Yamaha FX Limited SVHO vs. Kawasaki Ultra 310LX

By the Numbers

Although both the FX Limited SVHO and the Ultra 310LX are classed as touring jet skis with a luxury accent, there are many differences between them. The latter is known for its innovative features and extreme power, while the Yamaha has built a reputation for reliability and durability.

Regarding dimensions, the Kawasaki measures 140.9 inches in length, 47 inches in width, and 48.8 inches in height.

This new Kawasaki Ultra hull debuted for the 2022 model year as an all-new touring platform for the flagship models. Compared to its predecessor, this shell is larger, much more stable, and features a revolutionary top deck design.

The rival Yamaha FX Limited SVHO is built on the largest and most stable FX WaveRunner hull, measuring 140.9 inches in length and 50 inches in width.

What’s more, the dry weight of the FX is only 877 pounds, which translates to a curb weight of 1003 pounds. In contrast, the Kawasaki weighs 950 pounds dry, and 1090 pounds fully loaded.

The latter comes with much greater capacities as well since it has an industry-leading 21.1-gallon gas tank and a storage capacity of 44.5 gallons.

These storage areas include a 32.8-gallon standard bow storage, a small rear wet storage, and two unique gullwing gloveboxes on both sides of the deck. These units offer 10.6 gallons of storage space and are equipped with a dry box for smartphones.The storage capacity of the Yamaha is exactly the same (44.5 gallons) split into a standard glovebox, bow storage, and a small storage box under the rear portion of the seat. Its fuel capacity is 18.5 gallons.

As the name suggests, the FX Limited SVHO comes with a supercharged, 4-stroke, 1812cc, fuel-injected, 4-cylinder SVHO Yamaha marine engine rated at 250 HP.

You can expect more power on the Kawasaki since it houses a supercharged, 1492 cc, fuel-injected, 4-cylinder Kawasaki engine rated at 310 HP. This power mill is borrowed from Kawasaki’s ZX-R Ninja motorcycle family.

Both engines are paired with a standard axial-flow, single-stage PWC jet pump.

Performance and Handling

Both the FX Limited SVHO and the Ultra 310LX are built on a stable and predictable touring hull.

Unlike their race-intended counterparts, these large massive platforms ensure dry comfortable rides even on choppy waters. On the other hand, they are much less nimble and responsive, which translates to a less playful riding experience.

In terms of performance numbers, both skis can accelerate from 5 to 60 mph in about 4.5-5 seconds under ideal conditions. Top speed is electronically limited to 67 mph, but with a light load they can even hit 68-70 mph on good days.
