Lee, The solution Edson came up with to overcome the return spring on the throttle rack is to drill and tap a ¼”x20 hole in the engine control boss (on model 816 and 870 controllers) and install a set screw that bears down on the delrin sleeve that the throttle lever shaft rides through. This provides enough friction to keep the cable in place. I believe it became a standard item sometime in the mid nineties. In their instructions <http://www.edsonmarine.com/support/PDFs/installation/EB396EngineControlInstr.PDF> , it is referred to as a throttle friction adjuster. Morse 33 cables are not able to be lubricated. They have an inside Teflon jacket which allows the solid wire cable to move inside the cable assembly. If there were a means of lubing the cable, it would only tend to make your cable slip inside the jacket at ALL RPMs.
Because Half Magic, my 1983 LF35 has a model 727 engine control (with the two SS tubes that sit aft of the pedestal and engine controls up and down on either side of the pedestal), the builder or PO installed an external cable clamp outside the cable below deck where the clamp could actually crimp down on the cable jacket creating friction. Seems to work so far, but I’m sure it isn’t the best overall for cable longevity. I’ll try to dig up a photo of it next time I’m on the boat.

It falls right after I let go. I can set it higher when moving it at the engine, but not at the helm. How does one adjust the cable on a 1985 C&C 33-2? Or is there a way to oil the cable? PO used a bungee cord to hold it at higher RPM. Thanks, Lee Kookaburra 1985 33-2 Kenosha, WI
