1992-1995 Kawasaki 750SX Review and Specs [Video]

The Kawasaki 750SX was the flagship stand-up Jet Ski in Kawasaki’s fleet from 1992 through 1995. It shared its 2-stroke, 743cc, vertical twin engine with the sit-down runabout 750SS but was built on a lively stand-up hull. It was replaced by the more powerful, twin-carb 750SXi, which offered an extra 12 HP.

1992-1995 Kawasaki 750SX Review

The 750cc Kawasaki stand-up jet ski family included three models, which were as follows:1992-1995 750SX

1995-1997 750SXi   

1998-2000 750SXi Pro

In this post we’ll review the single-carb 750SX, but you can find out more about its siblings by following the links above.

Kawasaki 750SX Hull

Kawasaki introduced the high-performance 750SX for the 1992 model year, as the successor of the discontinued 550SX.

But contrary to popular belief, this model didn’t share the same platform as the ’91-‘93 650SX.Instead, the 750SX utilized a custom hull measuring 87 inches in length, 27.6 inches in width, and 26.8 inches in height. The dry weight of the machine was 317.5 pounds and it housed a 4.2-gallon fuel tank, which was upgraded later to 5 gallons.

In contrast, its smaller brother (650SX) only weighed 282 pounds and its dimensions were slightly smaller as well.

The predecessor of the 750SX was the proven 550SX built on the proven JS platform. But compared to this outdated ski, the innovative 750SX was far more maneuverable and featured a fresh design.

Also, it came with a more powerful engine and a lot of innovative features.

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

Kawasaki 750SX Engine and Propulsion

The power source of the Kawasaki 750SX was a 2-stroke, single-carb, “small-pin,” 743cc, vertical twin Kawasaki marine engine rated at 63 HP. It was also engineered with many advanced features, including:

  • 2-stroke, vertical-twin, crankcase reed valve configuration
  • Single Keihin CDK 40-34 carburetor
  • NGK BR8ES spark plugs
  • Oil injection system
  • Magneto CDI ignition system
  • Open-loop cooling system
  • Electric starter
  • “Small pin” engine variation
  • Ported for more bottom end
While the engines of the successor SXi and SXi Pro were ported for high top end speeds, the 750SX was ported for more bottom end power, so its top speed was only 43 mph.

Thanks to its advanced features, this engine was not only more powerful, but it was also much more reliable than its predecessors.

The propulsion system of the 750SX was an axial-flow, single-stage jet pump housing a 3-blade aluminum impeller. This unit converted engine power into a maximum thrust of 551 pounds.

The fuel consumption of the ski was 6.1 GPH at WOT, so its 5-gallon fuel tank ensured a cruising range of 36 miles or a riding time of 50 minutes.

Kawasaki 750SX Features

The 750SX came standard with many advanced features, including:

  • Handlebar-mounted start/stop button
  • Control panel
  • Choke knob
  • Fuel valve knob
  • Starter interlock switch
  • Thumb throttle
  • Throttle limiter
  • Automatic bilge pump
  • Fire extinguisher compartment
  • Storage compartment
  • Underwater exhaust outlet
  • Deck mats on the tray and the rails
  • Chin pad
The control panel was planted in front of the tray and featured the engine cover latch, a choke knob, and a fuel valve knob.

Keeping safety and comfort in mind, the start/stop buttons were mounted on the left handlebar, while the thumb throttle was nestled under the right.

The latter was engineered with a special throttle limiter intended to cut engine power for novice riders.

The fuel tank cap of the 750SX was hidden under a cover on the front portion of the top deck, while the oil tank cap was placed inside the engine compartment.

After four years of production, the 750SX was phased out by the more powerful, twin-carb 750SX.
