The boat is a 1991 four winns with an OMC 4.3 with a cobra drive. The remote control on it has a part missing that holds the lever on the assembly. It looks like to me that it might be some type of rubber boot or something. Makes it a pain the butt sometimes when moving the throttle because it will sometimes just barely side off. Would anyone know there to get this part from? Or am I stuck with get a new remote control?
