2007 SEADOO GTX 155 5 HP SUPERCHARGER ENGINE 1500 cc 3 PASSENGERS JETSKI
The 2007 Sea-Doo GTX 155 is a 3-Passenger Style Personal Watercraft “PWC” equipped with an 1494cc, Liquid Cooled, In-line, SOHC, 4-Stroke Engine. It has a 4-blade Stainless Steel impeller and puts out 215HP.
The Sea-Doo RXP’s supercharged 4-stroke 3-cylinder Rotax SOHC with intercooler features a big-bore (100mm), short-stroke (63.4mm) design. Reduced piston travel means a longer engine life. The heads are a 4-valve design because the RXP mill is redlined at 8 grand. High-revving bike engines that spin at over 11,000 rpm benefit from 5-valve heads. Premium components, such as titanium valves, add to the durability equation, but that stuff doesn’t come cheap. Bombardier, the parent company for Sea-Doo, Rotax and other brands, needed volume to justify the engine investment. In addition to powering PWCs, the 4-stroke – dubbed 4 TEC – in various configurations is being bolted into everything from the company’s ATVs and snowmobiles to Sea-Doo sport boats.
