2009 Sea-Doo GTX Limited iS 260 Review

By 2009, Sea-Doo had expanded its popular GTX line with the all-new GTX Limited iS 255. Its siblings were the base GTX 155 and the mid-range GTX 215.

These skis shared the same S3 hull, but the Limited iS 255 stood out with its unique suspension system, a special 2-piece top deck, and a high-performance engine.

After only one year of production, its engine power was increased to 260 HP and the GTX Limited iS 260 was born.

Let’s get down to the nitty-gritty and talk about this model in detail!

Sea-Doo GTX Limited iS 260 Hull and Deck

Just like any modern Sea-Doo GTX, the Limited iS 260 was also built on the innovative S3 hull.It featured a deep-V design with a narrow chine that could easily cut through small waves, offering comfortably smooth rides in all water conditions.

Made of composite fiberglass, the Sea-Doo S3 hull was 19% lighter than its competitors.

Regarding dimensions, the GTX Limited iS 260 measured 139 inches in length, 48 inches in width, and 44/50 inches in height.

The dry weight of the machine was a whopping 980 pounds, 155 pounds heavier than the base GTX 155.

For maximum comfort, it came standard with a wide range of innovative features including splash deflectors, retractable mooring lines (a.k.a. “Speed Ties”), and a bolstered touring seat.

It also enjoyed an 18.5-gallon gas tank, a watertight removable front storage bin, a swim platform storage, and a glovebox with an organizer.

Its overall storage capacity was 16.4 gallons while its load limit was 500 pounds, 100 pounds less than other full-size Sea-Doos.

Sea-Doo GTX Limited iS 260 Suspension

There’s no question that the most exciting feature of the Limited iS 260 was its Sea-Doo-exclusive Intelligent Suspension system.The main idea behind this innovation was to isolate riders from the negative impact of rough waters.

As far as operation is concerned, the Sea-Doo Intelligent Suspension was a mechanical system featuring one heavy-duty spring and one Fox PS6 Racing shock absorber mounted between the fixed lower deck and the moving upper deck. Its total suspension travel was 6 inches.

It could be adjusted to fit the number of passengers and different riding conditions.

Riders could select from nine settings or even the comfort level of the auto-calibration by pressing a handlebar-mounted control button.

Sea-Doo GTX Limited iS 260 Engine and Propulsion

As the name suggests, the power source of the Sea-Doo GTX Limited iS 260 was the 260 HP variant of the 4-stroke, 1494cc, SOHC, 3-cylinder inline Rotax 4-TEC engine.

Sea-Doo GTX Limited iS 260 Features

The Sea-Doo GTX Limited iS 260 came with a lot of advanced features, including:

It also came standard with the exclusive “Limited Package,” which included the following useful accessories:

Sea-Doo GTX Limited iS 260 Performance

The Sea-Doo GTX Limited iS 260 was known for a smooth operation and outstanding comfort.

Its revolutionary suspension system offered very comfortable rides even in choppy water conditions.

Riding position could be tailored with the adjustable handlebar, which also moved the dashboard up and down. Therefore, the gauges and control LEDs were never blocked from your sight.

Thanks to its incredible 260 HP engine option, GTX Limited iS 260 topped out at 65-67 mph under ideal conditions.

Engine power could be tamed using the riding modes of the Intelligent Throttle Control (iTC) system.

Sea-Doo GTX Limited iS 260 Problems

It’s safe to say that the biggest flaws of the GTX Limited iS 260 were as follows:

  • It was hard and expensive to work on and repair
  • Various electrical issues
  • iBR malfunctions
  • Rubber-coated driveshaft
  • Low storage capacity
Interestingly, one of the biggest flaws of the GTX Limited iS 260 was caused by its complex suspension system. For example, the bolts on its base were prone to breaking, and replacing them wasn’t an easy job.

Due to its unique “two-deck architecture,” the engine was planted in an enclosed compartment.

This plastic box not only made the engine hard to work on, but it also didn’t allow the engine to dry out after rides.

Therefore, the engine was wrapped in an enclosed space that kept moisture in all the time. This humidity caused a lot of corrosion on the fuses, wiring harnesses, and other electrical parts.

Plus, some of the wiring harnesses were mounted on the bottom of the hull, which was a clear design flaw. Let’s face it, it’s never wise to soak electrical parts in bilge water!

Because of these, the ski was notorious for various electrical issues, causing a lot of headaches for owners.

On top of that, the upper part of the deck had to be removed before any major engine repairs could be done.

The iBR brake and reverse also had many issues on the 2009-2011 iBR Sea-Doos, and the GTX Limited iS 260 was no exception.

This model was also known for its defective rubber-coated driveshaft. This coating would come off over time, which would cause damage to the impeller.

Consequently, if you are in the marketplace for a used Sea-Doo, you should steer clear of the GTX Limited iS 260 and any other suspension Sea-Doo.

Instead, you should take a close look at the naturally-aspirated models manufactured after 2011.
