Outboard motors are motors that are mounted onto the transom (or rear) of a boat. The gas-powered motor sends power to the motor's drive shaft, which spins the outboard's propeller. This motion is what propels the boat forward through the water. A throttle control cable is used to control the speed of the engine. If the throttle on the outboard begins to act up or not work at all, it's likely the control cable needs to be replaced.
Shift the outboard motor's control handle to the neutral position.
Slip one end of the throttle cable through the throttle arm at the bottom of the throttle lever. Tighten it down by turning the retaining lock nut with a wrench to hold the cable in place.
Shift the control handle from neutral to forward. Then shift half the distance back to neutral. Move the motor throttle lever so that the stop screw sits flush against the stop.
Connect the cable's casing to the two holes at the bottom of the throttle lever. Slide the lever's pin and insert a cotter pin through the slot and bend the pin down with a pair of pliers.
Slide the other end of the throttle cable into the hole on the throttle arm of the carburetor. Slip the fastening screw into the throttle arm hole and tighten it with screwdriver to hold the cable in place.
