As important as the horsepower is, it’s not the only factor to consider when it comes to engine performance. Power-to-weight ratio has a great effect as well.Though the current unit of measure for horsepower is no longer equivalent to Watt’s calculation, we are indebted to him for the creation of this useful term. Sea-Doo’s most powerful models arrive with 310 horsepowers, a number which is over 5 times the HP of 1988. The amount of improvement is truly staggering. Yamaha’s best watercraft performance model is a top pick for racers and tuners. But how can this be when their engine is so much lower than the finest Kawasaki?Yet, Sea-Doo family was not alone in striving for constant horsepower growth. Competitors joined the race, throwing resources at reaching maximum strength. The current top performance skis are:Rec-lite and Recreation models are the largest sized options in the group and generally have a ratio of 0.14-0.24. Engines for this type of machine are naturally aspirated (not super-charged) and models weight in around 400-800 pounds. Picture a watercraft with 200 hp and a weight of 200 pounds. Because the horsepower and weight are the same number, the power-to-weight ratio is 200/200 which can also be expressed as 1/1 or 1. Yamaha, however, simply ignores all this competition for horsepower and remain happy to stay well below Kawasaki or Sea-Doo’s numbers. You might imagine this 250HP engine can’t match Sea-Doo’s or Kawasaki’s top PWCs.Jet skis can produce an average of 100-150 HP, within the 1,000-1,800 cc non-supercharged engines. The Rec-Lite category offers the lowest horsepower ratings of around 60-100 HP, while the Performance jet skis are powered with 230-310 HP supercharged engines. We recommend always doing your research prior to selecting a PWC and trailer. If you would like to review stats about various personal watercraft models from top brands, check out our Sea-Doo vs WaveRunner vs Jet Ski comparison tool! The Kawasaki ULTRA 310 jet skis offer the most horsepower on the market right now, as these jet skis are powered with 1,498cc, four-stroke, supercharged 310 HP engines. You can discover and compare these jet skis here.Stock jet skis have 60-310 HP engines depending on the make and the model. The non-supercharged (naturally aspirated) jet skis typically produce 60 -180 HP, while the supercharged models offer 230-310 HP. Sounds, simple enough, right? Imagine a machine with the strength of 2-horsepower on the same treadmill. It is able to power the same generator with double the effectiveness or 1,492 watts. These ponies are able to perform at about .7 horsepower rather than .5, thus making Watt’s calculations incorrect – hence why we think of it a bit differently today.The best power-to-weight ratios can be found in modified racing watercraft and have a stunning ratio of 1. For some racing examples, see Kevin Shaw’s article on power-to-weight ratios here.
In order to keep waterways safe, the US Coast Guard put in place a regulation limiting watercraft users to speeds of no more than 65 mph. Prior to 1999, there were no such rules in place and jet ski accidents were much more commonplace.
In the word of PWC enthusiasts, as in any area of motorsport, there are several numbers to keep in mind when choosing the right machine for you, including top speed and acceleration, gas consumption, purchase prices, and maintenance costs.
Though it may not be as flashy as horsepower, your personal watercraft’s power-to-weight ratio is actually what determines a great deal of its performance.
A lower weight leads to better acceleration and a more nimble hull – hence it leads to a machine that’s great fun to ride. Before you start having flashbacks to high school physics class, let us assure you that understanding this ratio is quite simple.
The Japanese manufacturer’s 4-cylinder, 4-stroke, supercharged 1,812 ccm SVHO engine has a hidden benefit: it’s highly receptive to modification. According to Kevin Shaw:Next on our list are 3 seaters like the Kawasaki Ultra Series, Sea-Doo’s top performance models, Yamaha FX series, and Yamaha GP1800R, all of which reach a 0.3-0.35 ratio, with 250-310 HP and 800-900 pounds net weight.
Now imagine the same machine with 200 hp and a weight of 400 pounds. Since we now have a machine with double the weight to power. Hence, the power-to-weight ratio is now 200/400, i.e. 1:2 or 0.5. This machine has the same power as the first but is twice as heavy.
