How to Adjust Boat Throttle Controls

Boat throttle controls operate via steel cable, encased in a flexible steel sheath. The throttle cable is attached to the throttle handle by a shackle and to the carburetor's throttle by a throttle lever. When you need to adjust the throttle, you must adjust the cable. The first adjustment is at the throttle handle; the cable is then adjusted at the carburetor, to ensure that the cable is tight between those two points and securely attached to both.

      Fit the small shackle around the end of the throttle lever. Push the clevis pin of the shackle through the bore on the side of the shackle and the end of the throttle lever. Thread the pin into the threaded side of the shackle and tighten it securely.
