Boat trailer wheels

Compensated lube oil for boat trailer wheels?
Water in wheel bearnings has been a on going problem for over 50 years. There are many Band-Aid system in use today that may help, none keep the water out. Till now. Fill the hub with lube oil,cut in asmall seal bypass line(1/4) up to a small resivoir (2oz) with vent line down to divers bell mounted on axel. Wa La Boomb shell lubercating system maintance free that works. Smile

Isn't Amsoil grease lithium based? If so, it's hardly going to do a good job resisting water. Lithium is for squeaky door hinges, not boat trailer wheels. I use Red Line CV-2 organic molly based grease and it works well. It is more expensive but you don't need very much and my almost 20 year oil traler is doing fine with just regular maintenance and occasional seal replacement.

This particular grease (Amsoil Water Resistant Grease) is lithium complex grease but I (really) do not see any (technical) reason why it wouldn't be suitable for boat trailer bearings. Opposite of your opinion - it is (almost specially) formulated for wet service conditions. It has outstanding (or incomparable if it sounds better) wash-out characteristics what is the first and most important thing for such as use in paper mill plants or assemblies exposed to prolonged standing or pressurized water. (I’ve made some “home tests” with pressure washer and had very good results with Amsoil Water Resistant Grease. These hasn't been any kind of "official tests" but were good enough for obtaining confidence).

If you ask me I would never use molly (fortified) grease for any (trailer) wheel bearing. You are going to agree with me that molybdenum disulfide consists of small particles. Small, but particles! That means: grease with molybdenum disulfide is colloid. Regarding that my question is: what these particles suspended in grease can cause in so “tight environment” such as bearing? Just wearing!

Lith grease is very good at water washout even better if formulated with polymers. Moly at 2-3% will not help a roller bearing much but will not hurt it either.

What would be more beneficiary for bearing exposed to frequent submerging than lubricant with outstanding wash-out resistance? So, you just posted opposite view of Barkerman's (hinges idea!)?

Regarding how much boat trailer is in use I completely agree with you that moly wouldn't hurt its bearings. But, I still wouldn't use moly fortified grease for (let's say) 48' trailer which is almost 24-hours in use.
