    Sponsons dripping salt water

    My XLT sponsons drip water for days after I ride and I get salt crystals around the sponson and on my garage floor. I pulled one off and there was still water inside after 6 weeks of being out of the water. Has anyone tried filling these up with sealant or bondo?

    I use GE Silicone

    I seal the sponsons to the hull to prevent just this problem. I also used to get seaweed stuck in there.

    Gipper do you just do it around the edge or fill the whole thing? I was thinking bondo but it is not recomended for below waterline use, then I thought fiberglass resin, but not sure about that either since it will be solid, no flexibility to seal tight to the hull.

    If sealed around the sponson with silicone and water did get around the sealant into the sponson it would not be able to get back out, that was my thought on filling them up with something.

    Thanks for the replies guys. If I come up with something I will let you all know.

    I just silicone the edge. I recently took them off to add Bullett sponsons and they were dry as a bone inside. Just be careful and seal them up well.

    I would fill the voids in them first, then apply a thin bead of silicone on the mating surface and allow it to dry off the ski. This would act like a seal and still be serviceable.
