My 06 fx 140 will fill up with water when left in the lake overnight on random times. What I mean is that is doesn't fill up every time I leave it in the water overnight. I got the boat out of the lake, filled it up to the top of the battery with water and it didn't leak out anywhere. So I don't think it is a hole or a seal. Is there somewhere it could be leaking in from the jet pump ? If it leaks during running then the bilge pumps it out, because it is always relatively dry after running it. It only does it after sitting overnight. Is there some sort of check vaulve somewhere that could be sticking?
Thanks
