Throttle control cable
 
I just replaced my throttle control cable - this after an interesting landing in which my throttle came loose in my hands as I was about to turn off the fairway and into my dock. The old cable had seized and the screw attaching the throttle handle sheared. Thank Vice GripsŪ for a quick and effective solution!

Anyway, my new control cable runs too smoothly (from one extreme to another). It doesn't 'stick' at a setting. When released the throttle backs off to just above idle.

Are there any suggestions as to how to increase the resistance in the cable? I was told that this will happen over time and, for the time being tie off the throttle at the desire setting with a bungee etc. I can see this working, but I was hoping for a more permanent solution.

Thanks in advance.

At one end of the cable, cut and slit a piece rubber hose that just fits over the fixed part of the sheath, and overlaps the sliding part. Tightly clamp it to the sheath with a tiny hose clamp, put another over the sliding end and add just enough friction to stop the creep.

I see cable clamps used often, I have two on my new throttle cable

Here is a cable clamp in use - worked very well.

I had the same problem early last year. As recommended, I installed a Morse Teleflex throttle cable brake. It is a little on the pricey side for what it is ($22). Also I realize that the set screw within the Edson pedestal broke off and was not working right. This set screw also does the same thing. I tapped a new bolt and together with the cable brake clamp, works very well. I have heard of people reworking the internal throttle spring (Yanmar). This is something you want to avoid. If your throttle cable broke, there would be no safety measure of bringing the engine back to idle.

I like Faster's idea on using a larger hose and hose clamp, as long as the hose clamp is strong enough. When you tighten the throttle cable brake, you can hear and see it really compressing within the shield of the cable at one pin point location. With the hose clamp concept, you would have two locations and you would have the hose to soften the load onto the clamp.
But as with the other bolts you would be using, either throttle brake or set screws, you will want to use Loctite on the threads. Not the strong level sealant.

Anyways, easy fix and a couple of options.
good luck.
