    should be no water in the hull at all. check all water lines/hoses/bilge/exhaust (tighten all clamps and check hoses for splits)

    I would leave it tied to the trailer and back it down with the seat off. You should be able to see where the problem is. You need to also check the seals around the thru hull bearing for the drive line. These things had problems with the exhaust I believe being loose at clamps?