Since the 1980s, manufacturers have been regularly increasing the horsepower of their machines year by year to serve the needs of the market and to annihilate the competition.The original calculation was based on the strength of Savery’s mine ponies, of the Shetland breed, and then doubled. Watt calculated that a horse had twice the power as the ponies.
Is a jet engine like a turbocharger?
Turbochargers as used on cars bear some similarities with jet engines. Fundamentally, both contain a turbine that harvests energy from hot gas, using it to spin a compressor which sucks in fresh air for combustion.
When it comes to personal watercraft, a great deal of attention is put on the performance specs. Just about every PWC enthusiast wants to check the current Yamaha Waverunner, Sea-Doo, and Jet Ski horsepower chart.
How much HP is a jet ski?
60-310 HP How much horsepower does a jet ski have? Stock jet skis have 60-310 HP engines depending on the make and the model. The non-supercharged (naturally aspirated) jet skis typically produce 60 -180 HP, while the supercharged models offer 230-310 HP.
“This though, has not dissuaded performance enthusiasts, as the SVHO has earned its keep as one of the most reliable and warmly receptive engines to aftermarket modifications. Tuners have pushed the engine’s boundaries to exceed 600-horsepower through ingenious means, including turbocharging, multiple-stage nitrous systems and even high-compression E85.”When it comes to power-to-weight ratios, Krash Watercrafts are the best of the best with some PWCs at 0.4-0.5 ratios and a 997 ccm two-stroke engine. These lightweight offerings are an excellent choice for more athletic PWC enthusiasts since they are mainly ridden in a standing position.
Can a jet ski last 1000 hours?
You can find jet skis with a lot of engine hours in good shape, while others are already dead after 100 or even just 50 hours! As evidence, you can find jet skis in rental shops with 1000+ hours in their engines, so this is a clue that with proper maintenance, a jet ski can run much longer than we would expect!
The Jet Ski horsepower numbers can range from 160 to 310 HP depending on the model. Sea-Doo offers PWCs from as low as 60 to as high as 300 HP, while you can find Waverunners with 73 – 250 HP engines.The original definition is exactly what you would imagine it means: the power exerted by a horse when it is pulling something. It does, however, also carry a very specific meaning, which is the most useful definition for us today.
When searching for the right personal watercraft, consider how important watercraft performance is to you. For those of you interested in PWC racing, perhaps a Yamaha with SVHO engine is a perfect choice. Regardless of the error, Watt’s term and the concept behind it have made it down through the centuries to appear today on the stats for your car or PWC. To formulate this unit, he looked to a book written by English inventor Thomas Savery in which he compared the work of cart-pulling mine ponies to an imagined machine which could consistently do the work of 10-20 of these ponies at a time.He found that, on average, a Shetland could perform at about 22,000 foot-pounds of work per minute. If a full-size horse was able to operate at 50% above that power, she could reach 33,000 foot-pounds per minute.
Surprisingly, one of the possible answers was in the weight of the watercraft. Because PWCs have grown bigger and bigger over the years, many performance models are now considered boats by many customers!
Let’s consider a simple example of a horsepower calculation using the US measure. As you are already aware, 1 horsepower unit is equivalent to 745.7 watts in the United States.
Not only this but since the late 1980s, manufacturers were in a race to see who could create a machine with the greatest horsepower. Unsurprisingly, this led to some very dangerous waters.
