If you would like to learn more about this unique vessel, this post is for you.

We at JetDrift have done the research and collected all the info you need into this Sea-Doo Spark Evo Jet review!

Sea-Doo Spark Evo Jet Kart Review

Although the official name of these machines is Sea-Doo Spark Evo Jet, they are known by many different names, such as Sea-Doo Spark Evo Jet Kart, Sea-Doo Spark Jet Kart, or simply Sea-Doo Spark Evojet.

All of these terms refer to the same unique PWC, invented and manufactured by American Jet Concept.

But what makes this product so outstanding in the market? If you take a look at this mini race boat, the answer is clear: you can sit inside of the hull instead of on top of it!

This is possible because the top deck of these Sea-Doo Sparks was completely redesigned. It features a racing seat and a custom steering wheel instead of the regular handlebar.

This means you can drive this machine like a go-kart!

Thanks to the low center of gravity, the hull is much more stable than the regular design. This makes the Sea-Doo Jet Kart virtually unflappable on calm waters. (Or, at least, extremely hard to flip.) But even if it does accidentally flip, the driver can easily escape the hull like from a kayak.

Another great advantage of the design is that it can also be driven by people who are paralyzed.

Let’s drill into the details and take a closer look at this unique product!

The Sea-Doo Spark Evo Jet Kart Conversion Kit

To turn a Sea-Doo Spark into this mini race boat, you need a kit, called a Sea-Doo Spark Evo Jet Kart Conversion Kit.

If you already own a Sea-Doo Spark, the good news is that you can purchase this conversion kit separately. Since the kit is “ready to plug,” you can simply bolt it on in about three hours.

The biggest advantage of this conversion is that it’s completely reversible. This means if you want to use your Spark as a regular PWC, you can simply replace the original deck and seat!

This is also a great point if you want to sell the craft, since the kit and the PWC can be sold separately.

The Spark Evo Jet Kart conversion kit consists the following components:

  • Full top deck with nose and rear cover
  • Footrest
  • Steering wheel with steering cable
  • Trigger
  • Bucket seat and brackets
  • Roll cage
  • 11-gallon aluminum gas tank
  • Bracket intake airbox and battery
  • Wire harness for the cluster
  • Sponsons
  • All fasteners
  • Installation instruction manual

Factory-Built Evo Jets

For those who do not yet own a Spark the manufacturer offers complete Sea-Doo Evo Jet Karts for sale. These machines come with a factory-installed conversion kit, but the original top deck and features are also shipped with the product.

If you are looking for a Sea-Doo Spark Jet Kart off the shelf, you can currently choose from these 5 different models:

  • Spark Evo GT 60 HP 2 up
  • Spark Evo GT 90 HP 2 up
  • Spark Evo GT 90 HP 3 up
  • Spark Evo GT 90 HP 2 up iBR
  • Spark Evo GT 90 HP 3 up iBR

Sea-Doo Spark Evo Jet Kart Top Speed

The top speed of the Sea-Doo Spark Evo Jet Kart is about 42-53 mph depending on the model. With the 60 HP engine you can expect about 42 mph, while the 90 HP models can hit 48 mph under ideal conditions. The manufacturer also offers a 120 HP performance kit for their crafts, which can increase the top speed of the Sea-Doo Spark Evo Jet up to 53 mph.

What’s more, according to American Jet Concept, they are working on a Spark Evo Jet Turbo model.

The expected horsepower of this turbocharged Evo Jet is no less than 170 HP with a top speed of 65 mph.

Since the weight of this machine is only 420 pounds, it promises an outstanding power-to-weight ratio!

The components of the 120 HP performance kit are as follows:

  • Reflash ECU at 120 HP (specially developed for the Spark Evo Jet)
  • Ribbon delete
  • Free flow exhaust (WORX performances)
  • Aftermarket impeller (Solas Concord 12/14)
  • Installation

These tunes can make your Spark Evo much faster, agile and aggressive. On the other hand, don’t forget that the installation of this kit may void the warranty of the Spark!

Sea-Doo Spark Evo Dimensions

When it comes to the dimensions of the Spark Evo Jet, it’s good to know that the hull of these PWCs have remained unchanged. This means the dimensions of the Spark Evo Jet Karts are exactly the same as stock Sea-Doo Spark models, which are 46.4 inches wide and 110-120 inches long.

The “2 up” models come with a 110-inch-long hull, which makes these models extremely nimble and maneuverable. In contrast, the “3 up” Evo Jets are slightly longer since their hull got a 10-inch rear extension.

Thanks to the longer hull, this model is more stable especially at higher speeds.

One of the cons of the Sea-Doo Jet Karts is that they can accommodate only one rider. So, if you want to ride with passengers, you have to convert the machine back to a regular PWC.

If you do that, the “2 up” models can carry 2 riders, while the “3 up” Sparks offer seats for 3 passengers.

How Much is a Sea-Doo Spark Evo Jet Cart?

The prices of Sea-Doo Spark Evo Jet Carts start from $14,990 (60 HP) and go up to $17,990 (120 HP). These prices include the stock Sea-Doo Spark and the conversion kit as well. The machines are delivered with the kit installed, but the Spark’s original top deck, seat, handlebar, and fuel tank are also included in the package.

If you are looking for just a Spark Evo Jet Conversion Kit, be prepared to pay $8,490, which doesn’t include the installation. The 120 HP performance kit is available as an option for an additional $1,090.

So in summary, the prices of the different Jet Kart models are as follows:

  • Evo Jet Spark 60 HP: $14,990
  • Evo Jet Spark 90 HP: $15,990
  • Evo Jet Spark 120 HP: $17,990
