Thread: Champion V-drive rattles?

    My Champion V-drive rattles when I am just in gear at no wake speed. Never noticed until I put my drive line back in after getting a U-joint repaired. Took off the seat to make sure I have no vibration and U-Joint is looking straight and hear the rattling. Smooths out as soon as I give it any throttle.
    Bad news?

    A little rattle from gear lash is not unusual at idle. I can't imagine why it would change though from chaning a ujoint unless you lowered your idle speed.

    The split-case Casale in my old boat used to rattle at no-wake speed all the time, but the Champion in my Campbell seems pretty quiet. Then again, its hidden under floorboards so maybe I just can't hear it. If you're concerned, JD Machine in Lake Havasu specializes in these things, and they will rebuild it for about $200.

    Like Mike posted earlier, did you lower the idle speed or make any other changes since you last ran the boat? My Casale used to rattle at idle speeds until I changed props. My new prop loaded the gearbox so the backlash couldn't clack. Clacking in the no-wake zones shouldn't hurt anything.
    I don't think that this should be a problem since you stated that it goes away once you give it a little gas. :rollside:

    A rattle or light knocking noise at idle speeds is fairly common with a 'v'drive. The lower your engine idles the more likely it is to do it. It normally is caused by the drive gears bouncing back and forth against each other across the clearances or backlash...........

    Thanks everyone, the rattle was probably there all along and only noticed when I took the seat off to have a look at the u-joint turning.

    Damn Slyder you sound like you've been around boats a time or two. Ever been to a race or though about helping out on a crew?
