Re: BRP control box/shifter
That is a friction adjustment so you don't have to have your hand on the control lever all the time. You should also not try to shift a boat without the engine running. If the clutch dogs are not lined up with the notches in the mating gear you cannot force it into gear. If you try, you can damage the control box or the cables. As for "messing" with things, you are advised NOT to do that -- at least until you have a reasonable idea of what that device is you are "messing" with and what the consequences are if you don't know what it is.
