Default Lift cable maintenance

What is recommended for maintaining the cables on a lift located on a saltwater canal?

TIA for any constructive suggestions.

I do the following:

Lube all zerk fittings every 6 months.
Wipe down cables and rollers with CorrosionX HD from time to time...
If I don't have CorrosionX HD I'll use BoeShield.

IMHO the cables are the easiest part to keep nice. The part that has me a little miffed is that the actual aluminum beams that go in the water (where the bunks are) aren't as pretty as I would like them to be after less than a year.

I also spray the motor, etc. with BoeShield.

I use a rag for the cables.

Thanks Pete.

Yes, I agree that the cables are the easiest part of the system to deal with and that the beams the boat rest on show what I guess is corrosion surprisingly fast. I don't know that it really made any difference but if the boat is going to be off the lift for more than just an hour or so I never leave the lift in the water while I'm gone on the boat. I did see an episode of Ship Shape TV where he applied Shark Hide (I think that's what it was) to his lift beams to prevent this. Of course I don't know that it does in fact hold up over the long haul but that was, of course, the assertion they made in that segment of the show.

Anyway - thanks for the input. I already have some Boeshield so I'll just use that for now.

NAPA sells a cable lube that they use for maintenance on heavy equipment. Anyone used that? Seems it might penetrate deeper into the strands, which is where the wear occurs.

Just curios, what kind of lifts do you own that show the bottoms beams corroding over a short time?

Thanks

Mine is a Golden Boat lift installed by Stokes Marine in June 2016. Corrosion may not be the best word for what I'm seeing but not sure what would be a better description. Pitting maybe? It's not rust as one would see with steel beams but it is a surface oxidation issue of some sort.

Aluminum oxidation?

Aluminum does oxidize however that may not be what is happening here -- it's just the best way I could think of to describe it. This is just a random picture I found on the web associated with aluminum oxidation but the white spots you see here are basically the same thing I'm seeing on my lift - just not that severe - yet.

Do you leave the lift in the water while you're boating? I had a remote and raised it back out of the water. You may have some electrolysis. Docks often have rogue current in the water. As well, I rinsed it as I cleaned the boat. Spray lube to soak the cables monthly. Maybe over kill, but it feeds my OCD!!

Nope. I always use my remote to raise it out of the water. I am amazed at how many of our neighbors do not do this even though they have remotes.

My lift manufacturer gave me a spray can of a heavy duty spray "chain and cable" lubricant. It feels more-or-less like a heavy grease in a solvent base. It does soak in remarkably well to the stainless cable - I assume its primary job is to prevent corrosion of the strands, especially where you might not see it. I generally try to clean/lube everything on the lift 2x a year although I know many go years with zero maintenance.

I leave the lift in the water unless I think I'll be away from the dock for more than 12 hours, but I'm pretty brackish water.

Aluminum oxidation is pretty normal, try finding a saltwater trailer that looks new after a year. Severe pitting is what you want to avoid. Lots of products you /could/ put on your beams to slow it but that is a fair bit of work for minimal benefit.

Don't forget your zincs.

A lot of the bunk corrosion is caused by stray electrical current in the water.


Could be from your lift or dock power or one a half mile away


Usual culprit is improper grounding
