🔍 Model Background

The 2003 Sea-Doo GTX 4-TEC series marked a turning point in personal watercraft design, as Sea-Doo fully embraced 4-stroke technology and introduced a new standard for performance, reliability, and environmental friendliness. The lineup included the GTX 4-TEC (naturally aspirated), GTX 4-TEC Supercharged, and GTX 4-TEC Limited Supercharged, each offering a unique blend of touring comfort and engine performance.

The base GTX 4-TEC featured a 1494cc Rotax 4-TEC 4-stroke engine delivering 155 horsepower. This model focused on smooth power delivery, low emissions, and fuel efficiency, ideal for recreational riders and long-distance touring. It also introduced Sea-Doo’s closed-loop cooling system, which helped prevent saltwater corrosion and engine overheating.

The upgraded GTX 4-TEC Supercharged used the same engine platform but added a factory supercharger, increasing output to around 185 horsepower. This version delivered quicker acceleration and higher top-end speed while maintaining the comfort and convenience of the GTX hull. It appealed to riders who wanted touring comfort with sport-level performance.

The top-tier GTX Limited Supercharged further enhanced the package with premium features like a depth finder, cover, glovebox organizer, and exclusive trim colors. It shared the same 185 HP supercharged engine but added refinement and extras for serious long-haul riders.

All three models rode on Sea-Doo’s full-sized GTX hull, known for its stability, spacious 3-up seating, and smooth handling in rough water. Standard features across the lineup included tilt steering, analog/digital gauges, OPAS (Off-Power Assisted Steering), and a reboarding step.

The 2003 GTX 4-TEC series laid the foundation for modern luxury-class PWCs and proved that 4-stroke performance could rival the excitement of 2-strokes—while offering better reliability, cleaner emissions, and quieter operation.
