Location: Grand Rapids MN | You can find a pretty good grease for not a lot of money. I would use a grease with a synthetic base oil and a lithium complex thickener. A plain lithium (or sometimes labeled lithium 12-hydroxy) is fine but the lithium complex has what are called complex 'soaps' that help resist washout and water absorption. This is a key characteristic you would like to have for any bearings that get submerged. Most bearing greases will have some moly in it but that's not really important. Moly is just a solid lubricant added for addition protection but its really the base oil that does the bulk of the protection. You also can't tell what's in a grease by color. Manufacturers add dyes so they can easily identify their products out in the field and to seperate them from one another for the user. They seem to follow trends (like marine being blue, etc) but I wouldn't rely on that. Anyways, most of what you will find on the shelf is a lithium based thickener so you can mix them without having to worry about it but if you see a Polyurea grease I would not recommend mixing them. You could run into problems.
Good luck with the project.....
