I see that they now have a caveat that these are for freshwater only. Presumably a CYA due to people being a little careless with upkeep. The box sections no doubt have no plating on the inside, but the metal is very heavy and a combination of rinsing off and some waxy-oily treatment annually should keep them clear of significant rusting. Mine are in new condition after 18 months, but that is in freshwater, but still I would have no hesitation in using them in salt water, given the big difference they make in centering a boat.
I now use them on a 25' by 8'6" boat with 25" draft and weighing 7200lbs on its tandem axle trailer, so almost identical to an A25. The only modification necessary was replacing the eight 6" bolts with 7", due to a larger section on the trailer frame.
This is a recent picture of the larger boat:
