    Are these hose suppose to be like this?

    Hey,

    I have not had time to read the entire manual yet, but decided to open up the engine seat. What are the purpose of these hoses that aren't connected to anything...?

    yes, they are supposed to be like that. I believe they help get fresh air into the hull since your air intake is inside the ski.

    Yes ventilation, gas fumes are heavier than the air and stay low in the hull so thats the reason they are strapped on the bottom, to get the fuses out incase you have a fuel or vapor leak

    ???? How?

    If the fumes from gas are heavier than air how will they go 'up' the hoses? There's certainly no vacuum or forced air involved.

    Usually there are connected to the outside of the hull where air passes by. This would create a vacuum which would pull air up through the hose thus sucking the fumes out from the bottom of the hull.

    If you're riding offshore with big waves a lot of water is coming over and into your ski through these air inlets.
    Air needs to go in so water will come in as well. With this design the water will enter low above the bottom.
    And air will go up from the bottom to the air inlet box / filter without any water.

    xewkija631 maybe it's an idea to start only one thread for all your questions "My new RXT-X"

    They also work to slow the amount of water that will flow into the hull if the ski is upside down....

    I would favour that's the only reason they're there. I have them on my aS and no air passes by the openings when riding as they're buried deep under the top moving deck, so there's zero venturi effect pulling anything out of the hull.

    But in an extended time roll over, they would definately buy you more air time.
