Boat Throttle Cable Problems [Handy Solutions You Need]


Sea brings peace to a lot of us. We feel calm and we can see clearly. Sea is the beauty of mysterious nature. This is why we get your passion for boat riding. However, if the boat does not work, this could be a serious problem. And to be prepared with solutions, you must have to get to the problems first. 

So, what are the boat throttle cable problems and how to resolve them? 

Boat throttle cable problems are sudden loose cables, adjusting issues, damaged cables and slow speed. You have to detect the problems first. In the case of sticky cables, you have to lubricate them as early as possible. Furthermore, you need to calmly adjust the cables which help in tightening. 

Wait, don’t leave. This is just a short overview. We have made an entire discussion about it for you. That will help you to know more about the problems. Stay with us and learn more!

How Does a Boat Throttle Work?  

The throttle control is the unit that regulates the level of the throttle or the speed. It is a lever you can press forward to boost the speed of the boat. When you’ve pushed forward the throttle, the engine throttle is opened in the outboard direction. 

This means more air and fuel into the combustion chamber at a faster percentage of frequency. If there is less fuel, you may encounter fuel pump issues with your Yamaha outboard

Consequently, this causes the engine to power greater, causing the propellers to spin faster. Outboard motors have their own throttle control and shifter on conventional throttle control and shifter. 

Because you can move the levers individually. When one motor is pressed forward or “throttled up” the other outboards do not.

So, you know how a boat throttle works. Now let’s get to the problems it can have. 

What are the Throttle Cable Problems? 

Boat throttle cables can have issues that can stop them from running smoothly. Such as;

  • Not picking up speed in forward. 
  • Adjustment issues.
  • The throttle cable can stick. 
  • The cable can be damaged. 

So these are the boat throttle cable problems. You can also have issues Now, let’s get to our next segment.


If the problem is with the cable, you can fix it. However, in case of severe problems with the throttle, you have to change your Evinrude controls. Here we have mentioned the problems and solutions for them. So, here are a few handy solutions that you can go for.

1. Not Picking Up Speed in Forwarding

Raise the engine cover first. Then look for the end of the cable. It will connect to the throttle body. You will find a brass barrel with a sliding back piece attached to a pivot ball. 

Then, disconnect it and advance the throttle meanwhile keeping an eye on the cable for movement.  If you don’t have any movement, then the cable may be broken. Or the throttle end connection is poor. 

If the cable is broken, then reinstall a new cable immediately. 

Adjusting Issues

For this, you have to tighten the cables. For this, you will need a wrench, pliers and a screwdriver. Follow these steps to tighten your cables. 

Step-1: Examine the Sheath And Throttle Cable

First, examine the throttle cable and sheath. So that it’ll be easy for you to ensure that they are properly secured along their entire length.

The cable’s sloppiness might be caused by the sheath becoming loose, reducing the cable’s travel. If necessary, re-anchor the cable and sheath in their proper locations.

To separate the throttle wire from the throttle, use a screwdriver, pliers, or a wrench. It mainly depends on the connection types. Then, adjust the throttle to the neutral setting.

Step-2: Move the Cable

Now. bring the throttle cable to the throttle’s attachment point. Next, move the cable until it is perfectly aligned with the points of attachment.

Step-3: Connect the Cable

It is time to connect the cable to the connection point on the throttle linkage. Make sure to do it without shifting the throttle. Depending on your boat, the type of connection will differ.

2, Throttle Cable Might Stick 

Firstly, fill the bag with enough engine oil to completely submerge the cable jacket’s end. Then zip it properly. Next, place a bucket below the cable’s bottom end.

It will capture the oil that will ultimately leak out of the jacket’s lower end. Lastly, leave the cable to hang until all of the oil has been drained.

3. Cable Can Be Damaged 

There are no tricks or other solutions for a damaged cable. You have to replace it without question.  But you are lucky if the damage is only to the cables. It will be a bigger problem encountering issues with the voltage regulator of mercury. 

So, these are the solutions to your boat throttle cables problems. However, this article cannot be over without suggesting you the best throttle cables. We have a few suggestions. 


Well, these will work great for you as it is one of the best. You can enjoy the sea to your fullest without tension. You are waiting for what? Go get it!


Are all Mercury Outboard Controls the Same?

They are almost the same. It all mainly depends on how much cash you have on offer. Your engine should be backward compatible with the new Gen 2 hardware. The Teleflex Xtreme cables are preferable over the Mercury standard cables. However, they are generally more expensive.

Why Do Some Bottles Have Two Throttle Cables? 

Because they make boat handling simple. Double mechanical controls are now the most prevalent type of control in use today. A single lever controls both the shift and the throttle in a fairly intuitive manner. Shifting is rapid and limited to low rpm, protecting the motor’s shift mechanism.

How Do You Rev a Boat in Neutral?

For revving a boat, when you shift to the neutral position, you’ll notice a detent. Which is in the middle of the shifter range. It has an in gear release button. The user can boost the throttle without moving into gear by pushing the release button. It allows the engine to rev in neutral. 

Wrapping It Up 

Finally, we have come to the end of the discussion. We hope this discussion has been helpful to you. Here, the main problem is loosening, getting stuck, being damaged, and not speeding up. These are the main boat throttle cable problems that you need to work on.

Good luck friend!
