1993 Sea-Doo GTX 580 Review

Sea-Doo launched the 1990 GT as its first three-seater runabout PWC.

This machine utilized a flat-bottom hull and a dual-carb “Yellow” Rotax 587 engine. This model was then carried over without any changes for the 1991 model year.

For the 1992 model year, the GT was rebranded to GTS, and this model remained the entry-level three-seater Sea-Doo until the Millennium.

In 1993, Sea-Doo released a more featured 3-seater PWC, the 1993 GTX. This model was almost identical to the 1993 GTS, except for having a more powerful twin-carb engine configuration. The GTX also had gauges, like an analog speedometer and a fuel gauge with a low-oil warning light.

Unlike the original flat-bottomed GS hull, the 1993 GTX 580 came with strakes for better stability and handling.

This revamped GTS/GTX hull was slightly smaller than its predecessor, as it measured 119 inches in length, 46.9 inches in width, and 37.4 inches in height.

The 1993 GTX was powered by a dual-carb “White” Rotax 587 engine. This 580cc, 2-stroke twin utilized a CDI ignition, oil injection, open-loop cooling system, and two Mikuni carburetors. Thanks to these advanced features, the ’93 GTX provided 60 HP.

In contrast, the base GTS with the single-carb Rotax 587 engine offered only 55 HP.

Aside from a different engine configuration and extra gauges, the 1993 GTX and GTS were basically identical.

Standard features of the 1993 Sea-Doo GTX 580 were as follows:

  • Electric start
  • Handlebar-mounted engine stop button
  • Tether cord
  • 8.7-gallon fuel tank
  • 95 oz. oil reservoir
  • Fuel tank reserve
  • Deck mats
  • Overheating warning device
  • Manual reverse
  • Removable storage compartment
  • Rear grab handle
  • Rear vent grill
  • Docking eyelets
  • Speedometer
  • Bile drain plugs
  • Fuel level gauge (with low-oil warning light)
  • Electric fuel level gauge
  • Injection oil low-level warning device
  • Water tank trap drains
  • Tool kit

The 1993 GTX 580 was only offered in the 1993 model year as Sea-Doo replaced it with the more powerful GTX 650 for the 1994 season.

Over the years, the 2-stroke Sea-Doo GTX family underwent many upgrades and generations, including:
