sticky throttle controller

[paul1]

Hi , my left hand controller has become very stiff in acceleration, on disconnection from the engine the lever moves freely and smoothly, and the lever to the engine also moves freely and all the way to the stop, however all greased up and connected again, the problem persists, is the problem with the cable under strain?.
To add to the problem the securing screws to the control unit are spinning, so i have not been able to check out the inners of the control unit as yet.
Any suggestions please.

Cable corrosion of the core inside the outer sheath would be one possibility. I don't know if it particularly affects throttle cables on boats but it is certainly something that happens with all sorts of other similar cables. You might get away with lubricating it but if the inner core is corroded or wearing out (many of them have a sort of teflon coating on the inner core which eventually wears off) then it is only a matter of time before it breaks....

It could just be awkward cable routing but I have a similar problem with mine being very stiff (haven't investigated it yet) and I think I am going to change the cable to be on the safe side. Don't fancy being stuck at full throttle! No throttle in an awkward situation is not much better...
