Yamaha EX Review
Yamaha released the EX family in 2017 to compete with the widely popular Sea-Doo Spark series. All of these machines are categorized in the Rec-Lite class.
The 2022 Yamaha Rec-Lite WaveRunner line consists of four different models, including:
- Yamaha EX – MSRP: $7,199
- Yamaha EX Sport – MSRP: $8,299
- Yamaha EX Deluxe – MSRP: $9,299
- Yamaha EX Limited – MSRP: $9,899
(You can discover these models by following the links above.)
The most basic and affordable model in this breed is the Yamaha EX. Let’s drill into the details and take a closer look at this ski!
Dimensions and Capacities
Compared to its full-sized brothers, the entire EX family is built on a much smaller platform.
The hull of the Yamaha EX is 123.2 inches long, 44.5 inches wide, and 45.3 inches high. The dry weight of this ski is only 578 pounds, which translates to an approximate curb weight of 670 pounds.
Thanks to this lightweight body, the EX is easy to handle, and can even be towed by a small car.
Regarding capacities, the total storage capacity of the Yamaha EX is 7.7 gallons, which splits into a wet bow storage, a roomy glove box, and a small under-seat storage.
The ski also houses a 13.2-gallon fuel tank that provides more than 4 hours of playtime at best cruise speed. However, if you ride hard, you can dry its tank out in only 1.7-2 hours!
Yamaha EX Engine and Propulsion
The engine of the 2022 Yamaha EX is the reliable Yamaha TR-1 Marine Engine. This lively 1049cc, 4-stroke triple puts out 100 HP at 7,300 RPM.
The key features of the Yamaha EX engine are as follows:
- Displacement: 1049cc
- 3 cylinders
- Bore x stroke (mm): 82 × 66.2
- Electronic fuel injection system
- Total oil capacity: 3.91 US qrt.
- Open-loop cooling system
Power is delivered towards the 144mm axial flow jet pump through a direct drive shaft.
Yamaha EX Performance and Handling
Although this model is considered an entry-level Yamaha WaveRunner, it offers pretty good performance.
The top speed of the Yamaha EX is about 50-51 mph, and it can go from 0 to 30 mph in 2.3 seconds or 0 to 50 mph in 10.5 seconds. With some aftermarket modifications, you can increase its top speed to 55-58 mph.
This machine is definitely not the fastest jet ski in the marketplace, but don’t forget that 50 mpg is very fast on the water!
What’s more, thanks to its lightweight and agile hull, the EX offers very playful rides.
On the other hand, it’s good to know that even if the EX is marketed as a 3-seater jet ski, it can barely carry three adult riders. Instead, this model is mainly recommended for solo rides or for a maximum of two average-sized adults.
Although its weight capacity is 529 pounds, its hull becomes very tipsy and hard to maneuver with this load, especially at lower speeds.
Yamaha EX Features
The key features of the 2022 Yamaha EX are as follows:
- Multifunction information center
- Ski hook
- Deck mats
- Glove box
- Underseat storage
- Wet bow storage
The biggest drawback of the base Yamaha EX is that it comes without a reverse system. The lack of reverse makes maneuvering more difficult around docks, launching the craft, and riding in tight places.
The more advanced EX models come with higher price tags, but they are equipped with mechanical reverse and other bells and whistles.
