    Default tire spin update

    Here is a video when I take off. You can hear I have to feather the throttle some to keep from getting that tire spin feel. Is there anything you notice on take off that could help. I smoothed out the intake. Replaced o-ring on the clean out and changed the packings on the shaft. I have the ride plate adjusted to even with the keel. I am only running a rock grate, no loader.
    I still have a little tire spin fel if I don't feather the throttle on take off.

    Thanks
    Brian

    This is the link right to the video-

    If you have a worn out wear ring, you may be experiencing blow by.
    Believe Nothing you hear and 1/2 of what you see.

    At take off your jet needs to be lower. Drop that thing all the way down, roll on the gas, then bring it up as you get going. You're gonna have to feel it.

    That pump most likely has some clearances issues with wear ring and impeller , When it cavitates on take off that's the symptom of a loose pump

    won't make one ounce of difference from what I saw in the video.

    I have to disagree with you BP. The OP will see at least 2 ounces of difference

    I know there are other issues there

    if at the hit, the bow was rising to the degree the intake was uncovered at all, it would make a difference. i'm not seeing that. boat is still buried when he's pedaling the thing. pump needs some work, as well as an inducer.
