    Default Bilge pumped fail or battery died = Moomba at bottem of the lake. Help us!!

    Hey all,

    New too the forum. Looking for some much needed advice.

    Last June my buddy and i were in Vegas got a call that are boat was sinking.





    Here is the 27 min video of the recovery of the boat: http://www.youtube.com/watch?v=3OrmgjJMHtI


    So we believe it was a bilge pump failure and combination of the battery dying.

    We just put a new transmission in it and we have it running. But now we want to be able to prevent it from ever having this problem again.


    So this is where we need help!!

    What is the best battery and bilge pump solution? We would like to leave the boat in the water up too two weeks at a time. Without the battery's dieing on us and the pumps stop working.

    Thanks in advance

    Wow - welcome to the forum and bum deal...

    Did you determine why the boat was taking on water in the first place?

    Boat looks like an older Boomerang but hard to tell for sure?
    Old enough to know better, young enough to do it anyway.

    So on flat land tonight we filled up the boat with water and it was dripping from the drive shaft. So not enough filler around it... We're assuming that's the reason why it sank.

    Good news all the speakers and bazookas still work!!!

    Was it moored without a cover during very heavy rain?

    It seems like it would take a lifetime for the prop shaft to left enough water in to sink the boat. When you tested it was it a steady stream of water? That doesn't seem right ether.

    get a lift.
    a bad shaft seal can sink a boat pretty fast. always check the seal before leaving the boat moored. It doesn't start leaking suddenly by itself just sitting there.
    If you believe something to be true, it will be - in it's consequences.

    doesn't take much water in those boomerangs to push a back corner under the water, and depending where it's moored, one wake/surf boat wave would do it in..

    agree with the lift option as that's almost failproof, but if it was mine, I'd ensure it has 2 batteries, one for starting and one for stereo isolated so they don't drain off each other and use 2 bilge pumps, one hard-wired to each battery. redundancy is the key..

    That was the word I thought of: redundancy. A second bilge pump, maybe on it's own battery, and that sits a little higher up so it comes on only when the other one is gone. A good cover would help a lot too. Won't keep all the water out but it sure helps if you can push 80-90% of the rain water over the sides.

    I'm not to for sure if it was raining. but we did have a cover on it. Apparently not good enough. it was over the engine when we pulled it up. We filled it up and it was pretty wet and starting to drip.

    Yeah im assuming it filled up and then the back corner had a wakeboard wave go over it and then the water just starts filling up fast after that. That was what we were thinking. Also getting a switch for battery 1. 2 and both.

    So in the boomerangs there is only 1 bilge hole. were going to drill a 2nd one and put a second bilge in there.
    It's hard finding a cover that fits because there is an after market tower on the boat.



    im at work so im typing this quickly. Thanks guys for the suggestions keep them coming. i'll post some more photos that I took last night when we were working on it.

    I keep getting this vision in my head of a couple douche bags in their Dad 's sacked out boat purposely sending rollers over the back of your boat and watching it fill with water.

    The Boomerang has such little freeboard and sits so low in the water that I don't think I'd leave it in the water unattended.

    Lift or trailer option , but extra battery and pump might help the leaks but not the waves. Won't pump fast enough. A good cover will deflect some.
