    New 300 X with small water leak right out of the crate from Kawasaki

    Dealer did water hose test and no leak. I put in water and idled for 5 minutes like break in says and hull had roughly 32ounces of water in bottom. Drove ski 7 miles had only 16 ounces in hull. Siphon working here. Took home and dried hull and did hose flush for 15 min and no leak like dealer did. Went back to water and idle and 30 mph leak is back. Back home I snug all hose clamps. Leak is still there. Water in hull is gulf temp. Appears not to be exhaust leak Took to dealer and they water tested it with seats off looking for spray. None. Left on trailer in water for more thorough look and no help there. They are calling Kawasaki mon morning to see what Kawasaki has to say.
    So does anybody want to chime in with a fix? Has this happened to anybody else
    Oil looks good, engine is running strong just have this water leak. Also let ski sit in water with engine off and no water.

    Have dealer test the ski on the trailer backed into water with the engine running, just the rear half of the ski and the ski still tied down tight as you would traiker. Remove the seats and the plastic rear seat tray and look inside where the leak might be coming. Vary the rpm and that might spike the leak rate.

    they did that already. everytime we check for spray there is no spray anywhere and no evidence on parts of any kind.

    You can try filling the hull with water while the boat is on the trailer (a reasonable amount of course don't drown the mechanicals) and see if any leaks are evident.

    I had to ask, nothing against you. Have you tried flushing the intercooler? that is on a separate flush port and if you were just running it on the hose it could have not pressured those hoses.
