    97 Seadoo 787 xp Small water leak manifold

    My 97 xp 787 has developed a water leak at the rear lobe on the mag cylinder, not a whole lotof water is coming out. But still has me worried as this is a newly rebuilt motor. Can I pull pipe and use a rtv silicone?

    Will it hurt to run it like this?

    you don't want to use rtv..that almost assures a leak. Use high tack or copper gasket spray in those areas.

    Water leaks are not to be ignored they should be fixed, if they start leaking into the engine, it will be all over in a very short time.

    Proper surface prep and careful assembly will assure new motor installs do not leak.

    I fix lots of leaks started by shadetree guys,...when I see orange or black RTV on a PWC engine, I see $$$$ down the road as they will ALWAYS leak there.

    Get a mirror and check to see if you can spo the source..a little talcum powder in a bottle will help find it.
