Throttle Cable

[Bob Fuller]

The throttle cable has a tendency to back down at higher RPMs and will not hold its position. Any recommendations on how to cure this?

Look in the Photo Forum

Bob:Look in the photo forum and search for (An end to throttle creep). I posted an article in there. This is a 'J' clamp that will put friction on the cable. These clamps are specfically made for Morse cable and were recommended to me by my Yanmar dealer.

Throttle Vibration/Wondering Reduces Speed

I have the same problem with my Legend 37. I called Edson and ended up speaking with the president. If you have an Edson Pedestal he said that I should remove the compass and there is a screw above the throttle lever that could be tighten. The service guy at Edson told me to put a wire clamp on the throttle cable closest to the engine. The clamp is a "U" shape piece of round metal with screw threads on each end and a straight metal piece with holes at each end so that the ends of the "U" shape piece can go through the straight metal piece and then tighten with nuts. I hope this explains what the wire clamp I am talking about is.Tightening the wire clamp until there is some resistance on the cable. You need two people for this project. One at the throttle and one tightening the wire clamp. I tried this and it seemed to work.What I found after that was my throttle was extremely hard to move. To the point that I had to use considerable force to move the throttle. I thought that I tightened the clamp to far and actually crimped the cable. Last week wasn't a good sailing week so I decided to trace the problem and determined if I really needed to replace the cable.The long and short of it was that the cable was fine. The throttle on the engine was extremely hard to move. I had to use Vice Grips to move it. Apparently salt water somehow driped on the engine throttle and the salt cloged the shaft which caused the lever to freeze.WD-40 and elbo grease working the throttle back and forth for 10 minutes freed up the throttle so that I could easily work it by hand.I will be going out this Sunday and if the cable wonders again I will try the cable clamp. I will report back on monday.

Strong spring on throttle

I had a similar situation where water dripped on the throttle lever on the engine and caused quite a bit of rust, gumming up the works. However, even with all the rust removed and everything working normal, the basic problem is that the spring used inside of the governor mechanism of the engine is very strong, and when you adjust the throttle lever on the ped guard for more throttle you have to work against this stron g spring. Try removing the cable on the engine and then move the lever on the engin..you will see it takes quite an effort. For this reason I do not like the idea of friction on the cable with a clamp, as is normally done. I plan to try installing another spring that would aid the the throttle lever action on the ped guard and reduce the amount of effort required to overcome the spring tension inside the governor.Sure would like to hear if anyone has tried this.Ernie
