Yamaha VXR 650 Review

Yamaha VXR 650 Hull and Top Deck

Yamaha introduced its 2-stroke VXR series in 1991 as its flagship performance runabout PWC line. This series included the VXR 650, the base VXR, and its top-of-the-line VXR Pro 700.

Each of these skis was built on the same VXR platform, measuring 109.1 inches in length, 40.2 inches in width, and 35.5 inches in height.

Even though the measurements of the shell on these skis were completely identical to the WaveRunner III 650, it featured a different design that was optimized for performance.

(Due to their similar body and features, these models were often confused, but they featured a different hull design and drivetrain.)

The key advantage of the VXR hull was its concave shape, which was less prone to slipping out in the corners. Therefore, it offered sharper turns and a more aggressive riding experience.

Thanks to its outstanding characteristics and a more powerful engine configuration, VXRs became some of the best-selling Yamaha WaveRunners in the early ‘90s.

The first model in this breed was the VXR 650, which was revealed in 1991. As the name suggests, this ski was powered by the lively 650 marine engine.

Let’s get down to the nitty-gritty and talk about this power source in detail!

Yamaha VXR 650 Engine

The engine of the Yamaha VXR 650 was a 2-stroke, 633cc, twin-cylinder Yamaha marine engine that built its reputation on its legendary durability and reliability.

It came standard with a wide range of innovative features, including CDI ignition, electric start, a Mikuni carburetor, and an open-loop cooling system.

According to its operator’s manual, this Yamaha 633cc marine engine in the VXR 650 delivered 50hp (37.3 kW) at 6000 RPM.

Even though the same engine was used in many other WaveRunners like the III 650, and the stand-up SuperJet 650, these models were only rated at 42hp at 5500 RPM.

They also featured an outdated mixed-flow jet pump, which produced a thrust of 385 pounds.

In contrast, the more powerful engine of the VXR 650 was paired with a more advanced axial-flow jet pump, housing a 5-blade aluminum impeller. This propulsion system provided almost 30 percent more thrust; 496 pounds to be precise.

The maximum fuel consumption of the VXR 650 was 5.5 US gallons at WOT, so its 7.9-gallon fuel tank only offered 1.4 hours of riding time.

The top speed of the ski was roughly 35-40 mph depending on environmental conditions.

Yamaha VXR 650 Features

Unlike today’s luxury PWCs, the VXR 650 was only designed with a few basic features, which were as follows:

  • Seat storage compartment (capacity: 14.5 lb)
  • Water-resistant storage container (capacity: 2.09 lb)
  • Fire extinguisher container
  • Bow and stern eyes
  • Front
  • Engine stop switch with safety lanyard
  • Deck mats
  • Drain plugs
  • Rope holes
  • Grab handles
  • Fuel cock
  • Oil level gauge
Interestingly, the storage compartment of the ski was located under the seat.

This was no surprise since the engine was nestled forward in the hull, beneath the handlebar area. Because of this, the handlebar was mounted on top of the hood, which is quite a strange design from today’s perspective.

But back in the early ’90s, this “vintage snowmobile-like” platform design was standard in the PWC industry.

Yamaha VXR 650 Problems

Even though the VXR 650 was an extremely reliable 2-stroke WaveRunner, it also had some minor design flaws.

In a nutshell, the most common problems of the VXR 650 were as follows:

  • Aluminum impeller: The factory aluminum impeller was prone to getting damaged very easily by debris. Because of this, many owners replaced it with a stainless-steel aftermarket impeller.
  • Loud and “shaky” idle: The 2-stroke engine of the ski didn’t ensure smooth idling. Instead, it was quite loud and shook a lot while idling, but this was considered normal on these vintage power sources.
  • Aging oil lines: The oil lines were prone to aging and cracking on 2-stroke jet skis over time, and the VXR 650 was no exception. And only a little malfunction in the oil system could easily end in an engine seizure. Bypassing the entire oil system and switching to premix was the only way to prevent these issues.
