    4 tec 215hp cooling hose is being squeezed when hitting the trottle

    I did buy a seadoo speedster 150 with the 215hp supercharged engine, and got it out for the first time this day, and when i got home, i started the engine to blow out the water
    from the exhaust, and saw the cooling hose being squeezed together when i hit full throttle so is that normal?

    why were you reving it to full throttle out of the water? you just need to blip the throttle.

    the hoses move a little but should not be "squeezed" together. i think your being paranoid about your new purchase. just enjoy it and when it breaks it will tell you.

    I can understand that things move here and there, but i never saw a cooling hose being squeezed. I'm new to 4tec engines, because this is the first i own,
    so i don't know what's normal and what's not.

    I'm not very familiar with those boats but I assume they have an open cooling system, if the tube were filled with water it wouldn't compress.

    Conplete guess though

    Tip....Take that air filter & throw it in the garbage.

    The screen part rusts & now goes thru the motor. Get a K&N

    There's no problem with reving it once or twice when it's out of the water, because its a standard procedure
    to blow out the remaining water from the exhaust before you store the ski or boat.

    only the exhaust is cooled with water from the lake or sea, but the engine itself has a closed system that is cooled by the ride plate that is hollow and acts as a radiator.
