    mystery hoses on 05 STX 12f

    I am in the final stages of bringing an 05 STX 12f back to life. One mystery I have, though, are two relatively large black hoses that I have in the front bin. They are about 3" in diameter. In other skis I have seen these used for fresh air... although I cannot figure out where they go. Any advice or suggestion as to their function is appreciated.
    PS - I think I have attached a picture of them...

    These hoses duct the air coming into the bilge to the bottom of the hull. In the event of a capsizing event, this will prevent water from flooding the bilge. There are two large holes in the rear grab rail assembly that these mount to.
