i have livorsi controls that look as though they came stock with the boat but don't know for sure . anyway was driving pretty hard this weekend in some rough stuff and the round machined pin that holds the throttle cable to the throttle lever fell out . WTF was not really happy about that ,can somone tell me what secures or holds that pin in there so that it does not fall out . i do not see any kind of lock pin or screw is there supposed to be one ? could use some info thanks .

Those might be the Morse controls you have there...