For those who prefer Yamaha, check out their FX SVHO or GP1800R Waverunners. With an acceleration rate of 1.5 seconds for 0-30 mph, they prove quite impressive.With 54 models on the market from the four manufacturers alone (Yamaha, Kawasaki, Sea-Doo, and Krash Industries), it’s a challenge to compare all of these machines by performance data and other specs.Whether you are simply curious about the offerings on the market, or you are a hard-core PWC enthusiast, there is one question we are certain is on your mind:
As you’ve likely figured out by now, the fastest Jet Ski, Waverunner, and Sea-Doo models have the potential to go much faster than 65 – 67 mph, though they can’t do so straight off the shelf.Fastest Waverunners from Yamaha: The fastest Waverunner models are the Yamaha GP1800R, and the FX series. These watercrafts come with a supercharged 1,812 ccm, 4-cylinder, 4-stroke, SVHO engine with around 250 HP and top out at around 67 mph.These units are available at the well-known watercraft aftermarket performance specialists like RIVA Racing or PWC Muscle. Using this modification alone, you could reach up to 75 mph.
What is the fastest a jet ski has ever gone?
The World’s fastest Jet Ski, Sea-Doo and Waverunner The record for the top speed ever reached on a watercraft belongs to Uva Perez, who recently hit a whopping 127 mph on a modified Yamaha Waverunner.
As you can see in the compilation chart above, there are several models that can easily reach the 65 mph, or even 67-70 mph depending on the weather conditions.
Though it’s not recommended that casual PWC users modify their watercraft in this way, it is possible. If you really want to do it, you simply need to find a service shop that will assist you. If you would like to discover more about these amazing models, click on the link in each model’s name. You can find pictures, videos, additional specs and head-to-head comparisons. It’s important to remember, however, that the Coast Guard’s speed limits are in place for your safety. And don’t forget the essential safety gear, especially at the speed of 111 mph!
The fastest jet skis can go around 67 mph in the US, as their engines are electronically limited. Overriding the speed limiter unit (or riding an international model) you can expect around 75 mph on the fastest jet skis. But with additional modifications, you can reach 80-90 mph!
The fastest stock Sea-Doos in 2023 are the RXP-300 and RXT-X 300, and the GTX series. As these are the fastest Sea-Doos on the market, they all arrive with the same 1630cc supercharged engine, which produces 230-300 HP, depending on the model. You can expect 67 mph top speed on these models.It goes without saying that calm waters are preferable to rough when you want to maximize speed. Choppy water may not be the only condition that will slow you down, but it’s definitely a factor, so test out on smooth.
Due to the artificial limits, it’s extremely challenging to compare the performance of models from different manufacturers. Tests done can often be unconvincing because all models are set to reach 65 mph only.The last thing to keep in mind is the water you are in. Salt and freshwater may present different results. In case you’re curious, the USCG tests are done in saltwater.
A few tips: If you would like to sort the rows, click on the header. To find out more information about a particular model, click on the name. Doing so will lead you to additional specs, pictures, videos, and head-to-head comparisons. Don’t hesitate to discover more!
The fastest jet skis on the market are definitely the Performance and Luxury models, as they’re powered with 1,500-1,800cc supercharged engines. These power plants offer amazing 230-310 HP depending on the model, and can reach the top speed of 67 mph!
The average jet ski can go as fast as 50-55 mph, which is amazing speed on the water, but many beginners consider it too fast! It’s because unlike in your car, on a jet ski there’s no wind protection, so you’re much more exposed to the elements. What’s more, you sit close to the water which makes the ride more thrilling!
We all know that faster acceleration means more fun adn better riding experience. A watercraft that’s more fun is going to get more attention – and more buyers.A 700cc jet ski can go as fast as 40-45 mph depending on the model. These models are usually vintage 2-stroke jet skis, as the newest models arrive with 900-1,800cc 4-stroke engines.
For this reason, many manufacturers are now focusing their efforts on developing other areas that affect performance like the acceleration, power-to-weight ratios, and weights.
Fastest Jet Ski Models from Kawasaki: The most powerful models from Kawasaki are the Ultra 310 series: Ultra 310X, Ultra 310R, Ultra 310LX, Ultra 310X SE. These PWCs boast 310 HP with a 1,498 ccm, supercharged 4-stroke and 4-cylinder engine. You can easily reach 67 mph on these bad boys.60 HP jet skis can go as fast as 42 mph. Even if it’s significantly less than the supercharged model’s top speed, it has to be mentioned that 42 mph is an amazing speed on the water, especially on a small and lightweight jet ski!
