I think those are turbo lubes but a few people make them,i think around 85-90 bucks each.Hubs can get hot after a road trip so if you back in to launch right away you can crack something or suck water into your bearings when their still hot,thats what cool downs about,usually takes me a minute to get ready to launch anyways.The nice thing about the liquid hubs(30 wgt oil)is you can see the level visually and if you suck water its easy to see(turns milky),you can drain them super easy and refill halfway and your good to go.I had bearing buddies on other boats,just give them 1 pump with the grease gun after you pull the boat out to force the water out,dont overgrease them or the grease will bypass the seal and get flung up all over the side of the boat.
