I just rebuilt the top end of my 90 sea-doo sp and took it out to test it in the water, but it had a major lack of momentum. I will not say lack of power because when I did a compression test on the ski itg had 130psi per cylinder. When I first give it throttle it seems like it is about to take off, but then it seems to die off with only enough momentum to move the ski, but barely lift the bow out of the water. Could this be caused by the fuel pump or the fuel filter, or both? Also while I had it in the water I took the seat off to see if I could see anything that might be wrong (which I didn't) and I did not notice any water flowing through any of the small clear lines. Should I be able to see water flowing through these lines? I did notice water in the 2 larger lines from the side of the hull near the front, under the storage compartment, but that was it. If any one has any help to offer it is greatly appreciated. Yhank you in advance.
