Pump Cone...Got Grease?
I have been doing some research on pump cone grease after noticing the svc manual called for Epnoc AP#0. I remember the original grease in there looked like a lightweight white lithium grease. I had added some waterproof synthetic grease when I went to a larger pump cone, but it looks like that might not have been the best thing to use. After reading some old threads in the 2-stroke section & Riva forum, it looks like you want something more liquid so that it will circulate back through the bearings instead of sticking to the outside of the pump.
see the Fercho posts:
If you are using grease in the pump it was recommended to dilute it 50/50 with gear oil(Amsoil 75W-140). It sounds like a good idea to me. Anyone have an opinion on this?

thats real interesting we use 85/140 hypoid gear oil in our drive axles so i may try this next time i have my cone off.

I was reading about this too this week. I have 95 hours now and it's almost time to check it. Here's a thread i found in my search.http://www.greenhulk.net/forums/show...+cone+grease.. I think i'm going to go with the 50/50 amsoil mix since I need to order another case of oil anyway.

When I re-built my pump, I talked to Amsoil and the tech dept. guy said that greases and oils have incompatible components. Actually, he said something more technical by describing the components that are not compatible.
However, I was PM'd by some Wise Ones here on the forum that have been doing that for years with great results.
Here's the thread I started on this subject: http://www.greenhulk.net/forums/show...ube&highlight=.
I ended up having a ton of trouble finding the OEM lube (which is THICK). Jerry had it in the store but for some reason it's not there any more. Personally, if I had much trouble finding it again, I would just find some thick marine grease and use that.

Island Racing sells a Marine Synthetic Liquid Pump Grease for the pump.

why buy it when you can mix it up yourself?
gear lube and grease... mix it up to a slurry and your good to go...
Amsoil waterproff grease and Amsoil gear oil is what we used...
to be more specific contact DrewNJ, he made the slurry.

I really like this mixture. 2 seasons now and the pump spins fine.
after you mix the slurry, you can place the bottle in a hot container of water to heat up the slurry and this made it a bit easier to pour in the cold parts of the country!
I would think you would want to fill it just past the bearing surface.
also you`d want to clean out the old crap before you install the new...