If you are looking for the the world’s fastest Jet Ski, Waverunner and Sea-Doo, then this post if for you! We provide here detailed information and videos on these PWCs.
300 HP jet skis can go as fast as 67 mph, but without the speed controller unit, they can hit 75 mph, or even faster! What’s more, beyond the amazing top speed, you can expect thrilling accelerations with these jet skis, as their engines are boosted with superchargers.
No, there is no speed limit for jet skis. Instead, there is an agreement between the U.S. Coast Guard and the PWC manufacturers. According to this agreement, every new high-performance jet ski arrives with a speed controller unit, which limits the jet ski’s top speed electronically. So ultimately, there is no official speed limit for jet skis, as even the newest performance models can’t go faster than 67 mph.Yes, most powerful supercharged jet skis can go 80 mph, but not in stock condition! To reach this speed, they need some modifications like installing a speed control override unit, or installing other aftermarket performance parts.The US Coast Guard tests are made in salt water with a 200-pound rider and a full tank of fuel. The highest performance models have 16-21 gallons fuel capacity, which translates to 100-130 pounds of additional weight.The fastest stock jet skis from Kawasaki are arguably the ULTRA 310 series, powered with 310 HP supercharged engines. So this is the fastest jet ski on the market in 2023 with the top speed of 67 mph.
It’s safe to say that 45 mph isn’t fast for a jet ski nowadays. It’s because unlike the small and lightweight vintage 2-stroke jet skis, the newer models arrive with much bigger hulls that result in higher stability even at higher speeds.If you wish to compete in racing, you are certainly welcome to modify your machine but don’t forget to always ride safely and with caution. Follow the rules every time you’re out on the water.
Unfortunately for those in the market for a PWC, manufacturers don’t provide these specifications as official data. We have to rely on other sources like journalists and industry experts such as those we mentioned in the introduction to this post.
Each of these models may even be able to reach 67-70 mph in good weather if you have a light fuel and gear load. Due to speed limiters, however, you won’t top this without modifications.Another important factor is temperature. A hot sunny day can sap your energy’s power. Even high altitude or the pump’s nozzle trim position can slow you down! If you are interested in the world’s fastest Sea-Doo, it is owned by Carlito del Valle. He first broke the (IJSBA-certified) world record in 2016 with a speed of 113.7 mph. The fastest stock WaveRunners in 2023 are the legendary GP1800R HO and SVHO, as well as the FX series. These are the fastest WaveRunners in Yamaha’s fleet, as all of them can hit 67 mph. Their power source is an 1812cc, four-stroke engine offering 250 HP.As you’ve likely figured out by now, the fastest Jet Ski, WaveRunner, and Sea-Doo models have the potential to go much faster than 65 -67 mph, though they can’t do so straight off the shelf.
Do jet skis have turbos?
4-Stroke Supercharged Jet Ski Engines It does the same job as a turbo on cars, but unlike turbos driven by exhaust gases, jet ski superchargers are connected to the crankshaft by a set of gears.
Would you like to read more about these performance specs like horsepower and power to weight ratio in general? If yes, please check out our article on this important topic.
Yet the joy of a ride doesn’t just come down to speed. Acceleration plays a key factor when it comes to your PWC’s level of fun. With some models that can reach 0-30 mph in under 2 seconds, you are sure to have a great time even at the Coast Guard’s speed limit.Fastest Sea-Doo models: The top speed Sea-Doo models are the GTR-X 230, GTX Limited 230, RXP-X 300, RXT-300, GTX Limited 300 which arrive supercharged, 1630 ccm, 4-stroke Rotax (closed loop cooling) engines and 230-300 HP performance. Today’s jet skis can go as fast as 40-67 mph on the water depending on their engines’ performance, for which this range typically requires 60-310 HP. In contrast, the first 2-stroke jet skis could barely go faster than 25-30 mph, as they were powered with low-performance air-cooled engines! Manufacturers were required to install speed limiter units into the models which would limit the power of the engine. Hence, tops speeds were artificially capped.High winds are, of course, not ideal for testing top speeds. It’s best to test in wind-free moments. If this is not possible, try your watercraft out downwind.
