The Kawasaki Ultra 130 D.I. was a fuel-injected configuration of the carbed Ultra 150, which was manufactured from 2001 through 2004. It shared its hull and top deck with the Ultra 150 but borrowed its 1071cc, 130 HP, direct-injected engine from the 1100 STX D.I.

2001-2004 Kawasaki Ultra 130 D.I. Review

Kawasaki Ultra 130 D.I. Hull and Top Deck

Kawasaki introduced the ZXi series as its high-performance 2-seater PWC line in 1995, including the 750 ZXi, 900 ZXi, and its top-of-the-line 1100 ZXi.

Around the Millennium, the new ZXi-based Jet Skis hit the water, labeled as Ultra 150 and Ultra 130 D.I. The former was a more powerful carbed configuration, while the Ultra 130 D.I. featured a smaller, fuel-injected engine.

Although the Ultras officially weren’t members of the ZXi family, their hull and top deck design were based on the ZXi.

In terms of dimensions, this revamped Kawasaki Ultra platform was 113.8 inches long, 44.4 inches wide, and 40.5 inches high. It was 5.1 inches longer and 2.3 wider than standard ZXi models in order to handle the increased performance.

This hull was made of hand-laid fiberglass and featured a bulkhead construction, ensuring less weight and less structural flex.

It also enjoyed a steeper (22-degree) deadrise, stretching from the bow towards the pump intake.

The rounded keel of this deep-V hull effectively cut through the waves while the molded spray deflector kept a significant amount of waterspray away from riders.

The Sheet-Molded Compound top deck of the Ultra 130 D.I. was carried over from the Ultra 150 without any significant changes. It featured padded handlebars, a stepped 2-rider saddle, and a pair of performance sponsons.

Storage compartments included a glovebox, an under-seat storage case, and a 5.5-gallon bow storage, housing a removable bin and a fire extinguisher compartment.

The oil and fuel caps were also covered by the front hood, which featured a hydraulic lifting cylinder.

Kawasaki Ultra 130 D.I. Engine and Propulsion

The engine of the Kawasaki Ultra 130 D.I. was a 2-stroke, 1071cc, 3-cylinder, fuel-injected Kawasaki marine engine. As the name suggests, this power mill delivered a maximum power of 130 HP at 7,000 RPM.

This power source was also known as the direct-injected 1100 Kawasaki Jet Ski engine, and had the following characteristics:

Unlike its standard carbed counterparts, the Ultra 130 D.I. featured a Ficht direct-fuel injection system.

This system was controlled by the Engine Management Module (EMM), which monitored everything from the external conditions to the engine operation.

Based on these factors the EEM determined the optimal fuel mapping (a.k.a. fuel delivery curves), which translated to a smooth operation and easy starts.

This engine was paired with a standard axial-flow, single-stage jet pump, housing a stainless-steel, 3-blade, oval-edge impeller. This high-capacity pump delivered a maximum thrust of 851 pounds.

Although this ski delivered 15 HP less than the carbed Ultra 150, it offered a crisper throttle response and a smoother powerband.

On top of that, it used significantly less fuel and half as much oil as a carbureted engine, Boats.com reports.

Kawasaki Ultra 130 D.I. Features

Although the Ultra 130 D.I. came with fewer bells and whistles than the high-end luxury STX 1100 D.I., it packed many innovative features, including:

The digital instrument panel of the Ultra 130 D.I. had many useful functions, including:

  • Speedometer
  • Tachometer
  • Clock/Time/Trip/Hour meter display
  • Trim indicator
  • Fuel level gauge
  • Low fuel warning light
  • Water temperature symbol
  • Engine oil level gauge
  • Low oil warning light
  • Battery symbol
  • Check engine symbol

Kawasaki Ultra 130 D.I. Performance

The Kawasaki Ultra 130 D.I. was often referred to as the motorcycle of the water, and with good reason.

It was lightweight, fast, and offered great cornering abilities. Although it was marketed as a 2-seater PWC, it was more of a solo Jet Ski.

In terms of performance numbers, the top speed of the Ultra 130 D.I. was 63-64 mph out of the box. With some aftermarket performance parts, it could be pushed into the ballpark of 70-75 mph!

Its remarkable power was paired with great cornering abilities and stability.

The claimed fuel consumption of the Ultra 130 D.I. was 10.8 GPH at full throttle, so its 15.06-gallon fuel tank offered a cruising range of 80 miles or 1 hour and 23 minutes of fun.

In contrast, the fuel economy of the thirstier carbed Ultra 150 was 13.3 GPH at WOT, which was a difference of 2.5 gallons per hour.

Just like its carbed brother, the Ultra 130 D.I. also came with a manually adjustable trim system intended for adjusting the vertical angle of the jet nozzle.

Although this model was very popular among riders, some found it unpredictable in rough waters.

Fortunately, these handling issues could be reduced with aftermarket ride plates and sponsons.

Kawasaki Ultra 130 D.I. Problems

It’s safe to say that the most common problems of the Kawasaki Ultra 130 D.I. were as follows:

  • Complex, fuel-injected engine
  • Lack of a reverse system
  • Improper shut-off switch location
  • Short-lived pump bearings
  • Aging oil lines
  • The oil injection system was hard to remove

One of the biggest flaws of the Ultra 130 D.I. was arguably its complex engine. Its Ficht direct-fuel injection system was much harder to troubleshoot and tune than regular carburetors.

What’s more, while the 3-seater models came standard with a reverse system, this important feature wasn’t available on the Ultra 130 D.I., even as an option.

Its shut-off valve was also located too close to its trim button, creating a risk that you could accidentally shut off the engine while adjusting the trim.

Another problem with this ski was its hungry jet pump, which ate the pump bearings in just 25-30 hours.

The factory oil lines were also prone to getting brittle while aging in many vintage Jet Skis, and the 130 D.I. was no exception.

Replacing these oil lines was a fairly simple maintenance task, but removing the complete oil system was much harder on this model.

This is because the oil system was used to lubricate the crankshaft as well, so removing it was not possible.
