Sea-Doo GTX Millennium (951) Review

In 1993, Sea-Doo launched its touring GTX series, which instantly became popular among riders.

The high-end engines combined with great capacities and luxury features made the GTX series the flagship Sea-Doos each year.

Over the years, the 2-stroke GTX family underwent many different generations, which were as follows:

Sea-Doo completely redesigned its models for the Millennium, and the high-end GTX series was no exception.

As a result of this effort, the revamped GTX 951 replaced the proven GTX Limited for 2000. Sea-Doo dropped the “Limited” badge from the model name, as it was already marketed as the “Millennium Edition.”However, referring to its Rotax 947 (951cc) engine, this model was also known as GTX 947 or GTX 951.

The new GTX platform was 1.2 inches longer, 1.4 inches wider, and 4.9 inches higher than its predecessor. The dry weight of the machine also jumped from 645 pounds up to 662 pounds.

This large hull housed the proven dual-carb Rotax 947 (951cc) Rotax twin engine, which came with many advanced features, including:

The GTX Millennuim produced an amazing 130 HP thanks to these advanced features. Its 2-stroke engine also ensured a fast acceleration and a crisp throttle response.

Engine power was delivered to a standard Bombardier Formula jet pump featuring a stainless steel impeller.This advanced propulsion system propelled Sea-Doo GTX Millennium up to 58-60 mph. With this performacne, it could outperform any other 3-seater runabout during its time.

The fuel consumption of the craft was about 14.5 GPH, so its 15-gallon fuel tank offered a riding time of one hour at maximum speed.

The GTX was engineered with a variable rate oil injection system featuring a 1.6-gallon oil reservoir for the most effective lubrication.

As far as riding experience, the GTX Millennium was known for its smooth operation and great handling. Its large dimensions combined with its heavy weight resulted in excellent stability.

Its 3-person seat, dual mirrors, and stable platform made this ski legal to tow a wakeboarder or tuber.

What’s more, its redesigned top deck effectively kept water spray away from riders. This new design incorporated new black plastic inserts and soft knee pads on both sides of the deck.

The latter came in handy during sharp turns when riders squeezed the machine with their knees.

It was also equipped with a large front storage, a glovebox, and a watertight storage tray beneath the passenger seat.

Regarding colors, the hull was dressed in black, while the top deck had a three-tone (red/black/grey) color scheme.

Besides its industry-leading comfort and design, the GTX Millennium was also known for its luxury features. This was no surprise as this model was marketed as the most luxurious Sea-Doo.

Standard features of the Sea-Doo GTX Millennium included:

  • Handlebar-mounted start/stop button
  • Front storage compartment
  • Rear storage basket
  • Glove box
  • 15-gallon built-in fuel tank
  • 1.6-gallon oil reservoir

The large dashboard incorporated both an analog and a digital gauge.

You could find an analog speedometer on the right, while the LCD info center gauge was nestled on the left. This innovative multipurpose gauge had many useful functions, which were as follows:

  • Clock
  • Tachometer
  • Speedometer
  • Peak speed
  • Average speed
  • Trip meter
  • Engine hour meter
  • Water temperature
  • Chronometer
  • VTS (if so equipped)
  • Fuel level
  • Low fuel
  • Low oil
  • Low voltage
  • Overheating
  • Maintenance information
  • Clock/compass

Besides this carbed model, the fuel-injected GTX RFI and GTX DI were also offered in the early 2000s.

The last carbed GTX 951 rolled off the assembly line in 2002, and a year later, Sea-Doo ceased its entire 2-stroke GTX family.
