1996-1997 Sea-Doo GTX 800 Review

Sea-Doo introduced its popular 3-seater 2-stroke GTX line in 1993. Over the years, this family underwent many different generations, including:

It’s safe to say that the 1996 Sea-Doo GTX 800 (a.k.a. GTX 787) was the first authentic 3-seater Sea-Doo PWC in history. (Its 3-seater predecessors were built on the small GS-style platform, which was only comfortable for two adults.)

The all-new GTX 800 was considered the most luxurious PWC of its time and with good reason.

It was built on a large, 3-seater platform measuring 122.8 inches in length, 47 inches in width, and 37 inches in height. This fiberglass body was larger than its outdated GS-style predecessor. It also had a more modern, rounded design.

The top deck featured curved lines and housed a large, 2-piece seat and three separate storage compartments. The industry-standard front storage was enhanced with a small glovebox and a watertight storage tray under the passenger seat.

Under the seat, you would also find the proven dual-carb Rotax 787 engine. This 782cc, 2-stroke, in-line twin was rated at 110 HP and came with many advanced features, including:

Engine power was delivered by a direct drive system to a Bombardier Formula water jet pump. This axial-flow, single-stage pump utilized bronze-alloy stator vanes and produced plenty of thrust.

Thanks to this advanced propulsion system and the powerful Rotax RAVE engine, the top speed of the Sea-Doo GTX 800 was about 53-55 mph in stock condition. What’s more, this ski could even hit 60-62 mph with some aftermarket performance modifications!

Its 15-gallon fuel tank offered a cruising time of 1 hour and 8 minutes, while its oil system utilized a 1.6-gallon oil reservoir.

The GTX 800 was one of the most powerful skis in Sea-Doo’s fleet and claimed to be the “most luxurious PWC” of its time.

Its stable hull and advanced features made the GTX a perfect “tow-PWC”, so it was no surprise that this model instantly became popular among wakeboard riders and tubers.

Standard features of the GTX 800 included:

  • Handlebar-mounted start/stop button
  • Large front storage
  • Glove box
  • 15-gallon built-in fuel tank
  • 1.6-gallon oil reservoir

The large and easy-to-read dashboard housed three separate gauges. You could find an analog speedometer with a low-oil warning light on the right.

The analog tachometer was installed on the left side and incorporated an engine overheat warning LED.

In the middle, you had the Sea-Doo-exclusive info gauge center. This innovative LCD multifunction gauge had many useful functions, which were as follows:

  • Engine hour meter
  • Clock/compass
  • Fuel level
  • Chronometer
  • Average speed
  • Current speed
  • Peak speed
  • Distance

  • Average speed
  • Speedometer
  • Tachometer
