Boat trailer bearings: Oil vs Grease, which type is best?

I have a 1987 Caulkins Trailer which carries my 19 foot boat. I'm considering
changing my original grease type hubs which also have "Bearing Buddies", with
the new "Turbo Lube" oil submersed bearing trailer hubs from Tie Down
Engineering. However, I'm concerned that the oil type hubs may have problems
with water entering them when dunking the trailer upon launching.
I've had a lot of problems with the grease in my current hubs constantly
squirting out of back side of the hubs upon submersing my trailer in the water.
I've change the rear seals and still have the problem. I've been told that
there is probably an air pocket within the grease in the hub and upon
driving/heating them up then submersing them in water, this is what happens. I
will be installing stainless steel wear sleeves on the inner part of my spindle
to prevent either grease or oil from escaping.
Has anyone one had experience with both type of hubs? Which hub causes less
problems?
I just bought a trailer from M and M Marine in NC. It's a Hi-Tech
brand. They use the Accu-Lube system. This is similar to a bearing
buddy, but sealed at the back.
You squirt the grease into a Zerk fitting on the outside while
spinning the wheel, just like a bearing buddy, but the grease goes
through the center of the bearing, and comes back out the front after
traveling over/through the roller bearings. Wipe of the excess before
putting the cap back on, and you have successfully repacked your
bearings without removing them.
My trailer will sit most of the season, so this, I think, is best for
me. If you'll be doing some serious mileage, maybe the wet ones would
be better.