Is 100 hours a lot on a jet ski?
A Jet Ski or a Sea-Doo are brand names of PWC, and the average person puts around 30 hours a year on their machine. A low-hour ski is a machine that has been used for less than 50 hours, while 150 hours or more of use is considered high.
The acceleration tests performed by these sources measure the amount of time it takes for a given model to reach either 30 mph or 60 mph from a stand-still.
How fast does a 180 hp jet ski go?
How fast is the 2023 Yamaha GP1800R HO? The former Yamaha VXR, the 2023 Yamaha GP1800R HO top speed is 67 mph. This WaveRunner is manufactured with a non-supercharged, 1812cc, 4-stroke, 3-cylinder engine producing 180 HP.
When you’re hoping to reach top speeds on your PWC, we recommend paying attention to conditions. Your maximum speed is dependent on many factors, all the way from the temperature outside to fuel weight.If you wish to test out speed and acceleration for models from the major brands for yourself, please check out our watercraft rental locator and infographic guide here.
Riding on full throttle can be quite dangerous, so please ensure the waterway is clear, you are in a regulated area, and conditions are safe before testing out your machine at 65 mph or more.
Air conditions also affect the speed of your ride. Low humidity rather than high is likely to get your PWC moving quicker. High humidity or air pressure forces engine to work harder, thus slowing them down. Most powerful and fastest Waverunner models are known for their capacity to be modified to reach incredible speeds, and Perez’s model was certainly no exception! The 10 year age span is a kind of boundary for many buyers, which means it may be harder to sell beyond that range. This is because many jet ski service shops also refuse to work with jet skis over 10 years old!Their main advantage is that these jet skis are really agile and fun to ride, offering a vastly different riding experience compared to the current, larger watercrafts, which are considered “couches” by many jet ski riders.
If you’re planning to buy a used jet ski, the best practice is not to buy a model that is older than 6-7 years old and has a maximum of 150-200 hours on it. The best practice is to focus on the younger models with 50-70 hours to find the best deals for the long run.
Generally speaking, if a jet ski is used less than 30 hours per year, it’s usually categorized as a “low-hour jet ski” while more usage is a “high-hour jet ski”.
These motors are extremely powerful, typically producing 230-310 HP depending on the model. While they offer amazing performance on the water, you can expect much more maintenance, higher fuel consumption, higher risk of malfunctioning and shorter lifespan.
Unlike rentals, an average owner uses around 30 hours on their jet ski in a year, so it means a you can find a typical 5 year old jet skis with 150 hours, while the 10 year old skis usually have 300 hours on them. These numbers can vary widely of course, depending on the owners, but as a rule of thumb, you can count on 30 hours yearly.
As evidence, you can find jet skis in rental shops with 1000+ hours in their engines, so this is a clue that with proper maintenance, a jet ski can run much longer than we would expect!
If you can find a jet ski with only 50-70 hours, these models could be the best deal for you in the long run. Additionally, keep in mind that the low hours will mean a higher selling price as well.Another reason is that rental companies are always extremely picky about choosing the most reliable jet ski models on the market, and with good reason. Constant breakdowns always mean a huge hassle for staff, which can finally lead to dissatisfied customers, less income and a declining reputation!
As a rule of thumb, an average jet ski is used around 30 hours every year, but this number can vary widely depending on the owners. It’s not uncommon to see a 10 year old jet ski with less than 100 engine hours, while other owners ride 100 hours every year!
Additionally, when you select your ski, you shouldn’t have to focus exclusively on the jet ski’s engine hours. As you’ll see, the maintenance history is more important than the hours on the jet ski!In any motorized vehicle, higher performance means higher chance of malfunctioning and a shorter lifespan. Interesting fact: Formula 1 engines are rebuilt after nearly every race, while a simple engine in a Toyota Camry lasts forever.
