    Run it with the seat off with some WOT to 0 throttle runs and see if your shaft seal is spraying water.

    Remove the seats/fire extinguisher partition and leave them on a dock somewhere secure. Ride it for several runs up to top speed and then just chop the throttle to closed and look down inside of your engine bay [between your legs] to see if any water is spraying around in side it. The shaft seals are only pressurized when you chop the throttle at high speeds, the pump slows down and the intake grate is scooping water into the intake tract with no place for it to go. The seal, if it is bad will spray water inside the rear of the engine bay.
