I just bought a 2001 Seadoo Rx from a guy last week. The ski had been sitting in his garage for the past year or two. I took it out to the lake, put gas and redline 2 stroke racing oil into it (same kind as he already had in it), put it in the water and it fired up no problem. Let it warm up for a bit and started taking it out into the open water. It had no power what so ever, I had the throttle held wide open for about 3 minutes only going about 20mph. All of a sudden the true power finally kicked. I'm guessing the old gas finally cleared out of the lines and carbs. I was doing a steady 60mph after that and it had consistent power. My only problem was when I tried to cruise at low speeds. 5-10mph it kept bogging down to idle then coming back up. It even died a couple of times while trying to cruise through the low speed zones at the lake. But if I go half or full throttle it runs perfect without hesitation. Also when the ski is out of the water hooked up to the water hose it idles at 3300-3400rpms. Is that too high? All help would be very much appreciated!
