  • 2008 Sea-Doo GTX
  • Year:


The 2008 GTX has two power options. One for the 155 hp version: a 155 hp Rotax 4-TEC engine, and the other one for the 215 hp version: a 215 hp Supercharged Intercooled Rotax® 4-TEC® engine.

Both engines provides reliable performance in fresh or salt water, increased torque at low RPM, optimized power at all RPM levels and throttle positions.
