'01 GTX DI with 70 hours on it. I just bought this 2 weeks ago. Ran good for about 10 minutes, now it will only go about 35 mph, at 6600rpm. The seadoo mechanic has checked everything he can think of and called the manufacturer. Good compression, good fuel pressure, new gas, checked injectors, rave valve, water regulator, swapped in a new voltage regulator. The fuel that was in it did have some water in, which he drained and replaced. Any ideas?
