The hubs appear to be made of steel, not cast i guess ?
How tough is it going to be to drill 13mm holes into the inner cheeks for irrigation ?

Yes i know that will total the hubs for road use :)

The brake parts have been removed already.
Thinking the fresh water rinsing will extend the life of the sealed bearing ?
It is used as a launching trailer only.
 
I wouldn’t worry about it too much as its only a launching trolley. Its road trailers that suffer when they have travelled and the hub gets warm then its backed into cold seawater causing it to cool quickly and suck in seawater. A better solution is what I had on my road trailer where the dust cover is replaced with one that had a flexible membrane in it and a grease nipple, you keep it full of grease and when its submerged the membrane flexible membrane stops any vacuum forming which encourages water to enter.

There are usually holes already drilled and tapped for that very purpose

A product called "Bearing Buddies" also is a good option, working on a spring pressured plate principle after the grease is pumped into a cap reservoir arrangement

These don't work with sealed bearings as per OP's original post.
They are brilliant with taper roller bearings.
