My Loadmaster trailer has oil bath hubs (not sure what brand). My marine mechanic told me they use 90 wt gear oil. My question is, can I use the same oil in the hubs that is used in my lower unit or does it use a different oil? Would be handy to stock only one heavy oil and pump.

I would guess you could use the same oil but I'd remove them and put greased hubs on the trailer. Oil hubs are famous for their lubrication on trucks and vehicles that are on the road all the time, but most boat trailers sit in the yard 99% of the time and the oil in oil bath hubs sits in the bottom half of the hub during that time...so the top half of your bearings are exposed and aren't oiled or protected against rust... and temperature changes can cause condensation inside the hubs...again causing rust issues..
But if you use the trailer once a week all year long, you're probably safe.
I had considered getting oil bath hubs at one time, but after doing a little research I decided they weren't for me.

I've heard concerns as well, but the first time that I heard that one. The usual concern (a valid one) is that they won't run far if they lose the gear oil.
Do you know if you have to use different hubs and bearings to make the switch over, or just pop 'em off, pack the bearings and hub, and then put caps or Bearing Buddys on? I've always run packed bearings and not opposed to going back, just thought I would give the oil bath type a shot first since they came on the trailer and the previous owner loved them. Old salts can learn new tricks, so I try to be open minded!

If I rememebr correctly, you can use the same hub but it's been a while since I looked into instaling them... like I said, I decided against them after learning about the problems people with them had with corrosion but having never actualy bought and installed them, I can really only pass along what I've been told about them... I do remember the concern about not going far if they were to break or leak and if they were run dry you'd probably have to replace all the bearings and possibly the axle if the spindle was damaged.. they might lubricate better than any other while going down the road but there's just too many things that could go wrong with them IMO
