2007-2010 Sea-Doo GTI SE 155 Review
By 2006, Sea-Doo had completely revamped its entry-level GTI family. The platform of the new GTI lineup was redesigned from scratch and housed a 4-stroke Rotax engine.The 2006 Sea-Doo GTI lineup included four models, the base GTI 130, the GTI Rental 130, and the GTI SE 130. In 2007, this family was expanded with the more advanced GTI SE 155.
The new model came standard with a speedometer, dual mirrors, reboarding step, premium footwell mats, water temperature sensor, ski tow eye, custom seat, and a more powerful 155 HP engine option.
Let’s get down to the nitty-gritty and talk about this Sea-Doo in detail!
‘07-’10 Sea-Doo GTI SE 155 Hull and Deck
Like its smaller siblings, the GTI SE 155 was built on an entirely-new Fiber Reinforced Plastic (FRP) composite platform measuring 127 inches in length, 49 inches in width, and 45.9 inches in height.
The dry weight of the GTI SE 155 was 747 pounds. In contrast, the dry weight of the 2-stroke GTI models varied between 623 and 700 pounds depending on the model.
The new 4-stroke GTI SE 155 was not only bigger and heavier but it also returned with greater capacities.
It could carry three riders and plenty of gear with ease. Its load capacity was 602 pounds, 66 pounds more than the capacity of the 2-stroke GTI line.
Its revamped deck featured a 15.9-gallon fuel tank, standard bow storage, and a roomy glovebox. The total storage capacity of the ski was 12.4 gallons.
This GTI platform remained from 2006 through 2010 without any significant changes.
In 2011, the Canadian manufacturer released its all-new GTI line including the top-of-the-line 2011 GTI SE 155.
‘07-’10 Sea-Doo GTI SE 155 Engine and Propulsion
The engine of the 2007-2010 Sea-Doo GTI SE 155 was a 4-stroke, 1494cc, SOHC, 3-cylinder inline Rotax 4-TEC rated at 155 HP. Interestingly, the GTI SE was available with both 130 and 155 HP engine options.
This Rotax 4-TEC power source debuted in the 2002 Sea-Doo GTX 4-TEC, but found its way into many other Sea-Doo models.

‘07-’10 Sea-Doo GTI SE 155 Performance
The GTI SE 155 was known to be an excellent beginner jet ski, and with good reason.
This tame ski had a reputation for great maneuverability, a predictable attitude, and good reliability.
Thanks to its 4-stroke, 155 HP engine, the ‘07-’10 Sea-Doo GTI SE 155 could hit about 55 mph in stock condition.
‘07-’10 Sea-Doo GTI SE 155 Problems
In a nutshell, the most common problems of the ‘07-’10 Sea-Doo GTI SE 155 were as follows:
- Awkward thumb throttle
- OPAS malfunctions
- Lack of a brake system
Unlike modern finger throttle levers, this outdated configuration offered less precise handling and caused massive hand fatigue on longer tours.Another problem with the GTI SE 155 was its deflective OPAS system, which would come into operation when it shouldn’t. Fortunately, it was relatively easy to remove.
It’s also good to know that this ski came without a brake system, since Sea-Doo’s iBR brake and reverse system was only available on the flagship skis from late 2008.
