1994-1995 Kawasaki 750ST Review
Kawasaki 750ST Hull
Kawasaki introduced the ST for the 1994 model year, as the first 3-seater Kawasaki Jet Ski.
Since it was part of the 750 Jet Ski family, it was often referred to as the 750ST or ST 750.
To handle the weight of three riders, the 750ST was built on an all-new platform, measuring 122 inches in length, 46.5 inches in width, and 39 inches in height.
Compared to the 2-seater Super Sport (SS) family, this machine was 22.4 inches longer and 5.9 inches wider. Let’s face it, this was a significant difference that translated to more buoyancy and stability.
The dry weight of the 750ST was a whopping 529 pounds, 121 pounds more than the high-performing Xi Sport.Its top deck featured a large seat, standard bow storage, a rear storage pocket, and tiny glovebox.
Kawasaki 750ST Engine and Propulsion
The power source of the Kawasaki 750ST was a 2-stroke, 743cc, single-carb, vertical twin Kawasaki Jet Ski engine rated at 63 HP, the key features of which were as follows:
- 2-stroke, vertical twin architecture
- 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
Due to its underpowered engine, the top speed of the 750ST was only 40-42 mph, which made it one of the slowest Kawasaki Jet Skis ever made.
Although it was advertised as a 3-seater model, it could barely carry three adult riders.
It had enough power to get on a plane with one adult passenger or two small kids, but with three adults onboard it just struggled.
On top of that, it became very tippy and unpredictable, especially at lower speeds.
The propulsion system of the 750ST was an axial-flow, single-stage jet pump rated at a maximum thrust of 595 pounds.
Its fuel consumption was 7.1 GPH at WOT, so its 12.2-gallon fuel tank offered a cruising range of 72 miles or a riding time of 1 hour and 42 minutes.
Kawasaki 750ST Features
The 750ST came standard with many innovative features, including:
- Manual reverse
- Display panel with oil and fuel level warning lights, fuel indicator lights, and an engine overheating warning light
- Choke knob
- Fuel knob
- Handlebar-mounted start/stop buttons
- Shut-off switch with safety lanyard
- Front storage compartment
- Fire extinguisher compartment (under the storage case)
- Rear storage pocket
- Glovebox
- Tool kit
- Drain plugs
- Thumb throttle lever with a throttle limiter
- Tow hook
- Mooring cleats
- Rear grab handle
- Sponsons
- Underwater exhaust outlet
- Deck mats
This mechanical reverse included a foldable reverse bucket behind the jet nozzle and a reverse lever mounted on the right side of the deck.
The Kawasaki 750ST was marketed from 1994 through 1995 when it was phased out by the more powerful, dual-carb STS.
