Default Lubricating Control Cables

Mine should probably be replaced. No time though and it looks to be a PIA job. Has anyone tried lubricating throttle and shift cables in lieu of buying new ones?? Thinking of using a motorcycle cable luber with WD40 or some kind of spray teflon lubricant. Whatya all think?

If the jacket is still good ... PB Blaster. What Ive done for cables is blow lubricant thru from one end to the other after the blaster did it's magic.

If you are talking about the hose with the valve stem and Marvel Mystery Oil that I found I say I am going to try this on my Silverton throttle cables.

Cables on boats in salt water often corrode under the plastic sheath. That happens where the sheath gets a cut or the like and salt mist does it's damage.
If the cables are just gummed up, a solvent and lubricant may help but getting a 20 foot cable lubed is a lot different than a three foot motorcycle cable.
FYI, WD-40 is not a lubricant. It is a penetrating solvent and dissolves a lot of things. Ofter it seems to work because it dissolves old gummed up grease and turns it into softer old grease

It does help to coat the exposed ends of control cables to reduce moisture penetration and corrosion but once the metal sheath or inner core start to corrode, it's time for new cables.

I think the house boat cable lube device is the trick here. When starting from helm, should I stop when seening MMO coming from opposite ends?

Yes, Then reattach and exercise the control lever. it's not so much of a case of purging old lube as getteing lube where there is dry friction. Many boaters have had good results using that homemade pressurized application system of "Old Houseboater". But note if the inner cable strands are parting and binding or the cable was crimped, results may be poor ... could eventually fail altogether.

For others, the description of the simple device & use can be found with a search for " Houseboat Control Cables-How to Lubricate, Or Save a Throttle ".

MMO apparently works OK, but Davis cable lube for steering cables may work better for longer.
