    550sx stock bilge question

    On my 550sx Yamasaki i was taking in a lot of water. Turns out my surf jet Louie tubbies on the carb side de lamented from the bottom of the chine and it was scooping water into the hull. My 500gph rule takes care of it. I dont think my stock siphon bilge is working. I took it apart and the line from the pump is clear into the hull. The anti siphon hole is open.

    My question is: do i need to clamp the hoses on the engine side? There stock and its a 1990 hull. The hoses are soft and fit snugly but would a small air leak stop the siphon from working? Iím going to clamp them but out of curiosity Iíd figure Iíd ask.

    The stock siphon should get most of the water out. Itís not! Always have about a inch and a half of water in the hull. The siphon pickup is always under water.

    Any advise?

    Did you check to make sure the tube isn't plugged in the area it runs through the hull?

    The older I get, the more I find myself fixing things that I knew I was doing correctly at the time.

    Long live SJL!

    Agreed with above^
    They didn’t come clamped or secured from the factory.

    Not plugged. I re 5200íd the tubbies real good to get through the next month of riding. When i pulled the ski out of the shed before the build there was some 5200 hanging off and i pulled it out. About 3 inches. STUPID ME! Itís sealed back up now. Maybe the stock siphon couldnít keep up with the incoming water. 15 minute ripp and have 4 inches of water in there!. Hopefully its all good now and this winter ill pull the tubbies, foam them and re-install.
