    Default Mondo water in bilge

    Each time we surf water fills the bilge to about 1 to 2" and the bilge pump kicks in every so often.

    Is this normal? None of the bags appear to be leaking. Just wondering what I should check for if this isn't normal.

    When we just cruise around there is no water.


    Thanks

    What year Mondo? I think some people cracked their tanks when adding a bow bag. This could be your problem

    I had a hole in a hose behind a finish panel that caused this on my Craz.

    If boat is off and your not filling bags and the bilge empty’s the water does it fill back up again?

    May not be the issue at all but I get water in through the rear vents on the Max when I stop moving, putting water in the bilge only when I surf.

    Check the prop shaft seal while someone is driving. May still be leaking while underway but just not as bad at lower rpm.

    I have a 2016 Mondo with they bow bags from factory.

    I have a feeling it's either the back vents or one of the ballast hoses are leaking.

    I'll fill up the ballast and watch where the water is coming from
