    Air Vent For The Back Of The Ski

    Anyone have a good idea for air vents out the back of the ski and look good?
    I need this for venting from catch can.
    Maybe one with a one-way check so water will not come in.
    What do the other guys use on the other skiís?

    Most run a breather on top of the catch-can.

    Flo Rites are usually used to allow air to flow through the hulls without letting water in. However they are not meant for direct water splashing.

    Vent is in the Front

    Here is my setup with catch can.
    Do I need to be concerned with fumes in the engine bay? This is in the back end of the ski. My air vents are in the front of the ski. My only concern is that at low speeds or idling round that I donít get to much build up of vapors in the hull?

    Nothing from the engine, crankcase, or fuel system should ever vent to the interior of the hull.

    Either vent to the hull exterior, or to the engine intake tract, where the engine will consume and combust the vapors.

    In the event of an engine problem, such as excess blowby, you could get a large volume of potentially flammable vapors from the vent, so vent with safety in mind.

    He's referring to his cooling catch can,which shouldn't have any explosive vapors from it,Just anti-freeze.
