of gas burned/hours ridden. To calculate miles per gallon (MPG), use the formula: MPG = miles ridden/gallons of gas burned.

The average jet ski's fuel efficiency
The fuel efficiency of a jet ski depends on several factors, including the engine size, supercharger, weight, riding conditions, and riding style. The jet ski's weight and performance, weather conditions, and tank size also influence fuel efficiency. Generally, the larger the jet ski, the better it is for longer distances, but it may not be the most fuel-efficient.
The average jet ski can go around 60 to 120 miles on a single tank of gas, which equates to around 2 hours of full-throttle riding. The average jet ski uses about 10 gallons at wide-open throttle (WOT), resulting in an average of 1.8 hours at full throttle. Some jet skis can go as far as 170 miles on a single tank of gas.
The fuel efficiency of jet skis is often measured in gallons per hour (GPH) rather than miles per gallon (MPG). An average jet ski burns around 3 to 4 gallons of gas per hour at the best cruise speed, which is around 25 to 30 mph for most PWCs. This means you can ride for 4 to 7 hours on a single tank of gas. The most fuel-efficient jet skis have smaller engines, like the Sea-Doo Spark and Yamaha EX. The 60HP Sea-Doo Spark base model consumes about 2.4 gallons per hour at cruising speeds.
However, when ridden at full speed, jet skis can be very inefficient, with fuel efficiency dropping to 3 to 5 MPG. Some jet skis can burn through 8 gallons per hour, and the most powerful models can even burn 20-25 gallons per hour.

Factors affecting a jet ski's range
Several factors influence the range of a jet ski, and understanding these elements is crucial for planning the perfect trip. Firstly, the engine size and type impact fuel efficiency. For example, a 2-stroke engine will have different fuel consumption characteristics than a 4-stroke engine. The horsepower and weight of the jet ski also play a role, as higher horsepower may result in increased fuel usage, and heavier models may be less fuel-efficient.
Fuel capacity is another critical factor. Jet skis typically have fuel tanks ranging from 5 to 21 gallons, with 18 gallons being the most common capacity. The larger the tank, the greater the potential range, but this also depends on the fuel efficiency of the jet ski. Some jet skis, like the Sea-Doo GTX Limited, have a fuel capacity of 18.5 gallons and can travel up to 185 miles on a full tank.
Riding conditions and rider behaviour significantly affect the range. Riding aggressively with frequent acceleration and high speeds will consume more fuel. Additionally, the rider's weight and any extra cargo can impact fuel efficiency. Riding with the current and wind can help extend the range, while areas with heavy boat traffic may reduce efficiency due to the wake. Maintaining a steady, moderate speed is generally more fuel-efficient.
Regular maintenance and engine care are essential for optimizing the jet ski's range. Cleaning the engine, changing the oil, and checking the spark plugs can improve fuel efficiency. Winterizing the jet ski appropriately maintains its performance. The quality of fuel used also matters, with high-quality gasoline without ethanol potentially improving fuel output compared to lower-quality fuels.
Lastly, the jet ski's size influences its range. Larger jet skis tend to have better long-distance capabilities but may not always be the most fuel-efficient. Electric jet skis, such as the Taiga Motors Orca, offer unique trade-offs, emitting no pollutants but potentially having a restricted range per charge compared to gas-powered jet skis. Overall, understanding these factors and planning accordingly will help maximize the range of a jet ski.
