Sea-Doo Spark Evo Jet Kart Review
Although this amazing vessel is marketed under the name of Sea-Doo Spark Evo Jet, but it’s often called a Sea-Doo Spark Jet Kart, Spark Evo Jet Kart, or just the go-kart of the seas.
All of these names refer to the same modified Sea-Doo Spark PWC, designed and built by American Jet Concept.
Thanks to these modifications, the Sea-Doo Spark Evo Jet doesn’t feature a traditional jet ski saddle. Instead, it comes with an aftermarket bucket seat, which allows you to sit inside the hull!
The handlebar is also replaced with a race-inspired steering wheel, which means you can drive the Spark Evo Jet like a go-kart rather than a regular jet ski.
The low center of gravity also results in outstanding stability, making the machine difficult to flip over.
Let’s get down to the nitty-gritty and take a closer look at the details!
Sea-Doo Spark Evo Jet Kart Conversion Kit
If you want to get a Sea-Doo Spark Evo Jet, you literally have three different options.
- Converting your Sea-Doo Spark into the Evo Jet by installing the conversion kit (if you already own a Spark)
- Purchasing a Sea-doo Spark and the kit separately to build your own Spark Evo Jet
- Investing in a “ready-to-go” Spark Evo Jet manufactured by American Jet Concept

“Ready-to-Go” Spark Evo Jets
If you prefer ready-made solutions, the good news is that besides the kit, the manufacturer also offers complete Spark Evo Jet Karts for sale.
Simply put, these machines are stock Sea-Doo Spark models manufactured by BPR that have been converted into Jet Karts by American Jet Concept.
If you invest in a factory-made Evo Jet Kart, you get a water-ready Spark Evo Jet Kart along with the jet ski’s original seat, deck, and other parts.

- Spark Evo GT 60 HP 2UP

Are you curious about the performance of the Spark Evo Jet Kart? Let’s drill into the details!
Sea-Doo Spark Evo Jet Kart Specs
Evo Jet Kart Top Speed
As a rule of thumb, a Sea-Doo Spark Evo Jet Kart can go as fast as 42-53 mph. The 90 HP models can reach a remarkable top speed of 48 mph, while you can expect 42 mph on the 60 HP Evo Jet Kart. If you are looking for more power, you can even consider installing a 120 HP performance kit. With this aftermarket modification, the Spark Evo Jet can reach a top speed of 53 mph.
Although this performance kit adds a lot of extra power to the machine, keep in mind that this modification may void the warranty.
To the delight of performance-minded riders, there are rumors that a turbocharged Spark Evo Jet Kart is on the way!
According to the manufacturer, the Spark Evo Jet Turbo will put out 170 HP and offer an amazing top speed of 65 mph.
Spark Evo Jet Kart Dimensions
Regarding Spark Evo Jet Kart dimensions, the hull of the original Spark is left basically unchanged. This means stock Sea-Doo Spark models and Evo Jet Karts share the same sizes; they are 110-120 inches long and 46.4 inches wide.
The Evo Jet Kart 2UP models are more agile and maneuverable thanks to their shorter (110”) hull. If you are looking for more stability, take a look at the 3UP Evo Jets, as they feature a 10-inch extension platform, which makes these hulls more stable, especially at higher speeds.
Sea-Doo Spark Evo Jet Cart Prices
You can find the prices of Sea-Doo Spark Evo Jet Karts in the ballpark of $14,990 – $17,990. Don’t forget that for this price you get a water-ready Spark Evo Jet Kart along with the original features of the Spark! So, finally, you can find the Spark’s top deck, seat, handlebar, and fuel tank in the package beside the Evo Jet.
Without the installation, the price of a single Spark Evo Jet Conversion Kit is only $8,490, but be prepared to pay $1,090 for the 120 HP performance package.
