Flex Shaft Lubricants

Amsoil blue marine grease on my flex cables

Where do you get that from?

I got mine locally at a small marine shop in Dana Point, CA. Check around, West Marine may carry it, but you have lots of places in SD that should carry it. Runs about $9 a tube and a tube lasts a very long time.

I owe an apology to everyone expecting results from the lubricants comparison.

I was only able to complete 2 runs before I hit an unidentified submerged object (USO). I sheared off the nylon bolts in both the rudder and turn fin. This also caused the stripped motor mount bolt to come out. I also slightly damaged the prop.

After all that I decided that the water in the lake was receding too rapidly as 'new' USO's (mostly tree stumps) were becoming noticeable, so I stopped the testing.

I will give it another go when the water rises...

What about brake caliper grease? High temp stuff for the shaft, lots of heat there. And I'm kinda amused by clever marketing from marine companies when they say "waterproof" grease. Water and oil have never mixed.

Never tried brake caliper grease. But if it works go for it. As far as water proof, I seen some greases emulsify on flex shafts.

I have never tried caliper grease either. I have used it on brakes and thought about it on the boats. I use just whatever marine grease I found. To me I regrease after I run. Unless I'm going right back out. As far as the emulsifying within the shaft yes some less weight greases tend to mix rather quickly. Just thought it is ironic about waterproof grease. Just being funny:)

There is nothing wrong with emulsions, they can provide excellent lubrication properties. I use them in my work spinning 5" shafts in 8.5" holes 20,000 feet long. Most all R/C boat cable lubes will emulsify in water anyway, "waterproof" or not.

I've been using white lithium grease on my impulse31 and the kids 26 stock proboats, is this not good ?

I use it on my centre pin reels and it makes them spin like mad ! and goes good with water !

small tube is cheap at my local hardware store > $1.99

Sounds like a myth busters experiment

Wow, someone is actually commenting on a 3 year old thread... I’ve been on the nitro side of things for a while, but starting to run my electrics again.

FWIW, I did perform the lube tests, but refrained from publicizing my results due to the ‘uncontrollable variances’. I felt that the results would only start a ‘flame fest’ like the ‘water removing heat’ thread.

I will say that there is some speed to be gained, but it came at the cost of longevity. The marine variants remained the longest while the Cera Grease allowed for the best speed. Every one of them emulsified (it’s not a sealed environment). In the case of the marine variants, the second and/or third run produced the best speed. I can only guess that this is partly due to their water resistant adhesion that broke down slower.

I ended up liking Lubriplate for its ease of application. Just hold the prop and spray it on.

Yes, just me, I actually read things new and old :)

No problem Coop... Just surprised that's all...then again, I'm surprised a lot these days...must be that 'old-timers' setting in...

Lol old timers! I must be a middle timer!

Did you ever test ProBoats Grease?
