Finally figured out how to change the fuel pump. I went ahead and bought a Quantum fuel pump. Put the seadoo into the water today (Florida), and it didn't work and I had to paddle back to the dock. Tried it again, it fired up, I kept the throttle pinned for a while, it bogged of and on for 5 minutes and then took off. I drove for another 2 hours after that to burn off the tank of 8 month old gas. But the ski isn't running at full power. It bogs a bit and I can only get about 6500 RPM out of it, occasionally it would go to 7000 RPM then cut back. Top end is only 45 mph. The exhaust smells quite a bit also, not very clean. Could this be the supercharger? I'm going to change the plugs, and check the supercharger. Hope I don't have to rebuild it. The seadoo has 170 hours on it, don't know if the supercharger has been serviced or not. It's a 2006 GTX.
