Its performance was everything and more that I expected. Since then I have put 175 hrs. on it and the only thing I have done to it is chance spark plugs every 40-50 hours which is a must, and pour $40.00 US a gallon oil into it . For anyone interested, I have taken weekend rides of up to 380 miles on it and I can tell you it gets 10 miles per gallon with a 15 gallon tank for a total range of 150 miles. Now I should tell you this is if you stay under 5800 RPM, which is where it opens up reed valves fully and starts sucking up gas. It is still a good cruising speed of aprox. 50 mph. My brother bought the new 4-tec which gets around 6 miles per US gallon, but you dont have to pour 2 cycle oil into it at the tune of a quart to a tank like I do my DI. One of the other great thing about my 2001 GTX-DI is the removable front storage tub that you can store extra gear under , I put my tent and sleeping bag in it. I rode my brothers 4-tec and It definately rides somewhat smoother on choppy water but I dont like the OPAS steering although he seems to. Also my brother takes week long trips of up to 1200 miles on Seadoo and hasnt had the first break down. They are really dependable. As a matter of fact his old GTX millenium edition that he just sold had so many hours on it the hour meter rolled back to zero. And that was without ever turning a wrench on it!
After further evaluation of this watercraft I have the following to report. Originally I posted a followup to Flyboy's evaluation. I still stand by my original findings 100%. After returning this watercraft to the -dealer for evaluation and repair, I have the following information. 1) The spedometer on this watercraft is incorrect. The spedometer reads approximately 6-7MPH slower than actual speed. Original speed out of the fox was actually 56-57 MPH. (clocked by sherrif radar) 2) Fuel injectors out of the box were incorrectly setup to perform optimally. Dealer adjustment of the fuel injection system. Dealer correction of the fuel injection system produced an additionl 2-3 MPH depending on water conditions. After adjustmernt, top speed was 58-60MPH. depending on water conditions. 3) OPAS steering assistance while fantastic at minimal speeds does produce loss of top speed as every time the steering is moved off center position, you are in fact putting on a brake as the rudders move outward to assist steering thus producing a severe loss of MPH in gentle or sharp cornering. In addition, OPAS also hinders the system from spinning out. Spinning out is only possible if you are leaning far enough into the turn to lift the outside corner's rudder out of the water. Lastly...OPAS hinders the system's "out of the hole performance as unless the steering wheel is perfectly straight, than you are in fact giving the watercraft gas and brake at the same time. I have requested my OPAS system be removed from this watercraft. This sled is currently iat the dealer to have the OPAS system removed, and I will return to let any readers know what results the removal of the OPAS system produces. 4) This last downside to this watercraft is not solely applicable to the GTX DI. I have noticed this on several other 2002 model SeaDoo Watercraft. Pay particular attention to your seats. After only a few hours of riding, the se at begins peeling and flaking. Should this happen you should not have any problems getting the seat replaced. 4) while there are main big negatives to this sled, thes negatives only apply to those riders who are solely looking for speed and competitive type driving. For the rider who is looking for a smooth ride and stability, this watercraft is perfect for you. This is by far the smoothest riding and most stable watercraft I have ever ridden. 5)Out of the box, the GTX DI is faster than the GTX RFI, by maybe 2MPH. It is slower than the GTX. I have also ran against several other watercraft. comparing against other 3 seaters, so far I have found only the seadoo GTX to be faster by maybe 2-3 MPH. Once the OPAS system is removed, I think it would be closer. 6)Bottom line is if you are looking for speed without hassle, buy the seadoo GTX. If you are looking for the stability and a smooth ride (and a fair amount of speed) than the GTX DI is definately your choice. Just keep in mind to clock your watercraft against a boat or another watercraft where the spedometer works properly if you think yours is in question. The GTX DI is all in all a great watercraft for a beginner or older rider. For the more experienced rider who is looking for speed and horsing around, than the GTX DI may not be the product to purchase.
Having had a great deal of experience with Sea Doo watercraft I was initially excited to take delivery of my new 2002 GTX DI. The 2001 GTX DI was a true hot-rod with a perfect blend of speed and agility. The 2002 is the exact opposite. The hull has been changed to a deeper "V" and lengthened 6.3 inches (16 cm). The boat now measures 10'10" (331 cm) and contains an additional 50 pounds (12 kilos) of fiberglass. This plus the additional drag created by the O.P.A.S. rudder system significantly slows the machine down. My initial single rider top speed is a steady 48 mph (77.24 kph). The motor now had approximately 8 hours and top speed indicates 50 mph (80.47 kph). In all fairness the folks at Bombardier have relocated the speed sensor on the 2002 and a side by side test run against the 2001 GTX-DI showed an equivalent 58 mph (93.34) on the old speedo. Side by side “out of the hole” was nearly equal between the 2001 and 2002 models. At about 35 mph (56.33 kph), however, the 2001 runs away from the 2002. It’s top end is easily 6-8 mph faster…maybe more. The 2002 now has an OPAS rudder system which is programmed to retract at approx. 75% of max rpm. The good news is the 2002 GTX-DI is easier to back up than almost any watercraft or for that matter boat I have ever driven. The bad news is the OPAS system should retract at a far lower rpm. At mid speed ranges OPAS actually causes greater instability due to sudden yaw motions caused by the protruding rudders. At these speeds the directional control of the GTX-DI can be easily handled via normal steering of the jet nozzle…the OPAS is overkill and counterproductive. GTX models other than the DI and 4-TEC retain the former hull design which is already stable yet still quite agile for a three-seater. The 2002 GTX DI is (other than at mid-speeds)excessively stabile (SeaDoo's correspondence with me refers to this as "safer") to the point where they' ve truly removed the "FUN" from this machine. Full steering deflection at top speed won't even spin the thing out. The only way you can even get wet while riding this machine is by jumping off of it. SeaDoo also claims greater fuel efficiency with new design but had I wanted efficiency I would have bought a moped. What was a Corvette is now the Queen Mary. Unless you're shopping for a cruise ship I strongly advise against the hefty purchase price of this particular machine.
