Jet skis are notorious for being fuel-inefficient compared to cars. This is due to the high-performance engines jet skis are typically equipped with, which require a lot of fuel to overcome resistance and move the hull through the water. The type of engine, riding conditions, and speed all play a role in fuel consumption, with faster speeds and choppy waters causing the vehicle to burn through fuel more quickly. The average jet ski uses 3-4 gallons of gas per hour, with some jet skis using up to 25 gallons per hour at full speed. The Sea-Doo Spark is one of the most fuel-efficient jet skis on the market, using only about 2 gallons of gas per hour. The average cost of filling up a jet ski is around $50, with the average PWC owner paying about $1,200 a year for fuel.

Jet ski fuel consumption vs mileage
Jet ski fuel consumption and mileage are important considerations when purchasing a watercraft. Jet skis are known to be fuel-inefficient compared to cars, with an average mileage of 3-4 miles per gallon (MPG) or 7-10 MPG with reasonable use, resulting in a fuel range of 60-120 miles or 70-150 miles, respectively. In contrast, the average car achieves 25 MPG. Jet ski engines need to produce a lot of energy to overcome resistance when moving the hull through the water, and they often have high-performance or supercharged engines that consume more fuel. The fuel consumption of a jet ski is typically measured in gallons per hour (GPH), and it can vary from 2 to 25 GPH depending on various factors.
The type of engine impacts fuel consumption, with 2-stroke engines being less fuel-efficient than 4-stroke engines. Additionally, more cylinders and larger displacements increase fuel consumption. Supercharged engines, commonly found in high-performance or luxury jet skis, consume significantly more fuel and require premium gasoline (91 or 93 octane). The Sea-Doo Spark, for example, is known for its fuel efficiency, achieving 2 GPH at wide-open throttle.
Riding conditions also play a crucial role in fuel consumption. Smoother water allows the jet ski to travel farther on less gas, while choppy water increases fuel usage. The speed at which the jet ski is operated is another factor, with cruising speeds of around 35 mph considered efficient, while higher speeds result in rapid fuel burning. The number of hours spent riding and the loading of the jet ski can also impact fuel efficiency.
The size of the jet ski and its engine capacity influence fuel consumption and mileage. Smaller recreational jet skis tend to be more fuel-efficient due to their compact size and lower gas consumption. Larger jet skis, particularly those with more powerful engines, will have higher fuel costs. The cost of fuel for a jet ski can vary, with an average of around $50 per tank, and the annual fuel expense for a jet ski owner is approximately $1,200.

Fuel type and engine specifications
The fuel consumption of jet skis depends on several factors, including the type of engine, riding conditions, and speed.
Most jet skis run on gasoline, but the required type of fuel varies across models. Some jet skis require premium fuel (91 or 93 octane) if they are supercharged. High-performance engines are very particular about the fuel they use and will indicate a check engine light if the fuel does not meet specifications. It is important to use the specified gas in a jet ski as using a different octane level can lead to error messages, reduced performance, or even engine damage. Ethanol gasoline is generally best avoided, as it can damage fuel lines over time, especially in 2-stroke engines. However, 4-stroke jet skis can typically run on fuel with up to 15% ethanol.
The engine type plays a significant role in fuel consumption. 2-stroke engines tend to be harder on fuel than 4-stroke engines. Additionally, more cylinders and larger displacement result in increased fuel consumption. Supercharged engines consume significantly more fuel and require more expensive fuel. High-performance and luxury models are generally less fuel-efficient than average Rec-Lite or Recreation PWCs.
Riding conditions also impact fuel efficiency. Smoother water allows the jet ski to travel farther on less gas, while choppy water makes the watercraft work harder. The riding speed also affects fuel consumption, with higher speeds leading to increased fuel usage.
The fuel efficiency of jet skis is typically measured in gallons per hour (GPH) rather than miles per gallon (MPG) because it can be challenging to track distances accurately on the water. The average jet ski uses around 3-4 gallons of gas per hour, with some sources stating an average of 6-8 gallons per hour at cruising speeds of around 35 mph. The most fuel-efficient jet skis are typically the entry-level Rec-Lite models, burning about 2-3 gallons at their best cruise speed. In contrast, the least fuel-efficient models are the Performance and Luxury machines, with some jet skis capable of burning up to 20-25 gallons per hour at full speed.

Riding conditions and speed
The amount of fuel a jet ski consumes depends on several factors, including riding conditions and speed.
Riding conditions can vary from flat water to surf or chop, and the fuel consumption will differ accordingly. For example, a jet ski may use 12.4 gallons of fuel in 2-3ft surf conditions with two people on board, whereas the same jet ski may use less fuel in flat water conditions with only one rider. The type of water (saltwater or freshwater) can also affect fuel consumption. Additionally, the weight of the rider and the number of people on board will impact fuel usage.
The speed at which a jet ski is ridden significantly affects fuel consumption. Jet skis are most fuel-efficient at their best cruise speed, which is typically in the range of 20-30 mph. At this speed, a jet ski can expect a fuel consumption of 3-5 gallons per hour, resulting in a fuel range of 70-150 miles. However, when ridden at full throttle, fuel consumption increases significantly. For example, a Yamaha FZR can burn 18 gallons of fuel in 45 minutes when ridden at full throttle, resulting in a fuel efficiency of around 4.4 miles per gallon. Similarly, a Sea-Doo RXP-X 255 can burn 18.2 gallons of fuel per hour at wide-open throttle, resulting in a riding time of about 53 minutes with a full tank of 15.9 gallons.
The type of engine also plays a role in fuel consumption. Two-stroke engines tend to be less fuel-efficient than four-stroke engines, with fuel consumption rates of around 8 gallons per hour at near-top speeds. However, at cruising speeds, a two-stroke engine may use around 4 gallons of fuel per hour. High-performance and supercharged engines also contribute to higher fuel consumption.
Overall, riding conditions and speed have a significant impact on the fuel consumption of a jet ski. Riding in challenging water conditions, carrying additional passengers, riding at high speeds, and using high-performance or two-stroke engines will all result in increased fuel usage.
