No, that's like winding a paper towel roll around a wet and soggy tube! Use the old sheath to pull the new cable thru! 😁
Seems like that would only be a partial fix, and likely the problem would reoccur or escalate to something even worse.I suggest replacing both....but Im not the one depending in that part to get me home.
Why would you want to? They don't break for no reason. They break from rust intrusion and lack of lubrication which damages both the sheathing and the internals. Replace them and any other rusted moving parts of the shift mechanism. unless you have a good understanding of how the system works and how to properly set it up I recommend having a professional do it. There's a lot more that goes in it than simply shifting. There is usually an ignition kill for a slight moment depending on the brand of the engine it is not properly aligned you'll get nothing but a headache, with a boat that stalls every time you go from forward to reverse.
