    Water in Hull when Cold Engine GP1800

    Hello,

    i do have an Problem since my 2020 GP1800 is new... i build an stage 2 when new, never rode stock

    I do got about 1 inch water in the hull when the engine is cold in the first 10 minutes of riding...after that no more water come in even when i ride 2 hours...

    so that means something with the exhaust because when it heats up it is "sealed"

    i did check ALL Hose Clamps and all screws on the Exhaust... i do have an Aquasport O2 Sensor as well and changed the gaskets to OEM Steel ones.... same thing.... first 10 Minutes water comes in and dont get more in the hole Day...

    some ideas ?

    thanks in Advance

    Mount a GoPro type camera and flashlight (or two) inside the hull. Do a short test ride.

    Relocate/aim camera and light, then record a different area inside the hull.

    Eventually you will find where the water is coming from.

    One common leak area is the hose fittings that pass through the transom plate, cause by poor transom plate to hull factory sealing.

    Lots of possible water sources.

    The bilge scavenge (aka siphon) can make it seem like no more water is coming in, when it may be that there is more water coming in but the additional is actually getting drawn out as you ride.

    as i use the Lucky13 Pump cone i removed the siphon... so the only way is something with the exhaust.... which would make sense....but i will use a camera an test...

    Every ski I ever own had a small. Amount of water in it.. Some times the transom isn't sealed well from the factory.

    Could be the way the ski is sitting in the trailer.. Make sure it's totally dry before going in the water.

    Remember there's a little bilge belly under the motor.

    put the drain plugs on and fill the ski inside with water 2 inches and see if you see it leak out since it will be cold and tilt the ski upward and you will see if its the transom keep us posted