But again, the condition of the jet ski is more important than the engine hours. If you would like to learn what to check on a used jet ski before buy, don’t miss our step-by-step used jet ski buyer’s guide.
In freezing weather, expanding ice can damage the cooling system, intercooler or exhaust system. Missed oil changes are bad for the engine, and lack of lubrication on the moving parts can lead to rust, and the list is pretty endless! So even if an aged jet ski’s engine is running, the need to replace an expensive part may mean the end of the jet ski’s life, as it’s no longer worth repairing. That’s why rental companies avoid high-performance, supercharged jet skis. As we’ve mentioned above, the supercharger consumes a lot of maintenance hours, and makes the jet ski less reliable. Additionally, these models have the highest price tags and maintenance costs as well!
In case you can’t find the engine hours, you can take the jet ski to a service shop or dealership where professionals can help you with this issue. It’s always wise to take a used jet ski to a dealership for an inspection before you buy, so you can ask them to check the engine hours on the computer at the same time.
The reason for this is that the manufacturers want to keep the craft’s weight low and increase their power-to-weight ratio. In this way, they can produce faster, lighter and more agile jet skis.It’s an essential inspection so never miss it! Some dishonest owners install new gauges to reset the jet ski’s engine hours, to try to scam you in this way. But don’t worry, fortunately, the newest models save the engine hours on more places in the ski than just in the gauge.
In general, 300 engine hours on a 4-stroke jet ski is already considered high usage hours, so it’s always wise to purchase a model with less usage. Based on experience and best practices, you shouldn’t buy a used jet ski which is more than 6-7 years old, and has 150-200 engine hours on it. And you can imagine how much abuse these jet skis get day after day from inexperienced or wreckless customers. So the high usage hours on these rental models mean really hard use! In the past, 2-stroke jet skis were more common, but today, most of the jet skis arrive with 4-stroke engines. However, you can still find 2-stroke stand-up jet skis on the market. You may ask: How many hours will a 2-stroke jet ski last?The attitude and care of the owner can directly affect the lifespan of a jet ski. If the owner’s manual and basic rules of operation are overlooked, the jet ski may be in worse condition than originally thought. Here are some examples of how owners can abuse their jet skis: Their engines are worn out, and create more pollution compared to a new jet ski (or even banned in certain areas!). The other issue we’ve mentioned is that many service shops may refuse to work with jet skis older than 10 years. To sum it all up, the main takeaways are that when it comes to purchasing a used jet ski, the condition and maintenance of the machine is always more important than the engine hours. You can find jet skis with a lot of engine hours in good shape, while others are already dead after 100 or even just 50 hours!
Can you make a jet ski faster?
This complete guide will teach you how to make your jet ski faster and even more awesome!Start With a Reliable Jet Ski. … Take Upgrades Into Account. … Install a Fuel Tuner. … Replace the Intake Grate. … Swap the Impeller. … Remodel the Air Intake. … Upgrade the Exhaust System. … Modify the Engine.
Many rental companies change their fleet frequently, and these rental jet skis appear on the second-hand market year after year. You may be wondering if you should buy one? It’s not recommended!
When it comes to 2- stroke jet ski engines, the rule of thumb is that 200 hours are considered high engine hours. Because of this, if you’re looking for a 2 stroke, try to choose a second-hand model with around 100 hours on it, but the less the better. As always, the overall condition is more important than the engine hours!
Every owner’s manual strictly outlines required service intervals. Beyond regular service, jet skis need to be winterized in most cases. Additionally, every owner should carefully check their skis before and after rides!One of the reasons for this is that these fleets are inspected regularly, and maintained on a really high-quality and professional level. That’s one of the main reasons why these jet skis last so long!Beyond the engine hours, the age of a jet ski is also important. The engine hours are obviously a deciding factor in your purchase as well as the year of the model. Usually, the older the jet ski, the more hours it has on the water.As we’ve mentioned, beyond the high engine hours, these machines get a lot of abuse from customers, so we can’t recommend buying a used rental jet ski.
