Marine grease question

[VR6 BeelzeDub]

I remember reading that people use marine grease when building their kits if they plan on running in water/mud...

Just got a new gmade GS02 and was planning on replacing the supplied grease with marine grease. Are there any areas that I shouldn’t use this? I.e. transmission?

It should be fine on any of your gears ie tranny, transfer, axles.

I appreciate the way that even after bombing around in the creek, there is still a good layer on the bull and pinion, and inside the tranny, if I were to look.

Also, get in the habit of oiling the moving parts of the undercarriage with 3in1 or similar, to prevent rust and make things slippery and quiet. Especially the U-Joints. Even a drop on the motor commutator is good. Splashing will remove most of it, so reapply, reapply. Only takes a minute.

Do not oil the plastic drive shafts.

Cheers...

ps: Colour doesn't matter. There are no grease industry standards vis a vis red, blue, green etc.

Just "Use liberally"? or "pack the pumpkin"? I've heard both. Seems a full crankcase would cause a lot of drag. Which is the recommended method?

I make sure the any engagement surfaces (ie gear teeth in a non locked diff) are completely full, as well as there being a good coating on any area that might contact the diff case itself under a hard bounce. Running RC rally cars, I've never had an issue, and never had a slow down from it. I don't know anyone who packs the whole thing full.

Way too many people do that then pretend they don't need to do maintenance because marine grease.

@Hobbyjumper - Didn't think of oiling the moving parts of the undercarriage with 3in1... Thanks

Any area that might contact the diff in case of a hard bounce? Drive shafts?

Thanks again for all the good info/suggestions!

I use this:



I would not use axle bearing grease as it's too thick and firm. This outboard motor grease is nearly liquid state, thinner than vaseline.
Free-running and waterproof. Goes in all my diffs and gearboxes.

I don't pack mine full. I think it's a stupid and wasteful practice. But I don't do maintenance because lazy!

Just mainly the edges of the gears. In a rally car you don't have near the suspension, and it's very possible to have a lot of violent chassis slapper landings (depending on the course and your driving style). Some manufactures make diff case's that are very, very tight, and any play that's built up can result in the drive pinion or ring gears whacking the interior of the diff case if you really blow a landing. I actually took a scallop of plastic out of the case (and we can guess what happened after that) one time from a very badly taken jump, along with a fully pinned throttle. I also almost blew the diff case off the body pan (IFS and IRS in that car), so that might have had something to do with it too. Better greasing probably wouldn't have helped, but it makes me feel better lol.

I use grim racer speed grease. It’s waterproof, thick and sticks. If anything I have had to make sure my diff gears don’t have slop because this grease seems unique in its ability to cause ring and pinion slipping. Check it here

Lucas Oil blue waterproof marine grease. I do a tear down after every run in water and mud. Dry trail run gets a tear down every third time out unless something goes Tango Uniform.
