1995-1997 Kawasaki 900 ZXi Review and Specs [Video]

The Kawasaki 900 ZXi was the first 3-cylinder Kawasaki Jet Ski and it was manufactured from 1995 through 1997. It featured a 2-stroke, 891cc, crankcase reed valve, triple-carb, triple-cylinder engine rated at 100 HP. The 2-seater 900 ZXi was marketed as the mid-range model between the base 750 ZXi and the high-end 1100 ZXi.

Thanks to its innovative features, the 900 ZXi won the prestigious “Watercraft of the Year” award.

1995-1997 Kawasaki 900 ZXi Review

Kawasaki 900 ZXi Hull and Top Deck

Kawasaki released the ZXi line in 1995 as a high-performance, 2-seater family runabout, which included the entry-level 750 ZXi and the more powerful 900 ZXi. This line was completed in 1996 with the flagship 1100 ZXi.

These skis shared the same ZXi platform, measuring 108.7 inches in length, 42.1 inches in width, and 39.3 inches in height. Compared to the 3-seater STS, this body was 4.4 inches narrower and 13.3 inches shorter.

It housed a comfortable 2-rider seat, and a lot of storage space, including a roomy bow storage, a small storage pocket (glovebox), and an under-seat storage pocket.

The 900 ZXi shared a 3.5-quart oil tank and an 11.4-gallon fuel tank with the 750 ZXi. The latter was enlarged to 13.7 gallons for its final (’97) season.

The dry weight of the 900 ZXi was 558 pounds, which was significantly less than the dry weight of the 3-seater STS.

The ’95-’96 models shared the same color scheme, a painted purple hull and white top deck with green and purple accents.

In 1997, the ZXi 900 got an all-new red/white/purple dress with a painted red hull.

Sadly, the painted hull of the ZXi scratched very easily and even peeled off over time.

Kawasaki 900 ZXi Engine and Propulsion

The engine of the Kawasaki 900 ZXi was a 2-stroke, 891cc, vertical triple rated at 100 HP. This power source was the first 3-cylinder Jet Ski engine manufactured by Kawasaki.

The key features of this triple-carb Kawasaki 900 ZXi engine were as follows:

  • 2-stroke, vertical triple architecture
  • Crankcase reed valve configuration
  • 3 x Keihin CDK 38-29 carburetors
  • NGK BR9ES spark plugs
  • Oil injection system
  • Magneto CDI (Digital) ignition system
  • Open-loop cooling system
  • Electric starter
The main advantage of this power mill was its remarkable engine power since it delivered 100 HP but the 750 ZXi was only rated at 83 HP.

Engine power was delivered to an axial-flow, single-stage jet pump rated at a maximum thrust of 732 pounds.

Kawasaki 900 ZXi Features

The 900 ZXi came standard with many advanced features, including:

  • Innovative dashboard
  • Choke knob
  • Fuel knob
  • Adjustable trim
  • Handlebar-mounted start/stop buttons
  • Engine shut-off lanyard
  • Front storage compartment
  • Fire extinguisher compartment
  • Under-seat storage pocket
  • Front storage pocket (glovebox)
  • 3-rider seat
  • Seat latch
  • Tool kit
  • Drain plugs
  • Finger throttle lever
  • Throttle limiter
  • Adjustable rear-view mirrors
  • Tow hook
  • Mooring cleats
  • Rear grab handle
  • Sponsons
  • Underwater exhaust outlet
  • Deck mats
The ZXi also came with rich instrumentation, including:

  • Analog speedometer
  • Analog tachometer
  • Fuel gauge
  • Trim indicator
  • Cooling water temperature warning light
  • Oil level warning light
While the 750 ZXi lacked a speedometer, the 900 ZXi came standard with this key feature.

Aside from this small difference and the engine options, these skis were basically identical.

Kawasaki 900 ZXi Performance

Thanks to its lively 100 HP engine and small, 2-seater hull, the ZXi got on plane fairly easily and topped out at 54-55 mph.

Its claimed fuel consumption was 9.8 GPH at WOT, so its 11.4-gallon fuel tank offered a cruising range of 62.8  miles or 1 hour and 10 minutes of fun.

It could handle the weight of two riders but offered less stability than the bulkier 3-seaters.

Therefore, the 900 ZXi was primarily recommended for solo rides.

Sadly, its hull was quite unpredictable and prone to porpoising, so it got a lot of criticism from riders.

Kawasaki 900 ZXi Problems

It is safe to say that the biggest problems of the Kawasaki 900 ZXi were as follows:

  • Lack of a reverse system
  • Complex, high-maintenance engine
  • Poor electrical box and trim box sealing
  • Wear ring was prone to swelling up
  • Poor hull painting
  • Wrong hull design
One of one the biggest flaws of the 900 ZXi was arguably the lack of a reverse system.

While the 3-seater STS and STX families came standard with a mechanical reverse, the entire ZXi line was marketed without this important system.

Another problem of the 900 ZXi was its 3-cylinder, triple-carb engine configuration, which added a lot of complexity to the ski.

Compared to the twins, the tiple 900 ZXi required more maintenance plus it was harder to rebuild after an engine seizure. It also required a lot of “carb work” since rebuilding and tuning its carburetors required more expertise (and patience).

The sealing of the trim box and electrical box was also prone to getting brittle over time. Once the water got into these boxes it caused corrosion and various other issues.

Another very common problem of the 900 ZXi was its “swelling” wear ring. The manufacturer used a non-replaceable wear ring in these models, which was basically a sleeve inside the pump housing.

When salt water found its way between the wear ring and the pump housing, the corrosion caused the ring to “swell.”Since the clearance between the impeller and this ring was very tight, the blades often cut into the surface of the ring. In the worst-case scenario, the wear ring blocked the impeller, causing the entire jet pump to lock up.

The hull of the 900 ZXi had a tendency to porpoising in stock condition, which could be easily fixed by installing aftermarket sponsons or a longer ride plate.It was also quite unpredictable especially at higher speeds, which caused many headaches for riders.

On top of that, the hull of the 900 ZXi was painted and this was prone to scratching or “shedding” over time, making the white Gelcoat visible.
