What grease if "Marine" or some specific manufacturers own brand is not available?

Lubriplate 130AA is recommended by MaxProp and is one of the most water resistant petroleum based greases around. In my experience only some of the silicone greases are more resistant to washing away.

Whenever I service my props with Lubriplate 130AA I am amazed that a lot of the grease from the previous service is still in there. After 12 - 18 months operation in the water, even across seasons where we are cruising in low wind areas and motor a lot. The stuff doesn't wash out from inside a feathering prop. That is about a good a recommendation as I can think of for a grease that is going to stay where you put it.

Thanks. Not what I have of course. "Super Lube" is a silicone based PTFE added grease. Edson recommends it for their steering cables. I have an autostream (similar to a maxprop) that needs annual greasing.

Lubriplate 130AA is a "Calcium" base grease, and is what MaxProp recommends. I have a big tube of Superlube synthetic grease which is used for greasing our cable-in-sheath steering system (works great!), so last year I packed our MaxProp with it - BAD MOVE.

We launched in May, and the prop had completely washed out by August, something that had never happened with the 130AA in previous years. I've gone back to a separate tube of 130AA for the prop!
If you are wondering, when a MaxProp has the grease wash out, it won't feather properly, tends to make loud clunks when changing directions and will vibrate badly at times because a blade doesn't fully seat - NOT recommended!

Good to know. Autostream says any lithium grease works for them. I've always used 24C Mercury so may just go buy some. It's worked fine over the years.

Since the subject is not political or controversial, Wikipedia is actually a good source for info about lubricating greases Check out: https://en.wikipedia.org/wiki/Grease_%28lubricant%29

In their manuals MaxProp very specifically says to NOT use Teflon (ptfe) based grease in their props because it will quickly washout. You have shown they do know what they are talking about!

[Hartleyg]

Oh, yeah - I read the MaxProp manual AFTER we hauled out & I found the greaseless prop! Live & learn!

A lot of automotive products can be used in marine applications.

In Canada, I use Permatex multipurpose synthetic grease on winches and Edson pedestal.

Permatex also makes sealers and adhesives for auto glass applications that operate in an environment just as harsh as offshore.

Technical Data Sheets are good indicators if the products are similar.

Thanks! Just picked up a tube for my new Propeller!!

Good to hear it works!! And that duration is not too shabby either...

So, they don’t sell Lubriplate 130 AA in cartridges for grease guns?

Also, be aware that there are certain applications that require water soluble greases. For example the grease for our shaft log states specifically that only water soluble grease is acceptable.
