1996-2003 Kawasaki 1100 ZXi Review

Kawasaki 1100 ZXi Hull and Top Deck

Kawasaki released the ZXi series in 1995 as a high-performance 2-seater runabout line.

The first members of this family were the base ’95 750 ZXi and the more powerful ’95 900 ZXi, which was completed with the top-of-the-line 1100 ZXi in ’96. As their names suggest, they utilized 750cc, 900cc, and 1100cc engines, respectively.

They shared most of their features and the small ZXi platform, measuring 108.7 inches in length, 42.1 inches in width, and 39.3 inches in height. Compared to the 3-seater STX line, it was 4 inches narrower and 13.4 inches shorter.

This hull also housed a smaller, 2-rider seat, and a plethora of storage spaces including front storage, an under-seat storage bin, and a small storage pocket (glovebox) in front of the rider.

The ’96 1100 ZXi shared its 3.5-quart oil tank with its smaller brothers, which was replaced by a 4.0-gallon unit for 1997. The dry weight of the machine also jumped that year from 584 to 598 pounds.

Aside from these minor changes and a carb upgrade on the ’98 model, Kawasaki marketed the ZXi from 1996 through 2003 without any significant changes.

The different color schemes of each model year were as follows:

1996 – Hull: White, Deck: Red/Grey/Purple, Seat: Purple, Decals: White/Grey/White

1997 – Hull: White, Deck: Red/Black, Seat: Grey, Decals: Grey/White

1998 – Hull: White, Deck: Yellow/Black, Seat: Black, Decals: White/Purple

1999 – Hull: White, Deck: Yellow/Purple, Seat: Yellow/Black, Decals: Black/Yellow

2000 – Hull: White, Deck: Yellow/Black, Seat: Black, Decals: Black/Purple

2001 – Hull: White, Deck: Yellow/Black, Seat: Black, Decals: Black/Purple/Yellow

2000 – Hull: White, Deck: Yellow/Black, Seat: Black, Decals: Black/Purple

2002 – Hull: White, Deck: White/Black, Seat: Black, Decals: Black/Grey/Red

2003 – Hull: White, Deck: White/Blue, Seat: Blue, Decals: Black/Blue/Yellow

Since each model year had a unique dress, identifying a Kawasaki 1100 ZXi is fairly easy.

The key advantage of this model was its white Gelcoat hull, which proved to be much more resistant to scratches than the painted hull of the 900 ZXi.

Kawasaki 1100 ZXi Engine and Propulsion

The engine of the Kawasaki 1100 ZXi was a 2-stroke, 1071cc, vertical triple marine engine. This power source was the first Kawasaki Jet Ski engine that exceeded a whopping 1000cc. It was rated for 120 HP, while the 900 ZXi and the 750 ZXi delivered 100 and 83 HP, respectively.

The key features of the Kawasaki 1100 ZXi engine were as follows:

  • 2-stroke, vertical triple architecture
  • 3 x Keihin carburetors
  • NGK BR9ES spark plugs
  • Crankcase reed valve configuration
  • Oil injection system
  • Magneto CDI (Digital) ignition system
  • Open-loop cooling system
  • Electric starter

In the ’96-’97 model years, the 1100 ZXi housed three Keihin CDK-38-29 carburetors, which were upgraded to Keihin CDCV 38 carbs in ’98.

The propulsion system of the ski was an industry-standard axial-flow, single-stage jet pump, housing a 3-blade impeller.

The maximum thrust of this high-capacity pump was a remarkable 803 pounds.

Kawasaki 1100 ZXi Features

The 1100 ZXi came standard with many advanced features, including:

  • Innovative dashboard
  • Choke knob
  • Fuel knob
  • KATS – Kawasaki Automatic Trim System
  • 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
  • Dual 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 base 750 ZXi came without a speedometer, the more advanced 900 ZXi and 1100 ZXi were already equipped with this key feature.

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

Kawasaki 1100 ZXi Performance

Thanks to its high-performance 120 HP engine and small 2-seater hull, the 1100 ZXi could hit a whopping top speed of 58 mph. This amazing machine accelerated extremely quickly and could outperform the majority of stock PWCs of its time.

To feed the horses, the ski burned a significant amount of gas.

Its claimed fuel consumption was a whopping 12.2 GPH at WOT, so its 13.7-gallon fuel tank lasted only about an hour if you were hard on the throttle.

To be more precise, the claimed fuel range of the ski was 66 miles or 1 hour and 8 minutes at WOT.

This ZXi could handle the weight of two lighter riders but offered less stability than its 3-seater counterparts, so it was mainly recommended for solo rides.

Regarding handling, its hull design got a lot of criticism due to its unpredictability. It was prone to throwing riders off during high-speed turns, which was neither safe nor convenient!

These handling issues could be mitigated with some aftermarket mods and updates, but couldn’t be completely eliminated.

The 1100 ZXi had a tendency to porpoising, which could be reduced by installing a longer ride plate or aftermarket sponsons.

Kawasaki 1100 ZXi Problems

It is safe to say that the biggest problems of the Kawasaki 1100 ZXi were as follows:

  • Lack of a reverse system
  • Complex engine
  • Poor electrical box and trim box sealing
  • Wear ring was prone to swelling up
  • Unpredictable hull

Unlike its 3-seater brothers, the 1100 ZXi was marketed without a reverse system, which translated to harder handling.

Another problem of the 1100 ZXi was its complex 3-cylinder, triple-carb engine. Although this power mill was fairly reliable in stock condition, it required more attention and care than its twin siblings.

As you can imagine, tuning and rebuilding three carburetors required more time and expertise.

The sealing on its electrical box and trim box was also prone to aging and cracking over time. Once the water found its way into these boxes it caused various issues including electrical malfunctions and corrosion.

The “swelling” wear ring issue was also a common problem on the ZXi series, and the 1100 ZXi was no exception. What does this mean?

Kawasaki used a non-replaceable wear ring in these skis, which was a sleeve mounted into the pump housing.

When salt water got between the pump housing and the wear ring, the latter started to swell due to corrosion.

In other words, the tight clearance between the ring and the impeller decreased to zero, causing the impeller blades to cut into the ring. In many cases, the impeller was completely blocked, locking up the engine itself.

As we’ve discussed, the ZXi hull was very unpredictable and prone to porpoising in stock condition.
