    This sounds like transom seal, it can pull apart more under load.

    Possibly the same and transom plate needs resealed. Remove intake grate and ride plate and experiment again to better see where water coming from. I think I recall the ride plate mounting brackets failing sometimes on that model cracking and being a cause of leaks as well.

    I filled my new FZ with water as its getting some inside when riding too.. and leaking from same spot.

    I plan to pull transom, and reseal with black 4200 did that on my last FZ and fixed a leak. ALso wile apart will fill vouids in the transom plate with resin.

    Hi .
    Thank you very much for your answers........
    I'm going to go disassembled parts and so I'm going to check the bilge water of the jet ski.
    I have also thought about installing a bilge pump.
    It is cheap .
    Since water never enters, I think it is an impossible mission.
    Thank you.

    That's for the fast cure 5200, the regular 5200 takes much longer to cure, several days
