I was just curious if keeping your trailer in the water for up to a half hour is Ok for the bearings? Every now and then I like to work on my boat while it's in the water on the trailer and I've been told it's OK since they have seals that protect from water. What's your thoughts?
 
Bearing buddies are a nice addition for what you want to do. Easy to add grease and pushes any water out. Seals better than the basic caps.
 
I do have bearing buddies on there. How often should you add grease?
 
I used to give mine a shot after every time out. It was easy and didn't take up much time. I did this to evacuate any salt water making it's way to the bearing. Probably a bit excessive but I really hated working on my trailer.
 
If you add grease often where does the excess grease go? Will it blow out a seal?
 
If you have bearing buddies the grease will vent out the cap and make a huge mess of your wheels when you tow it away. You don't need to add grease every time. Just add enough grease in there to keep positive pressure.
