    rattling sound on GTi

    After trailering my 2002 GTi I started it just to spit out any water that may have been stuck in the engine. While idling there was a loud rattling sound that came from the boat. I couldn't tell if it came from the back end or from the engine compartment but when I reved it up just a little bit the rattle went away and everything sounded great.
    What could be that rattle? Do I need to worry about it?

    Is this a new sound, or is the boat new to you?

    There is often a kind of rattle sound from the pump when it is on the trailer. If the sound is new, or different from before it may indicate a problem in the pump or with carbon seal.

    I got the boat a few months ago and have used it this year maybe a dozen times so yes I guess that's considered new to me but I think it has done it ever since I got the boat.
    Is this a bad sound or is it sort of normal?

    It is hard to say as I can not hear it but some noise is normal.

    I have an o4 GTX that does the same thing. No problems. My brother-in-law has an 01 GTX that does the same thing, no problems.

    i've found that the rattle is normal but if you get a buzzing or vibration it could be the bearings in the pump, or at least its been that for the ones I have done

    I have a 98 GTX Limmited that makes a Rattle sound in the Water if the idel is below 1400 rpm. Sounds almost like a knock but just a slight rpm increase and it goes away. Ski performs well otherwise and will run 6860 rpm at WOT. I have owned this ski for two summers and it has always done this. I have greased flywheel as discribed in the forum. Should I look for something or is it ok. Any advice appreciated. Thanks
