    Bucket won't lock going forward - Seadoo Challenger 210 SE

    Loose throttle on 1997 Challenger; How do I tighten it up?

    The throttle handle on my boat is loose. Meaning I have to constantly have my hand on it when I have it on low to medium throttle. Otherwise, it "falls" back down to idle. Anyone know how to tighten it up so that it won't do this?
