The 2002-2003 Sea-Doo GTX DI was the final 2-stroke GTX model in Sea-Doo’s fleet. This PWC inherited its direct-injected Rotax 947 DI engine from its predecessor but shared its platform with the all-new 4-stroke GTX models.

If you want to learn all about the last fuel-injected 2-stroke Sea-Doo, this post is for you.

2002-2003 Sea-Doo GTX DI Review

The legendary 2-stroke Sea-Doo GTX family was introduced for the 1993 model year. Over the years, this line underwent many different generations, including:

In 2002, Sea-Doo introduced its all-new GTX platform on the innovative 4-TEC GTX line. Surprisingly, the 2002 GTX DI was also given this new body, measuring 130 inches in length, 48 inches in width, and 44 inches in height.

This means that this new platform was 6 inches longer and 2 inches taller than its predecessor. Besides the increased dimensions, it featured a much more modern design and far better capacities.

The load limit jumped from 353 to 600 pounds, resulting in improved stability under heavy load.  As a side effect, the dry weight of the ski also increased from 680 up to a whopping 715 pounds.

The top deck of the GTX was also completely redesigned and featured sleek-looking lines. Its smaller hood got a more modern, shiny air intake and a semi-transparent gauge cover.

The ski’s 2-piece seat also returned with a more modern, bolted design.

Other features like the 15-gallon fuel tank, the 1.6-gallon oil reservoir, and the Bombardier Formula jet pump were carried over from the previous year without any changes.

The power source of the ’02-’03 Sea-Doo GTX DI was the advanced direct-injected Rotax 947 DI, inherited from the 2001 model. This 952cc, 2-stroke Rotax twin featured direct orbital fuel injection, oil injection, an open-loop cooling system, and the innovative RAVE exhaust valves.

As the name suggests (DI= Direct Injection), this unit utilized a “real” direct fuel injection system. This engine was equipped with a secondary system designed to atomize the fuel before injecting it into the top of the cylinder heads.

Therefore, the 947 DI engine used both a fuel pump and an air compressor to boost the pressure and inject the fuel into the high-pressure side of the engine.

(In contrast, the semi-direct RFI (Rotax Fuel Injection) only used a fuel pump and injectors to inject the fuel into the low-pressure side.)Although the innovative DI direct-injection system was ahead of its time, it added a lot of complexity to the engine. Because of this, the Rotax 947 DI engine was much harder to troubleshoot and repair than its RFI and carbed brothers.

Therefore, if you are in the marketplace for a vintage 2-stroke Sea-Doo GTX, you may want to stay clear of the GTX DI models.

The complex engine in these skis provides great fuel economy and outstanding performance – as long as it’s running. But should there be any malfunction, a special scanner tool is required to diagnose and troubleshoot the issue.

This means that the DI engine is not easy to fix or even maintain in your garage. Therefore, it’s recommended that you choose a 4-stroke or a carbed 2-stroke Sea-Doo instead.

Due to its larger “4-TEC” body, the top speed of the 2002-2003 GTX DI was slightly slower than the ’01 model. Under ideal conditions, it topped out at 52-53 mph.

Standard features of the 2002-2003 Sea-Doo GTX DI included:

  • Handlebar-mounted start/stop button
  • Handlebar-mounted MODE and SET buttons
  • Large front storage
  • Glove box
  • Under-seat storage tray with spare spark plug holder
  • 15-gallon built-in fuel tank
  • 1.6-gallon oil reservoir
  • Electric start
  • Tether cord
  • 2 gauges (speedometer, multi-gauge)
  • Fender cleats
  • O.P.A.S. Off-Power Assisted Steering
  • Overheating warning device
  • Bow and stern eyes
  • Ski tow eye
  • Bilge drain plugs
  • Sponsons
  • Rear grab handle
  • Manual reverse
  • Large, 2-piece seat with a seat strap
  • Tool kit
  • D.E.S.S. security system
The large dashboard utilized an analog speedometer and an LCD multipurpose gauge with many useful functions.

The buttons on the multi-gauge had also been relocated from the handlebar cover to the left handlebar, right below the start/stop button.

Sea-Doo offered the GTX DI with the new 4-TEC platform from 2002 through 2003.

By 2004, the Canadian manufacturer dropped each 2-stroke GTX model from its fleet to make room for the more innovative 4-stroke skis.