What is the fastest jet ski engine?
The Supermarine MM01 is a must-have for high speed water enthusiasts, as it boasts incredible performance. Its full electric motor puts out 300 HP (220 kW) of energy with 450 Nm of torque – enough to reach speeds up to 75 mph (121 km/h).
This is because after you purchase your ski, over the next 2-3 years, you’ll probably put another 30 (or even more) hours on it, annually. This means after a couple of years, your craft will be around 10 years old and will have around 250-300 hours on it. That will mean noticeable wear which indicates it’s likely time to upgrade your craft.When it comes to the average lifespan of a jet ski, it’s hard to state a hard number because it depends on many factors like the model, performance, maintenance and the owner’s care and attitude. But as a rule of thumb, it’s not recommended you buy anything that is older than 6-7 years old.
How fast can a 300 hp jet ski go?
67 mph When it comes to the Sea-Doo RXT-X 300, you can expect 67 mph top speeds and extreme acceleration. This model is powered with a 1630cc, 4-stroke, 3-cylinder, supercharged Rotax engine, which offers not less than 300 HP.
When you do your research on this topic, you can find a lot of confusing info about how long a jet ski engine lasts, so it’s not clear what the real lifespan of a jet ski is and which one is worth buying.
To help your purchasing decision, we at JetDrift have compiled the most important facts about a jet ski engine’s lifespan, as well as some other import factors you need to keep in mind before purchasing a used jet ski!However, it’s good to know that 4-stroke stand up jet skis are also available on the market since 2015. Namely, this model is the Kawasaki SX-R 1500, so don’t hesitate to discover this model here!
When it comes to the lifespan of jet skis, it usually not only depends on engine hours, but several other factors as well. Let’s check them one by one:
These features include brake and reverse systems, large touch screens, and many other electronic stuff. Although these new inventions are super cool, keep in mind that they may not work well after 5, 10, or 15 years.Instead of, we highly recommend you buy a newer 4-stroke sit-down jet ski model. If you’re looking for something small, you should take a look at the Rec-Lite category!The weight of a 2-stroke engine is always much lower, so using these engines makes sense for stand-up jet skis. Additionally, all of the vintage stand ups, and the majority of the current stand up models come with 2-stroke engines.
As a rule of thumb, the 2-stroke jet ski engines last around 200-300 hours, while the 4-stroke jet ski engines last around 300-500 hours. But keep in mind that these numbers depend on factors like maintenance, usage, and many others!
Every newer sit-down jet ski has a gauge or screen, and when the key is attached to the ski, you can check the engine hours on it. Some models show the number of hours by default, while on some models you have to press a “mode” button to find it. It’s true especially in case of the lower-end models on which screen is typically smaller.
If we’re talking about the lifespan of a jet ski, we shouldn’t be limited to the engine. Just like with cars, today’s jet skis are much more complex and are equipped with many extra bells and whistles.
All 2-stroke sit-down jet skis on the market are pretty old. The purchase price of these vintage models may attract you, but they’ll come with much more hassle (and sometimes costs) compared to many newer models.
In general, every 4-stroke jet ski over 300 hours is considered a lot of usage, while in the case of 2-stroke jet skis, this number is around 200. But proper maintenance is always more important than engine hours!As you can see, there are many factors to consider, but the engine hours still matter, of course. So you may ask: Is 200 hours a lot for a jet ski? Is it still worth buying?
Beyond this advice, it’s highly recommended you get a prepurchase inspection from a dealership or service shop before buying a jet ski. Also, don’t miss the water test!If you choose your jet ski carefully, pay attention to operating it properly and give it regular maintenance, you can expect a longer lifespan. On the other hand, you can destroy your engine easily in a very short amount of time!
