Is there a fixture or tool that can inject a lubricant into a trim indicator cable? I have three cables for the drive angles that are getting sluggish when trimming past level flight. I'd rather not replace them on a 43' boat as the jackets are in perfect condition with no binding or kinks.

Thanks!!!

Do a youtube search on "lubricating cable". There are a bunch of videos out there for motorcycle throttle and clutch cables and the like. Some folks have had luck using the WD-40 in a ziplock bag method. Use gravity as your friend.

Are you sure its the cables and not the springs or plungers on the drives???
The plunger springs can get contaminated with sand and grit and make them hang up.

I don't know the brand but i bought a tool years ago to lube bulkhead style cables. It's a tube maybe 10" long and it's threaded on the inside. Pull the dust boot off and screw tube onto bulkhead. I made a reservoir out of pipe fittings and fill it with something thin like air tool oil and pressure it up with shop air. It can be a little messy where it screws on but usually it will push oil clear through. It don't work every time but have bough some time before having to replace.

If the cables are hanging up and it's not the plungers they are done and need to be replaced. Lubricant doesn't really help much. The cable has worn through the inner jacket.

I will take apart the plungers tomorrow as well as make a pressurized tube to clean the cables. I saw several videos, all with the same Teleflex Morse cables and even though they are teflon jacketed and supposedly self lubricated, they tend to wick up water which causes the lining to swell over time. The method I will use is a clear 3/8" tubing with a valve and pressure connection to push Marvel Mystery Oil into the cable after flushing them with liquid WD-40. I plan to make a video on this procedure and we'll see if it helps my indicators read properly.

Cable could be starting to fray inside which happens a lot , if that's the case no wd-40 or Marvel will work
