I use the grim grease. I love it...

I use THIS stuff, when I remember to bring it to the races...

It's simply awesome

Your going to get a bunch of good answers on what is the best grease. And maybe you dont need a grease either. Keep in mind the viscosity. The thicker the grease the more friction it creates. Some folks have moved to oiling systems. Those work well too.

My favorite flex lube is a mixture of Mobil-1 synthetic marine grease and thinned down with Militec-1 oil. I like it with a syrup like consistency. Sticks, but is thinner then grease. What its going to come down to is maybe a little experimentation to see what you prefer. I dont think there is one all encompassing correct grease that stands out. So you might just want to pick one and stay with it for reliabilty. A 16 oz tube of Mobil-1 marine grease is a decades worth of FE boating. Its $10 at an autoparts store. Amsoil marine grease is like $16. Royal Blue marine grease is about $14. Then theres guys who like chain saw bar oil. That stuff works well.


Like I said. Its about what you find works best with your setups.

I've been using the Grim grease since it came out and love the stuff. I'm just about out of my supply, so I tried some of the ProBoat grease, and it works fantastically as well, and has a nice applicator for it.

I don't think you can go wrong with either one...

Many thanks, I was looking at the speed grease but ill also get the Proboat grease as well & try both.

[SweetZ28]

never tried the proboat grease but the tube looks alot like super lubs grease tube but white?
Is the proboat grease like a clearish white looking?

I have some good grease on my site i use on my boats I put it together in thick and thin formulas it works great for me.
search the web Z-OPT rc grease

It actually looks EXACTLY like the Grim Grease... Not sure if it is or not, but it has the same color and feel...

I just like the cool applicator. Have one similar to it for my real boat.

I use this stuff.

That very same applicator is used by Manitou who make mountain bike suspension forks, I think its a pretty common applicator that several different industrys use for tubes of their greases. I got mine from a cycle shop many years ago so dont have to buy one just the tube of grease.

Hi that grim grease is nothing but grease used for real cars for packing bearings you can tell by the smell of it.... does the proboat grease have the same smelly smell to it?
I can tell the grim grease is the stuff used on real cars because of the smell and even when you wash it off your hands still have that stink left on them... same smell with the real car bearing packing grease.

No, it doesn't stink, and having packed MANY, MANY car bearings over the years, I don't think it's just car grease... It holds up in the water better than that stuff would. I haven't noticed any unusual smell with the Grim grease either. Either way, both work great.

I have some marine grease from NAPA, which is more of a milky green color, and it, while being expensive, and made for water applications, work OK, but doesn't seem to cling to the flex as well as the other two mentioned do.

NOW, on some applications, I actually just use Marine lower unit oil, and reapply it every round.

There are a BUNCH of ways to go about this. This is just how I happen to do it.

[Diegoboy]

I know the smell you're talking about with the grim grease...

I use one of THESE for the Nano grease posted earlier

Do any of you use grease nipples of some sort so you dont have to keep taking the flex shaft out.

Nope, but one can build into a flex shaft a means to grease it in this manner. That, plus a hole in the strut to get grease in there.
