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

[TexasJaeger]

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?

There are two tension screws one on each side of the throttle, you have to unscrew and lift up the first cover to access them. You might have to make a couple adjustments to get them right.
