With these items in hand, you can complete the cable replacement process quickly and safely. First remove the bottle insert from the motor bracket and disconnect the extension from the control box. Then identify and remove the old throttle cable from its mountings. Finally, install and secure the new throttle cable following all of its manufacturers instructions. After completing these steps and double-checking for accuracy, your Mercury outboard motor will be ready to go with a new tiller throttle cable!

Types of Throttle Cables

Mercury outboard tiller throttle cables are mechanical cables that are used to control the speed of the motor. These cables can be connected to the motor or directly to the tiller handle. The cables are often made from stainless steel or a combination of metal and plastic materials. Depending on the model, some Mercury outboard tiller throttle cables may be adjustable to accommodate different speeds and settings.

Tools Needed for Replacement

When replacing a Mercury outboard tiller throttle cable, you will need a few basic tools. This includes screwdrivers, an adjustable wrench, and possibly a socket set depending on the type of bracket that is attached to the motor. It is important to use the correct tools for this task as it can be dangerous if done incorrectly.

Removing the Old Cable

The first step in replacing a Mercury outboard tiller throttle cable is to loosen the bracket nuts which secure it in place. Once these nuts have been loosened, you can then detach the old cable from both ends, one from the motor and one from the handle. It is important to ensure that all connections are properly disengaged before removing any parts.

Installing New Cable Assembly

Once you have removed all old parts, you can then attach your new cable assembly onto both ends of your motor and handle respectively. Make sure that all connections are firmly secured with either nuts or bolts so that everything remains in place during operation. After this step has been completed, you can then proceed to secure your new cable bracket with nuts or bolts as well so that it remains secure during operation as well.

Troubleshooting

After installation has been completed and checked for proper noise output and other potential problems such as binding or snagging, it is important to test your new Mercury outboard tiller throttle cable for proper operation before taking it out on open waters. This last step should ensure that your new system runs smoothly and without any issues while out on open waters.

Testing for Carbon Deposits on Connectors

Before beginning the process of replacing the Mercury outboard tiller throttle cable, it is important to first test for carbon deposits on the connectors. This can be done by using a multimeter to measure the resistance of the connector. If there is any evidence of carbon deposits, they should be cleaned off with sandpaper. Additionally, it is important to apply a corrosion preventive coating to the connectors so that they do not corrode further.

Inspecting Terminals for Leaks and Damage

It is essential to inspect all terminals for any leakage or damage before starting replacement of the Mercury outboard tiller throttle cable. The rubber boots should be assessed for wear and tear, and if necessary, replaced with new seals. To ensure proper functioning of the throttle cable, all terminals should be free from any dirt or debris.

Cleaning of Coil Assembly’s Ports

The ports in the coil assembly must also be cleaned before continuing with the replacement process. This can be done by using compressed air to remove any dirt or debris that may have accumulated over time. It is also recommended to use a soft bristle brush to clean all coils in order to ensure that they are free from any obstructions that may interfere with their performance.

Adjusting Idling Tension Spring on Lever Arm

The last step in replacing the Mercury outboard tiller throttle cable is adjusting idling tension spring on lever arm. To do this, it is necessary to release the locknut which holds the idling spring in place and make adjustments as needed until desired performance is achieved. Once adjustment has been made, it is important to reinstall the lock nut before continuing with installation of new Mercury outboard tiller throttle cable.
