Tony's right. No grease. It's not going to fall apart and new balls are cheap when you need a replacement after 20 years.

You should be more concerned that you:

-Have the right tow vehicle
-The boat is in the proper position on the trailer and well supported
-You have a spare tire (and hub)
-Existing hubs are full of grease
-You have transom tie downs
-Safety chains are all in place
-Trailer brakes are working properly
-Lights are all working
-Etc....

I'm about to tow my 24 ft I/O (5,000+ lbs) from NY to Florida with a
newly purchased trailer. In the process of shaking everything down in
advance, I've noticed that the hitch ball is getting scratched up
quite a bit. Question 1, is this normal or should I be concerned?
Question 2, would it make sense to pre-lube the hitch ball with a
light coat of grease or is that a bad idea?
